14 CFR Part 91: General Aviation
Accident occurred Monday, November 25, 2013 in Graniteville, SC
Probable Cause Approval Date: 10/21/2015
Aircraft: PIPER PA-23-160, registration: N4016P
Injuries: 1 Fatal.
NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
During the initial climb after a night takeoff, the left engine lost power. A witness reported that the pilot attempted to return to the runway he had taken off from, but he lost control. The airplane descended, struck trees, and came to rest next to a taxiway that paralleled the departure runway.
Examination of the wreckage revealed that the airplane had not been configured for single engine flight; the left engine's propeller was not feathered, and the landing gear was down. Because the hydraulic pump was installed on the left engine, it would not have been operating after the engine lost power. Therefore, the pilot would have had to manually retract the landing gear by pumping the emergency pump handle 30 to 40 times. However, given the pilot's decision to return to the airport, he may have elected not to retract the landing gear. With the left engine's propeller not feathered and the landing gear down, the airplane would have rapidly decelerated unless the pilot lowered the airplane's nose to maintain airspeed. Additionally, in order to maintain control during the right turn, the pilot needed to counteract the tendency for the airplane's bank angle to increase due to the asymmetrical power from the right engine. The airplane's airspeed likely decreased below the single engine minimum controllable airspeed (Vmc), which resulted in the loss of control.
Before the accident, the pilot conveyed concerns about the airplane's left fuel valve control to two separate airframe and powerplant mechanics. During the conversations, he detailed his plans to troubleshoot and attempt to repair the problem himself. The mechanics urged the pilot not to perform the maintenance himself and to have the problem diagnosed by a knowledgeable certificated mechanic. The pilot was not a certificated mechanic and was not authorized to perform maintenance on the accident airplane.
Postaccident examination of the airplane's fuel system revealed that, although the left and right fuel valve controls were selected to the main tank positions, the left and right main fuel tank shutoff valves were closed, and the left and right auxiliary fuel tank shutoff valves were open. Therefore, the left and right engines were being supplied with fuel from their respective auxiliary tanks instead of from the main tanks. The fuel tanks were damaged; however, fuel was observed in the corners of the left and right main tanks and in the right auxiliary tank, but the left auxiliary fuel tank was devoid of fuel. Therefore, the left engine loss of power was due to fuel starvation.
Examination of the fuel valve control cable assemblies revealed that neither the left or right cable assembly was connected to its respective auxiliary fuel valve arm assembly, which controlled both the main and auxiliary fuel shutoff valves. Because the securing hardware was still in place and was undamaged, it is likely that the control cable assemblies had, at some point, been disconnected from the arm assemblies and not reconnected. This resulted in the engines receiving fuel from the auxiliary tanks when the fuel valve controls were selected to the main tank positions. Given the pilot's discussions with the mechanics, it is likely that he disconnected the control cable assemblies from the arm assemblies when he attempted to troubleshoot the problem.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's improper maintenance of the airplane's fuel system, which resulted a loss of power in the left engine due to fuel starvation. Also causal was the pilot's failure to maintain minimum controllable airspeed following the loss of engine power, which resulted in a loss of airplane control.
On November 25, 2013, about 1804 eastern standard time, a Piper PA-23-160, N4016P, was substantially damaged when it impacted trees after a loss of engine power during departure from Twin Lakes Airport (S17), Graniteville, South Carolina. The airline transport pilot was fatally injured. Night visual meteorological conditions prevailed for the personal flight conducted under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91.
According to a witness, prior to the flight the pilot checked all of the airplane's external lights and ran both engines for a long period of time while in front of the hangar where it was kept. He next observed the airplane depart from runway 6. During the takeoff, the airplane lifted off about 1,500 feet down the runway from the point where the takeoff run began.
After lifting off, the airplane turned abruptly to the left while climbing. When it was just above the approximately 90-foot high trees located on the north side of the field, the airplane appeared to enter an aerodynamic stall, strike the trees, and then fall to the ground. The witness believed the pilot was trying to turn back to the runway when the accident occurred.
According to another witness, who was in a hangar after the airplane departed from runway 6, he heard "chatter" on the radio in the hangar but could not understand what the accident pilot was saying. About 10 seconds later, the airplane passed behind the hangar he was in, sounding "low" to the ground and possibly running on one engine. Moments later he heard the airplane impact trees. The witness stated that he believed that the accident pilot may have been attempting to land on Rachel Avenue when the accident occurred.
