Analysis 

The pilot reported that, while on a 3-mile base leg, he encountered a flock of large birds. He aborted the base leg and rapidly descended the airplane to avoid the birds, but the birds followed. The pilot continued the dive and saw power lines nearby. He made an "evasive maneuver (dive down)" to avoid the power lines, but the vertical stabilizer struck the power lines, shearing off the vertical stabilizer and rudder.

The pilot maintained airplane control, climbed the airplane, declared "mayday," and requested flight following to an airport without a crosswind for landing. He approached at a higher airspeed to reduce the airplane's left turning tendencies, and during the landing roll, the airplane veered left off the runway into an adjacent field.

The airplane sustained substantial damage to the vertical stabilizer and rudder.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain clearance from power lines while making an evasive maneuver to avoid birds.

Analysis 

The accident flight was the first flight of the Phase 1 test period for the experimental amateur-built airplane. The private pilot stated that, during the flight, while on the crosswind leg of the airport traffic pattern, the engine experienced a total loss of power and that he noted that there was no fuel pressure indication or electrical system charge. He unsuccessfully attempted to restart the engine with the secondary electric fuel pump and then maneuvered to land the airplane. The pilot reported that the airplane touched down longer and faster than "normal due to a no flap condition" and that the airplane overran the runway, impacted a fence, and came to rest on its nose. The engine mounts and fuselage were substantially damaged.

According to the pilot, the total loss of engine power resulted from an electrical problem due to the use of a lithium motorcycle battery on the airplane, which was not designed for such use, and to his attempt to charge the battery with a charger that was specifically not recommended for use on lithium batteries. The pilot reported that this likely resulted in the battery having a "low charge" at the beginning of the flight. When the alternator subsequently attempted to recharge the battery during the flight, it overheated the battery, which then shut down and resulted in a loss of electrical power and the subsequent loss of engine power.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
A total loss of engine power as a result of the loss of all electric fuel pumps due to a loss of electric power because of the installation of an improper battery on the airplane and the use of improper charging cables on the battery.

Factual Information

On July 2, 2017, about 1325 eastern daylight time, an experimental amateur-built Zodiac CH650B, N650LN, was substantially damaged during landing at Lazy B Ranch Airport (0P8), Dover, Pennsylvania. The private pilot was not injured. The airplane was registered to and operated by the pilot as a 14 Code of Federal Regulations Part 91 test flight. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed for the local flight.

According to the pilot, the accident flight was the first flight of the Phase 1 test period for the experimental airplane. During the flight, while on the crosswind leg of the airport traffic pattern for runway 5, the engine lost total power and the pilot noted that there was no fuel pressure indication or electrical system charge. He attempted to restart the engine with the secondary fuel pump, however, the engine would not start. He maneuvered the airplane to land on runway 5 and stated that the airplane touched down longer and faster than "normal due to a no flap condition." The airplane overran the runway, impacted a fence, and came to rest on its nose.

According to a Federal Aviation Administration (FAA) inspector who examined the airplane, the firewall and engine mounts were substantially damaged. In addition, the alternator and main circuit board were tested with no anomalies noted. The electrical wiring was examined on the airplane with no anomalies noted.

According to FAA records, the airplane was issued an experimental airworthiness certificate on December 16, 2016. The two-seat, low wing, monoplane was equipped with a Continental Motors Inc. O-200 series, 100 hp, engine. According to the airframe maintenance logbook, the most recent condition inspection was performed on June 17, 2017, at a total time of 0 hours. At the time of the accident, the airplane had accumulated 0.8 hours. According to the pilot, the airplane was equipped with primary and secondary electrically-driven fuel pumps. The airplane was not equipped with an engine-driven fuel pump. In addition, the flaps were electrically actuated.