PERSONNEL INFORMATION
According to Federal Aviation Administration (FAA) and pilot records, the pilot held an airline transport pilot certificate with a rating for airplane multi-engine land, commercial privileges for airplane single engine land, and a flight instructor certificate with ratings for single, multiengine, and instrument airplane. He also held a ground instructor certificate with ratings for advanced and instrument, a repairman experimental aircraft builder certificate for a Sonex kit airplane he built, and a control tower operator certificate, which he was issued when he was previously employed as an air traffic controller. He did not hold an FAA mechanic certificate
His most recent FAA first-class medical certificate was issued on October 24, 2013. According to FAA and pilot records, he had accrued approximately 1,652 total hours of flight experience. Approximately 361 of those hours were in multi-engine airplanes, of which, 26 hours were in the accident airplane make and model.
AIRCRAFT INFORMATION
The accident aircraft was a twin engine, low wing airplane of metal construction. It was equipped with retractable landing gear and powered by two 160 horsepower, air cooled, normally aspirated engines equipped with two bladed constant speed propellers.
According to FAA airworthiness and registration records the airplane was manufactured in 1958 and was purchased by the pilot on May 9, 2013. Review of maintenance records revealed, it had been modified from its original configuration by the addition of numerous upgrades including updated avionics, an autopilot system, dual alternators, and dual vacuum pumps the airplane's most recent annual inspection was completed on August 1, 2013. At the time of the accident, the airplane had accrued 3675.6 total hours of operation.
METEOROLOGICAL INFORMATION
The recorded weather at Aiken Municipal Airport (AIK), Aiken, South Carolina, located 9 nautical miles east of the accident site, at 1755, approximately 9 minutes prior to the accident, included: winds 070 at 5 knots, 10 miles visibility, overcast clouds at clouds at 3,000 feet, temperature 08 degrees C, dew point -03 degrees C, and an altimeter setting of 30.40 inches of mercury.
According to the United States Naval Observatory on the day of the accident, the moon had set at 1236 and was in its last quarter at 1428. Sunset occurred at 1720, and the end of civil twilight occurred at 1747.
AIRPORT INFORMATION
Twin Lakes Airport was a privately-owned fly-in residential community, located four miles northwest of the central business district of Graniteville, South Carolina. It was classified by the FAA as a non-towered public use airport. The airport elevation was 540 feet above mean sea level and there was one runway oriented in a 06/24 configuration. Runway 6 was asphalt, and in good condition. The total length was 4,000 feet long and 60 feet wide. It was marked with basic markings in good condition. Runway 6 was surrounded by buildings and trees, and the threshold was displaced by 390 feet on the approach end, and 421 feet on the departure end.
Obstacles were present off the approach end of the runway in the form of a 52-foot-tall tree, located 624 feet from the runway threshold, and 89 feet left of the centerline, which required an 8:1 slope to clear. The approach ratio to the displaced threshold was 20:1. Obstacles were also present on the departure end of the runway in the form of a 43-foot-tall tree, located 877 feet from the departure end of the runway, 187 feet left of the centerline, which took a 15:1 slope to clear.
WRECKAGE AND IMPACT INFORMATION
Accident Site Examination
The accident site was located north-northwest of the airport, at the edge of a forested area. Examination of the accident site revealed that the airplane after striking trees and falling to the forest floor came into contact with the ground with its left wing, then nose, at an approximately 45-degree nose down attitude while turning to the left. It then slid approximately 15 feet, until it came into contact with the bases of some trees, where it came to rest in a nose down, left wing low attitude against their trunks. There was no appreciable wreckage path present, and all of the primary components of the airplane were collocated within 15 feet of the first point of ground impact, near where the airplane came to rest.
Wreckage Examination
Flight control continuity was established from the control wheel and rudder pedals in the cockpit and to all of the flight control surfaces. The fuselage and wings displayed multiple areas of crush and compression damage. The aft fuselage was bent about 20 degrees to the left of the fuselage centerline and the right wing was bent down and aft, and was partially separated at the wing root. The left wing was also partially separated at a point about 2 feet outboard of the wing root, was displaced aft, and was folded under the fuselage. The fuel tanks were damaged during the accident however, evidence of fuel being onboard the airplane was present in the form of fuel odors, and fuel being observed in the corners of the left and right main tanks, and the right auxiliary tank. No fuel was visible in the left auxiliary tank.
The master switch was in the on position, the flaps were retracted, and the landing gear was extended. The emergency hydraulic pump handle was stowed. The magneto switches were on, the carburetor heat controls were off, and the engine fuel primers were in and locked. The throttle control levers, propeller control levers, and mixture control levers were full forward prior to impact, and the left and right fuel valve controls were in the main tank positions.
Right Engine and Propeller Examination
The right engine remained attached to the airplane by the tubular engine mount. A tool was inserted in the vacuum pump drive pad and the drive train was rotated. Continuity of the crankshaft to the rear gears and to the valve train was confirmed. Compression and suction was observed on all engine cylinders. The interiors of the cylinders were examined using a lighted borescope and no anomalies were noted.
The carburetor remained attached to the engine. The bowl screw safety washers were in place and no fuel stains were noted on the external surfaces of the carburetor. The venturi was observed to be secure. About an ounce of blue liquid with an odor consistent with that of aviation gasoline was observed in the carburetor bowl. The liquid tested negative for water using water finding paste. No damage was noted to the brass floats or the other internal carburetor components. The carburetor fuel inlet screen was absent of debris. The engine driven fuel pump remained attached to the engine and no damage was noted and the pump would produce air at the outlet port when operated by hand.
Both magnetos remained attached to the engine and no damage was noted. The magnetos were removed and both produced spark from all electrode towers when rotated by hand. No damage was noted to the engine ignition harness, and the spark plugs electrodes were undamaged and displayed normal coloration.
Oil was observed in the engine and no debris was noted in the oil pressure screen. No damage was noted to the oil cooler or associated hoses.
The propeller remained attached to the engine crankshaft flange. One propeller blade displayed evidence of S-bending and was curved aft about 30-degrees at approximately the mid-span point of the blade, and curved forward approximately 20-degrees at a point about 8 inches inboard of the blade tip. The other propeller blade displayed chordwise scratching.
Left Engine and Propeller Examination
The engine remained attached to the airplane by the tubular engine mount. A tool was inserted in the vacuum pump drive pad and the drivetrain was able to be rotated. Continuity of the crankshaft to the rear gears and to the valve train was confirmed. Compression and suction were obtained from all engine cylinders. The interiors of the cylinders were examined using a lighted borescope and no anomalies were noted.
The carburetor was fractured across the throttle bore and partially separated from the engine. The bowl screw safety washers were in place and no fuel stains were noted on the external surfaces of the carburetor. The venturi was secure. About 2 teaspoons of blue liquid with an odor consistent with that of aviation gasoline was observed in the carburetor bowl. The liquid tested negative for water using water finding paste. No damage was noted to the brass floats or the other internal carburetor components. The carburetor fuel inlet screen was absent of debris.
The engine driven fuel pump remained attached to the engine and no damage was noted. The pump produced air at the outlet port when operated by hand. Partial disassembly of the pump revealed no damage to the rubber diaphragms or other internal components. Both magnetos remained attached to the engine and no damage was noted. The magnetos were removed and both produced spark from all electrode towers when rotated by hand. No damage was noted to the engine ignition harness, and the spark plugs electrodes were undamaged and displayed normal coloration.
Oil was observed in the engine and no debris was noted in the oil pressure screen. No damage was noted to the oil cooler or associated hoses.
The vacuum pump remained attached to the engine. No damage was noted, and when removed the pump produced air at the outlet port when rotated by hand. The drive coupling, carbon rotor and carbon vanes were intact.
The propeller remained attached to the engine crankshaft flange. The spinner displayed heavy crush damage only on one side of the spinner, and minimal damage on the other. One propeller blade was bent forward about 10-degrees approximately 18 inches inboard of the propeller tip and exhibited trailing edge gouging and chord-wise scuffing near the trailing edge of the blade. The other propeller blade was bent aft about 5 degrees at about 18 inches outboard of the hub.
SURVIVAL ASPECTS
Examination of the wreckage revealed that the tubular steel structure which surrounded the cabin had remained relatively intact and that cabin volume integrity had only been minimally reduced during the impact sequence. Examination of the occupant restraint system revealed that shoulder harnesses were not installed in any of the seat positions and the lap belts on the front left and right seats were anchored to the seat structure, and not the airplane structure. The pilot's lap belt did not display evidence of stretching, the latching mechanism had remained latched, and the belt attachment fittings had remained attached to the seat. The seat had been displaced from its mounting location, and there was evidence of the pilot having struck the front of the cabin area during the impact sequence.
No shoulder belts were required to be installed under the regulations that were in effect at the time of the airplane's manufacture. As of December 12, 1986, the FAA required that shoulder belts be installed for all seats in small airplanes manufactured since that date. There was no requirement that shoulder belts be retrofitted to airplanes made prior to that date but. Piper Aircraft issued Service Bulletin (SB) 980 on January 18, 1995, which required the installation of shoulder belts in any airplanes where they were not originally equipped. Piper considered compliance with the SB mandatory.