The pilot reported the battery that was used on the amateur-built airplane was a lithium motorcycle battery and "not intended for use on aircraft." In addition, he had charged that battery with a charger that was specifically not recommended for use on lithium batteries. Since he was attempting to charge the battery with an incompatible charger, he thought that he probably started the flight with "low battery charge." Then, when the alternator was trying to recharge the battery, it overheated, and the battery subsequently shut down, resulting in a loss of electrical power to the airplane. Furthermore, the airplane was not equipped with a backup battery, which he reported could have prevented the accident if it was installed. Lastly, he stated that there was no mechanical malfunction of the airplane, that there was an electrical problem "due to the use of a battery not designed for this application and improper maintenance on that battery."

Aircraft: Nunley KR2
Aircraft Damage: Destroyed
Defining Event: Loss of engine power (partial)
Injuries: 1 Serious
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis 

The commercial pilot was preparing to fly the experimental amateur-built airplane on a local, Phase 1 test flight. The pilot reported that ground operations were normal, including the engine run-up. Shortly after takeoff, about halfway down the runway, the engine sputtered, hesitated, and then lost partial power. The pilot had passed the point at which he could land the airplane straight ahead on the runway, so he looked for a place to conduct a forced landing. During the forced landing, he turned the airplane to avoid nearby houses and then steepened the turn due to wind that was pushing the airplane left. The airplane subsequently collided with the ground and fragmented into multiple sections. The pilot did not recall the impact sequence due to injuries he sustained during the accident.

The fragmentation of the airframe was consistent with an in-flight loss of airplane control before ground impact. Examination of the engine, including a full disassembly, did not reveal evidence of any preaccident mechanical malfunctions or failures that would have precluded normal operation. The reason for the partial loss of engine power could not be determined.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
A partial loss of engine power for reasons that could not be determined because postaccident examination of the engine revealed no evidence of any preaccident mechanical malfunctions or failures that would have precluded normal operation.

Findings

Not determined
Not determined - Unknown/Not determined (Cause)


Factual Information

On June 30, 2017, about 1238 eastern daylight time, an experimental, amateur-built KR2, N269HJ, was destroyed following a collision with terrain at Skypark Estates Airpark (18FD), Baker, Florida. The commercial pilot was seriously injured. The airplane was operated by the pilot under the provisions of 14 Code of Federal Regulations part 91 as a personal flight. Day, visual meteorological conditions prevailed, and no flight plan was filed for the local flight that was originating at the time of the accident.

The pilot reported that he was preparing for a local flight as part of the 40-hr phase I test period. The airplane had a total of 12 hours accumulated time and he was the registered builder of the airplane. The preflight operations were normal, he performed an engine run-up, and taxied to the end of the runway for departure. The fuel tank contained 10 gallons of fuel. The takeoff was normal until about half way down the runway, when the engine "sputtered and hesitated" and lost power. He was past the point where he could land on the runway, so he looked for a place to perform a forced landing. He initiated a right turn to avoid nearby houses, but, the wind was out of the north and pushed him to the left. He steepened the turn; however, he realized he needed more power to remain airborne. He stated that the engine never stopped running, but it was not producing enough power. He did not recall the actual impact due to his injuries.

The pilot held a commercial pilot certificate for rotorcraft and gyroplane. He did not hold an airplane single-engine landrating. He stated in an interview that he was ready to take his sport pilot certificate check ride; however, he was unable to complete it due to weather cancelations. He reported 2,000 hours total flight time, including 500 hours in "ultralights."

A witness was on the airfield and observed the airplane as it took off on runway 27. About 300 to 500 ft agl, after takeoff, the engine sputtered and changed sound. This occurred as the pilot began a 45º climbing turn to the right. The pilot then began a "tight" turn to the left and the airplane descended toward the ground. The witness reported that the engine appeared to be running throughout the accident sequence and may have been near idle power during the descent.

An inspector with the Federal Aviation Administration (FAA) responded to the accident site and examined the wreckage. The wings separated from the airframe and were found fragmented. The engine, firewall, and propeller separated from the forward fuselage. The empennage remained attached to the aft fuselage. There was no fire.