According to the FAA Civil Aerospace Medical Institute's publication AM-400-90/2, seat belts alone only protect occupants in minor impacts; however, the use of shoulder belts was found to reduce major injuries by 88 percent and fatalities by 20 percent.
MEDICAL AND PATHOLOGICAL INFORMATION
An autopsy was performed on the pilot at the Newberry County Memorial Hospital Morgue on behalf of the Edgefield County Coroner. The listed cause of death was blunt force injury of the head.
Toxicological testing of the pilot was conducted at the FAA Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma. The specimens from the pilot were negative for carbon monoxide, basic, acidic, and neutral drugs with the exception of:
- Ibuprofen which was detected in Urine, and was a nonsteroidal anti-inflammatory drug with analgesic and antipyretic activity.
- Ranitidine which was detected in Blood and Urine, and was an over-the-counter (OTC) histamine H2-receptor antagonist used to decrease the production of gastric acid, treat ulcers, and a number of other stomach ailments.
- Salicylate which was detected in Urine, and was an aspirin metabolite, an OTC anti-inflammatory medication to treat aches and pains, an antipyretic to reduce fever, and also had an antiplatelet effect used to reduce the risk of myocardial infarction.
TESTS AND RESEARCH
Checklists
Review of the documentation found in the wreckage revealed that a checklist was onboard within reach of the pilot which listed both normal and emergency procedures.
Further review of the checklist revealed information in the pretakeoff checklist which required that the electric auxiliary fuel pumps be selected to the "On" position. The checklist also addressed engine failure in flight. It required that the pilot to "Maintain Control/Pitch/Airspeed" which directed that the airplane's speed be maintained at critical engine-out minimum controllable airspeed (Vmc) of 73 miles per hour, that the landing gear and the wing flaps be moved to the "Up" position and that the inoperative engine's propeller be selected to "Feather." It further required that the pilot accelerate to 95 mph, which was the best rate of climb speed single engine (Vyse) for the airplane.
At the time of the airplane's manufacture, the Civil Aviation Regulations only required that flight at Vyse to assure minimum sink rate. It did not guarantee that the airplane would be able to maintain altitude, particularly in the takeoff or landing configuration with one engine inoperative.
Propeller Feathering
The propellers on the airplane were constant speed, controllable, fully feathering units. These were controlled by the use of propeller pitch levers in the center of the control quadrant. Feathering of the propellers was accomplished by moving the controls fully aft through the high pitch detent into the feathering position. Feathering was expected to occur within 10 seconds. The propellers could be unfeathered by moving the propeller control forward, and pressing the engine starter buttons. Examination of both propellers revealed that neither was feathered.
Landing Gear System
The airplane was equipped with retractable tricycle configuration landing gear system, incorporating a steerable nose wheel. Examination of the system did not reveal evidence of any preimpact malfunction or failure, that the landing gear handle was in the neutral position, and all three landing gear were down.
The position of the landing gear was indicated by four lights located on the pedestal. When the green lights were illuminated, all three legs of the landing gear were down and locked; when the amber light was illuminated, the landing gear was up, and when no lights were illuminated, the landing gear was in an intermediate position. A red light in the landing gear control handle knob would flash when the landing gear was up and either one of the throttle levers were reduced below approximately 12 inches of manifold pressure. With the landing gear not in the down position, a landing gear warning horn would annunciate.
To guard against inadvertent retraction, of the landing gear on the ground, a mechanical latch, which must be operated before the landing gear control could be moved upward, was positioned just above the control lever.
A hydraulic system was used for the extension and retraction of the flaps and landing gear. Pressure was supplied to the control unit from an engine driven pump that was mounted on the left engine. Examination of the hydraulic system did not reveal any preimpact failures or malfunctions.
In the case of the landing gear, when the landing gear handle was moved from the center "Off" position and placed in either the retraction or extension (up or down) position, the hydraulic system would actuate the landing gear, and when it was either fully up or fully down, hydraulic pressure within the selector valve unit would force the landing gear control lever back to the "OFF" (neutral) position, which would then allow the hydraulic fluid to circulate freely between the pump and control unit. Landing gear retraction or extension would normally take between 10 and 12 seconds.
The airplane was also equipped with an emergency hydraulic pump which was integral with the selector valve unit and was used to obtain hydraulic pressure in the event of a hydraulic pump failure or failure of the left engine. To operate the emergency pump, the retract or extend the landing gear or flaps, the pilot would have to extend the handle to its full length by pulling aft and then position the landing gear handle to the position desired, then pump the handle 30 to 40 strokes to either raise or lower the landing gear.
The airplane was also equipped with an emergency hydraulic pump which was integral with the selector valve unit, and was used to obtain hydraulic pressure in the event of a hydraulic pump failure or failure of the left engine. Operation of the pump required the pilot to manually articulate handle between 30 and 40 strokes to either raise or lower the landing gear. In the event that a hydraulic system failure should occur due to a line breakage or selector valve malfunction, an independent system that could be pressurized with carbon dioxide from an onboard bottle was installed to enable the pilot to lower the landing gear.
Fuel System
The fuel system consisted of two 36 gallon main fuel cells (tanks) located outboard of the engines, and two 18 gallon auxiliary fuel cells located in the outboard sections of the wing. Fuel could be pumped by the engine driven fuel pumps from the tanks directly to the adjacent carburetors. The fuel valves could be left open at all times, and the crossfeed left in the off position.
Electric auxiliary fuel pumps were also installed in by-pass fuel lines between the tanks and the engine driven pumps. The electric pumps could be used to provide pressure in the event of a failure of the engine driven pumps. They would normally be turned on to check their operation before starting the engines, and left on during takeoff and landing, to preclude the possibility of fuel pressure loss in the event of an engine driven pump failure at critical times. Examination of the electric auxiliary fuel pumps switches revealed that they were in the "OFF" position.
If desired by the pilot, the fuel could also be pumped by the operating engine driven pump to the engine with the failed engine driven pump, by turning on the crossfeed. The good pump would then supply both engines from its tank. If this tank ran low on fuel, fuel could then be drawn from the opposite tank by turning on the electric pump on the failed engine driven pump side, leaving the crossfeed on, and turning the fuel valve on the empty tank off. Then the electric pump on the failed pump side would be supplying both engines from its tank.
Fuel could then be used from one tank or the other, by shutting off one main valve and turning on the crossfeed to balance fuel loads. For normal operation, it was recommended that fuel be pumped directly from the tanks to their respective engines with the crossfeed off.
The fuel valve controls and crossfeed control were located with the engine primer pumps in the fuel control panel between the two front seats. Examination of the crossfeed control revealed that it was in the "OFF" position. The left and right fuel valve controls were in the "ON MAIN 36 GAL" (main tanks) positions, and the spring-loaded locks, which prevented unwanted movement, were engaged. Examination of the fuel tanks' fuel shutoff valves revealed that the position of the valves did not agree with the fuel valve controls' positions, as the main fuel tanks' shutoff valves were closed, and the auxiliary fuel tanks' shutoff valves were open.
Examination of the fuel valve control cable assemblies which actuated the main fuel shutoff valve, and the auxiliary fuel shutoff valve, revealed that right fuel valve control cable assembly was of a different type than the left fuel valve control cable assembly, and appeared to be newer.
Further examination of the fuel valve control cable assemblies also revealed, that the cables were each attached to their respective fuel valve controls on the fuel control panel, and were connected to their respective fuel control cable support arms which were also used through the use of switch assemblies mounted above the support arms, to communicate to the fuel gauges which tank was selected, so the gauge could indicate the fuel quantity in the selected tank. It was discovered however, that neither the left or right cable assemblies were connected to their respective auxiliary fuel valve arm assembly which controlled both the main fuel shutoff valve, and through a turnbuckle and control arm, the auxiliary fuel shutoff valve. This was despite the fact that the securing hardware which consisted of two AN 393-15 pins secured by two AN 380-2-2 cotter pins, were still in place and were undamaged.
ADDITIONAL INFORMATION
A few weeks before the accident the pilot had flown the airplane to Pennsylvania to visit a relative. Upon his return he had contacted an airframe and powerplant mechanic that had previously performed an annual inspection on the airplane, and advised him that when he had switched tanks while flying the airplane home, the left engine "stumbled."
The mechanic advised the pilot that a cable might have gotten stuck, that he could check it for him, and that it probably needed lubrication. The pilot then told him that "he might try to lubricate it." The mechanic then advised him once again, to call him if he wanted to look at it but, the pilot advised him that "he would take the mid-belly pan off of the left side and take a look at it."
The pilot never called him back.