The engine was examined by an FAA inspector and a representative from the engine manufacturer. The engine exhibited impact damage predominantly on the under and left sides. The two-blade, fixed pitch, wooden propeller remained attached to the hub and the hub remained attached to the crankshaft. The propeller blades were shattered into numerous pieces.

The carburetor exhibited impact damage. It was broken free from the induction system and the inlet fuel line was separated. The throttle control arm was found loose on the throttle control shaft; however, there was impact damage to the area and the pre-accident condition could not be determined. The carburetor was disassembled, and the internal components were undamaged. The fuel inlet screen was clean.

The left magneto remained attached to the engine with impact damage evident to the distributor section. When rotated manually, it would produce spark on one post. It was removed and examined; the distributor was impact-damaged, and the distributor gear was displaced from impact forces. The right magneto was undamaged and remained attached to the engine. It was rotated manually and produced spark on all leads and in the correct order.

The top spark plugs were removed for examination. The bottom spark plugs exhibited impact damage. The top plug electrodes exhibited minimal wear and light gray color when compared to a Champion inspection chart.

The engine was rotated manually; internal continuity was confirmed, and compression and suction were observed on the No. 1 and No. 3 cylinders. Internal inspection of the cylinder components revealed normal operating and wear signatures. The No. 2 cylinder exhibited impact damage. Further disassembly revealed a fractured mounting stud under the intake valve and the exhaust valve was stuck in the open position. The mounting stud was determined to be from the carburetor and showed signatures of separation during the impact sequence. The exhaust valve was removed and was bent from impact. The No. 4 cylinder also exhibited impact damage to the head with damage to the valves. Other than impact damage, the internal components of the No. 2 and No. 4 cylinders revealed normal operating and wear signatures.

Analysis 

The airline transport pilot applied takeoff power to complete a touch-and-go landing. The airplane's nose turned right, and the pilot corrected with a left rudder application, but the airplane continued turning right. The pilot reduced engine power and then aborted the takeoff and applied left braking, but the airplane continued to the right, departed the runway, and travelled through a depression in the ground before coming to rest. When the main landing gear (MLG) dropped into the depression, the tail section struck the ground, which substantially damaged the tail structure.

The pilot reported that the "right main tire lost all pressure." Examination of the right MLG wheel revealed that the tire and the inner tube had rotated independently of each other on the rim and that the inner tube valve stem was severed. Based on the available evidence, the investigation could not determine whether the tire was flat before the accident or was caused when the MLG hit the depression.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's loss of directional control upon landing.

Findings

Aircraft
Directional control - Not attained/maintained (Cause)
Tire casing - Fatigue/wear/corrosion

Personnel issues
Incorrect action performance - Pilot (Cause)

Collision with terr/obj (non-CFIT)

On June 26, 2017, at 1400 eastern daylight time, an experimental amateur-built Vans RV-10, N865HB, was substantially damaged during a runway excursion after landing at Blairsville Airport (DZL), Blairsville, Georgia. The airline transport pilot and a passenger were not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which departed Lumpkin County-Wimpys Airport (9A0), Dahlonega, Georgia about 1345, and was conducted under the provisions of 14 Code of Federal Regulations Part 91.

According to the pilot, he completed a landing to runway 26, retracted the flaps, and applied takeoff power to complete a touch-and-go landing. The nose turned to the right, the pilot corrected with a left rudder application, but the airplane continued to the right. The pilot reduced engine power, aborted the takeoff, and applied left braking but the airplane continued to the right, departed the runway, and travelled through a "depression" before coming to rest. As the main landing gear dropped into the depression, the tail section struck the ground which substantially damaged the tail structure.