According to another airframe and powerplant mechanic the pilot had called him about 7 to 14 days prior to the accident about having a problem with the left fuel valve control. The pilot advised him that the fuel valve control was stiff or binding and that "he had gained access to the selector" and noted flexing in the cable upon tank selection. He asked what would cause this, and were there any adjustments that could be made to the linkage to ease the binding. The mechanic advised the pilot that there could be a number of reasons for the binding including a clogged, corroded, or dirty fuel valve, internal corrosion, friction in the cable, or the cable coming loose somewhere in the airframe where it was attached along its routing between the valve and the fuel valve control, thus causing the cable to flex and bind rather than operate normally. He strongly urged the pilot to get together with a knowledgeable mechanic with proper tools and documentation and have the problem thoroughly troubleshot and solved.
14 CFR Part 91: General Aviation
Accident occurred Monday, November 25, 2013 in Graniteville, SC
Aircraft: PIPER PA-23-160, registration: N4016P
Injuries: 1 Fatal.
This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On November 25, 2013, about 1804 eastern standard time, a Piper PA-23-160, N4016P, was substantially damaged when it impacted trees, after a loss of engine power, at Twin Lakes Airport (S17), Graniteville, South Carolina. The airline transport pilot was fatally injured. Visual meteorological conditions prevailed for the personal flight conducted under the provisions of Title 14 Code of Federal Regulations Part 91.
According to a witness who was in a hangar with a friend, it sounded to them like the twin engine airplane departed from runway 6. They then heard "chatter" on the radio but could not understand what the pilot was saying. About 10 seconds later the airplane passed behind the hangar they were in and it sounded like it was low to the ground and possibly running on one engine. Moments later they heard the airplane impact trees. The witness stated that he believed that the pilot may have been attempting to land on Rachel Avenue which was behind the hangar he was in, and which paralleled the runway, and was used as a taxiway at the fly-in residential community.
Examination of the accident site and wreckage revealed that the airplane had come to rest in a forested area just off of Rachel Avenue. There was no evidence of any preimpact malfunction or failure of either engine that should have precluded normal engine operation. Further examination revealed however, that the left engine did not exhibit any indication that it was producing power on impact.
Examination of the fuel selectors revealed that both the left and right selectors were in the main tank positions and the spring loaded locks which prevented unwanted movement were engaged. Examination of the main fuel tanks fuel shutoff valves revealed however, that they were closed, and the auxiliary fuel tanks shutoff valves were open.
Examination of the cable assemblies which actuated the fuel shutoff valves revealed that right cable assembly was of a different type than the left cable assembly and appeared to be newer. Further examination of the cable assemblies also revealed that neither the left or right cable assemblies were connected to the push-pull rods which controlled the main and auxiliary fuel tank's fuel shutoff valves. Additionally, none of the hardware required to secure the cable assemblies to the push pull rods was present.
The airplane had recently been purchased by the pilot, and a few weeks before the accident he had flown it to Pennsylvania to visit a relative. Upon his return he had contacted an airframe and powerplant mechanic and advised him that he was having difficulties with the fuel selectors being stiff and hard to move. According to the mechanic, he advised the pilot that the fuel selector and fuel shutoff valve actuating assemblies could be out of adjustment and that he needed to have a mechanic examine the system to make sure that it was working properly and lubricate the linkages in the fuel selector and fuel shutoff valve actuating assemblies. The pilot however never called him back prior to the accident flight.
The airplane was retained by the NTSB for further examination.
Richard Showalter
GRANITEVILLE, SC – Mr. Richard Showalter, 56, beloved husband of thirty-seven years to Susan Showalter, died Monday, November 25th, 2013, doing what he loved, flying his Piper Apache. Born in Baltimore, MD, a son of Lola Showalter, Everett, PA and the late David Albert Showalter, he had been a resident of Westminster, MD for many years. He had been a resident of Culpeper, VA, prior to coming to Graniteville, SC, in 2009. His career as an Air Traffic Controller began in the United States Navy. Following his honorable discharge from the Navy, he went to work in the same capacity with the FAA. Richard had a passion for flying and enjoyed hunting and fishing. He and Susan enjoyed taking their four-legged child “Ziggy” for walks. In addition to his wife and parents, family members include his daughter, Mary Elizabeth and her husband, Imran Chatriwala, and their children, Dorothy Alice and Elyas Imran, all of Stuttgart, Germany; siblings, Virginia Zile, Westminster, MD, Jane Black, and Tammie Dicken, both of Everett, PA and David Showalter, DeBary, Fl. In accordance with his wishes, Richard will be cremated and the family will hold a private memorial service. It has been requested that memorials be made to the: SPCA Albrecht Center for Animal Welfare, 199 Willow Run Road, Aiken, SC 29801. Hatcher Funeral Home & Cremation Service, Langley, SC.