The pilot held airline transport, flight engineer, flight instructor, and private pilot certificates with ratings for airplane single engine, multiengine, and rotorcraft helicopter. His most recent Federal Aviation Administration (FAA) first-class medical certificate was issued May 9, 2017. He reported 21,000 total hours of flight experience of which 100 hours was in the accident airplane make and model.

The four-place, low-wing airplane was manufactured in 2010 and powered by a Lycoming XIO-540D4A5, 260-hp engine. The most recent condition inspection was completed on April 7, 2017 and the airplane had accrued 365 total aircraft hours.

The airplane was configured with a castering nose landing gear and steering was accomplished by asymmetrical braking. The main landing gear was equipped with wheel pants, and according to the pilot, the tires could not be serviced with the wheel pants installed.

At 1400, the weather recorded at Western Carolina Regional Airport (RHP) at 1,696 feet elevation, 21 miles north of DZL, included clear skies, wind from 030° at 3 knots, and visibility 10 statute miles. The temperature was 25°C, and the dew point was 13°C. The altimeter setting was 30.18 inches of mercury.

The airplane was examined at the scene by an FAA aviation safety inspector. Examination revealed that the rudder and the tail structure just forward of the rudder were substantially damaged. The right main landing gear wheel pant was removed, and examination revealed that the tire and the innertube had each rotated independently of each other on the rim, and that the innertube valve stem was severed.

The pilot reported no deficiencies with the handling and performance of the airplane. The only mechanical malfunction/failure cited by the pilot was, "Right main tire lost all pressure."

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On June 26, 2017, at 1400 eastern daylight time, an experimental amateur-built Vans RV-10, N865HB, was substantially damaged during a runway excursion after landing at Blairsville Airport (DZL), Blairsville, Georgia. The airline transport pilot and a passenger were not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which departed Lumpkin County-Wimpys Airport (9A0), Dahlonega, Georgia about 1345 and was conducted under the provisions of 14 Code of Federal Regulations Part 91.

According to the pilot, he completed a landing to runway 26, retracted the flaps, and applied takeoff power to complete a touch-and-go landing. The nose turned to the right, the pilot corrected with a left rudder application, but the airplane continued to the right. The pilot reduced engine power, aborted the takeoff, and applied left braking but the airplane continued to the right, departed the runway, and travelled through a "depression" before coming to rest. As the main landing gear dropped into the depression, the tail section struck the ground which substantially damaged the tail structure.

The pilot held airline transport, flight engineer, flight instructor, and private pilot certificates with ratings for airplane single engine, multiengine, and rotorcraft helicopter. His most recent Federal Aviation Administration (FAA) first-class medical certificate was issued May 9, 2017. He reported 21,000 total hours of flight experience of which 100 hours was in the accident airplane make and model.

Aircraft Damage: Substantial
Defining Event: Fuel starvation

Analysis 

The private pilot topped off the airplane's four fuel tanks (20 gallons each, 18.5 of which was usable) before the estimated 2 hour 20 minute flight. He departed with the left main fuel tank selected and switched to each of the other three tanks for about 30 minutes each before turning the selector back to the left main tank for the remainder of the flight. About 20 minutes after switching back to the left main tank, the engine experienced a total loss of power. The pilot reported that the airplane would not maintain altitude, so he focused on making a forced landing and did not use the emergency checklist (which included switching to another fuel tank) to restart the engine. The airplane stalled right before touchdown and landed hard, which resulted in substantial damage to both wings and the fuselage.

Postaccident examination of the airplane revealed that the left main fuel tank was intact and empty. The left auxiliary fuel tank was breeched, and a small amount of fuel was found in the tank. The right-wing fuel tanks were not compromised, and about 13 gallons of fuel were drained from the auxiliary tank and about 11.5 gallons were drained from the main tank. Although a fuel supply line to the fuel manifold was found loose during postaccident examination, no fuel stains were observed on the attaching b-nut, fire sleeve, or surrounding area. Based on the condition of the b-nut and lack of stains surrounding the b-nut, the fuel supply line was likely not loose before the accident.