Richard Showalter, who died in a Piper PA-23 Apache crash on Monday, had recently purchased the plane that crashed.
Richard Showalter, 56, died of blunt force trauma after his plane crashed on Monday evening in Edgefield County.
Investigators are still trying to determine the cause of the plane crash that killed an experienced Graniteville pilot on Monday, but an Aiken pilot said Richard Showalter had recently purchased the twin-engine plane that crashed.
Showalter, 56, was the only person aboard the Piper PA-23 when it crashed into some trees near the Twin Lakes Airport just after 6 p.m. on Monday. He died of blunt force trauma to the body and head, according to the Edgefield County Coroner's Office.
The National Transportation Safety Board is investigating the crash and is expected to release a preliminary report next week; however, it will take longer to determine the cause, and the board's final report could take up to a year.
Showalter had more than 30 years experience in aviation, including as an air traffic controller and a pilot. Don Barnes, chief pilot for Aiken Air Service, said he was considering hiring Showalter to fly for the company. He last spoke with Showalter on Nov. 20.
“He told me he got this airplane and was going to do multiengine instruction,” said Barnes, who got his own multiengine rating in a PA-23 like the one Showalter was flying. “It's got some design problems that make it one of the planes I'm very hesitant to fly anymore. It's very underpowered, and that's a bad thing in airplanes.”
The two had spoken on the phone for about a year but never met face-to-face.
According to Barnes, the plane's hydraulic landing gear is on the left engine and operates in a way that if it is not retracted soon enough after takeoff, it could cause the left engine to lose power. The older models had much less horsepower than the newer models.
Showalter had flown mostly turbine-powered twin-engine planes at Daniel Field in Augusta, Barnes said. If a turbine-powered plane loses an engine, it will keep flying; but if an older piston plane, like the PA-23, loses power, the plane can't fly with just the right engine.
Barnes said he'd submitted the paperwork for Showalter to fly with their company and was awaiting approval when they spoke last week.
“I didn't make any comments at the time,” he said of Showalter's news about purchasing the plane. “He didn't ask, I didn't offer any comments. If he would have asked, I would have advised him against it.”
On the Facebook page for his business, Aviation Consulting Expert Services Inc., Showalter wrote that he offered a number of services, including multiengine time building, flight instruction, pilot services and crew resource management training. His last posting was on Nov. 11 – a photo taken above the clouds with the caption, “Somewhere over West Virginia on the flight back from visiting Mom.”

Daylight video of plane crash scene
The National Transportation Safety Board is investigating the small plane crash that killed an experienced Graniteville pilot in Edgefield County on Monday night.
Richard Showalter, 56, died of blunt force trauma to the body and head, according to the Edgefield County Coroner’s Office. Showalter was the lone person aboard the small plane that crashed in the Twin Lakes area at about 6 p.m. on Monday night. Twin Lakes Airport straddles the Aiken County/Edgefield County line.
Eyewitnesses reported seeing the white, twin-engine plane in some trees off Rachel Avenue, its nose in the ground and the tail up in the trees.
The cause of the crash has not been determined. An investigator from the National Transportation Safety Board arrived on the scene Tuesday and will be there for at least a couple of days, according to spokesman Keith Holloway.
“He’s on the scene, gathering factual information, inspecting the aircraft and so forth,” Holloway said.
The board will have a preliminary report on the crash available on its website sometime next week. The full report could take up to a year to put together.
“The preliminary report still does not determine the cause, but there will be some additional factual information,” Holloway said.
A message left with the Edgefield County Sheriff’s Office was not returned.
According to his LinkedIn page, Showalter was a contract pilot with Aiken Air Service. He’d previously piloted for Augusta Aviation and before that worked in a number of air traffic control positions for the Federal Aviation Administration and the U.S. Navy.

Trenton, SC - After a plane went down Monday night at the Twin Lakes Air Park, there were many questions to what happened. Edgefield Chief Deputy Coroner's Office identified the victim as 56-year old Richard Showalter of Graniteville.
After talking to family and friends, they said Showalter was a very experienced pilot. He spent 22-years as an air traffic controller, and was a certified flight instructor.
Alan Swires was sitting at inside a nearby hanger last night when he heard a loud noise outside on the tarmac.
"We heard a low flying plane that was in the back part of the hangar, and the runways in the front part of the hangar… and right after we heard the engine noise, we heard the crash," said Swires.
As soon as he heard the plane go down, Swires said he immediately ran out to the back of the field off Rachel Avenue.
He and his friend checked the man for a pulse, but there was nothing.
"We saw that there was not any way he could of made it," said Swires.
The National Transportation Safety Board arrived to the scene this Tuesday morning to start its investigation on the remains of the Piper PA 23—160.
NTSB Investigator Todd Gunther said they don't know much as of now, but are taking reports from witnesses around the area.
"Witness statements right now what we understand was that there was a noise, either a sputtering noise or what they sensed as a loss of power," said Gunther.
For now the investigation continues into what happened when the twin-engine plane came down.
"Some of the things that we will be looking at as part of the investigation are the weather conditions that occurred at the time of the accident, the physiology of the pilot, and the systems on the airplane," said Gunther.
The NTSB will have results on their investigation of the crash within 5 to 7 days.

BETTIS ACADEMY – One person is dead following a twin engine plane crash in a wooded area off Rachel Avenue parallel to the Twin Lakes airstrip on the Aiken and Edgefield County line around 6 pm. Cpl. Robbie Harter said the plane went down "nose first into the trees", but could not elaborate on the scene. The identity of the pilot has been released.
"We have one fatality," Harter said adding the scene was being secured until investigators from the National Transportation Safety Board (NTSB) could arrive to take over the investigation. "At that time all questions will be referred to them," Harter said.
Deputy Coroner David Burnett said the pilot was Richard Showalter, 56, from Graniteville. "We will have an autopsy tomorrow (Tuesday) to determine the cause of death," Burnett said.
The plane was a 1958 Piper PA23-160 Apache (bottom) and was for sale at the time of the crash. Engine trouble was said to have possibly played a roll in the crash. There are varying reports, most saying the pilot was taking off just before the crash. According to information provided, witnesses heard the takeoff and then the engines "spitting and sputtering" before the plane went down.
Media was kept far away from the scene at a location at the intersection of Rachel Avenue and Michelle Avenue.
TRENTON — A small airplane crashed on Monday night near Twin Lakes Airport, killing one man, who was its pilot. No other people were on board.
“I saw the airplane, and I saw the police cars and the ambulances,” said Eileen Hutson, who lives on Mooney Court near the site of the accident. “It was a white, twin-engine plane. It landed to the right of Rachel Avenue at the beginning of the woods. It was nose down in the ground, and the back of the tail was up against the trees. There was some debris lying to the left of the plane.”
Twin Lakes Airport straddles the Aiken County/Edgefield County line.
“I talked to a guy who went over to the plane before anybody else got there, and he said that he had checked the pilot's pulse; he told me that the pilot was dead,” said Hutson, who took the photographs of the aircraft that appear in today's edition of the Aiken Standard.
According to Hutson, the plane went down around 6:15 p.m. She didn't hear anything, but she knew that something unusual had happened because she got a phone call from her daughter, Terri Cheek, saying that police wouldn't let her into the subdivision where Hutson's house is located. Then, Hutson said, someone phoned her husband with the news that a plane had crashed nearby.
“I drove down there, and when I got there, there was a sea of police cars,” she said. “They already had tape up (to prevent public access to the crash scene).”
The pilot's name had not been released as of press time.
Representatives of the Edgefield County Sheriff's Office provided limited information to the Aiken Standard during the hours immediately following the crash.
Dede Biles is a general assignment reporter for the Aiken Standard and has been with the newspaper since January 2013. A native of Concord, N.C., she graduated from the University of North Carolina at Chapel Hill.
Trenton, SC - One person is dead after a plane crash near Rachel Avenue in Trenton, South Carolina. Investigators don't know what caused the plane crash, but they say it happened just after 6pm.
"We have a single fatality from what appears to be a private plane that has crashed," Emergency Management Director Mike Casey said.
Although details are limited, investigators say a twin-engine plane crashed in the woods near the Twin Lakes Air Park in Edgefield County.
Investigators say they have identified the pilot, but will not release his name at this time.
"The next of kin has not been notified at this time so we are withholding the name because of that. The coroner's office will be sending the remains for an autopsy," Casey said.
Federal authorities are on their way to investigate the crash.
"The scene will be secure overnight until they get here, if they choose to wait until tomorrow, that's their decision, but we have been in touch with them," Casey said.
Right now, investigators don't know what caused the crash, but are interviewing people who live in the area to find out if they saw anything.
"Words to the effect from at least one person that saw the plane, it appeared that it had some type of engine trouble. We're going to research that some more, and the NTSB, once they examine the plane, they will be able to tell us more about that, but it appears that there was some type of problem while he was in the air rather than on take-off or landing," Casey said.
The National Transportation Safety Board will be conducting the investigation.