During a postaccident engine test-run, the b-nut was correctly installed, and the engine started immediately and ran without hesitation. Examination and the test-run of the engine revealed no evidence of any preaccident mechanical malfunctions or failures that would have precluded normal operation. Given that the pilot was operating the airplane on the left main fuel tank at the time the engine lost power and that the tank was found empty, the loss of engine power was likely due to fuel starvation, which resulted from the pilot's mismanagement of the fuel. The pilot's failure to use the emergency checklist and select a different tank when the loss of power occurred contributed to the accident.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's inadequate fuel management, which resulted in a total loss of engine power due to fuel starvation. Contributing to the accident was the pilot's failure to use the emergency checklist to restart the engine.

Collision with terr/obj (non-CFIT)

On June 24, 2017, about 1300 central daylight time, an Aero Commander 200D, N929DM, sustained substantial damage during a forced landing while approaching Northwest Florida Beaches International Airport (ECP), Panama City, Florida. The pilot and the passenger sustained minor injuries. The airplane was registered to a private company and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed, and the flight was operated on an instrument flight rules flight plan. The flight originated from the Malden Regional Airport (MAW), Malden, Missouri, about 1030.

The pilot stated that he topped off the airplane's four fuel tanks (20 gallons each, 18.5 gallons usable) prior to the estimated 2 hour and 20-minute flight. He started the engine, taxied, and took off on the left main fuel tank and climbed to 7,000 ft mean sea level (msl), burning about 18 gph. When he leveled off at 7,000 ft msl, he set engine power to a 15.5 gph fuel burn rate. The pilot said he had to deviate around weather but used a stop watch to remind him to switch tanks every 30 minutes, which he said he did during the entire flight. He cycled from the left main tank over to the left auxiliary tank after he leveled off at 7,000 ft msl. He then switched to the right auxiliary tank, then the right main tank, before switching back to the left main fuel tank for the remainder of the flight. About 20 minutes after switching to the left main tank, the engine lost power when he was five miles from the airport at an altitude of about 2,000 ft mean sea level (msl) (about 1,930 above ground level).

The pilot said the "engine was still running but not producing hardly any power, if any" and he was unable to maintain altitude, so he prepared to make a forced landing on a highway. During this time, he adjusted the mixture control and brought the throttle full forward, but to no avail. The pilot said he did not turn on the auxiliary fuel boost pump or switch fuel tanks as per the emergency checklist, and instead focused on trying to make a safe landing in a clearing between a set of power lines and a forest. He also thought he had about 20 minutes of fuel remaining in the left tank and did not consider the loss of power to be fuel related.

The airplane stalled right before touchdown and landed hard on the right main landing gear. The pilot said the engine lost complete power before touchdown. The airplane skidded, turned around and came to rest upright on a southwesterly heading resulting in substantial damage to both wings and the fuselage.

A postaccident examination of the airplane revealed that the left main fuel tank was intact and absent of fuel. The outboard section of the left wing, that housed the left auxiliary fuel tank, was bent up and partially separated. A small amount of fuel was observed in the left auxiliary tank and a sheen of fuel was observed under this portion of wing when it was recovered. The right wing also sustained impact damage, but the fuel tanks were not compromised. About 13 gallons of fuel were drained from the right wing auxiliary tank and about 11.5 gallons were drained from the right main tank.

Postaccident examination of the engine revealed it had sufficient oil and the spark plugs exhibited normal wear as per the Champion Check-A-Plug chart. An internal inspection of each cylinder via a lighted borescope revealed each of the cylinder's valves were intact and exhibited normal combustion deposits. The engine was rotated via manual rotation of the propeller and valve train continuity and thumb-compression were established on each cylinder. The spark plugs were re-installed, and the engine was prepped to be test-run on the airframe utilizing the airplane's own fuel system.

About 5-gallons of fuel were placed in the left main fuel tank and no leaks from the tank or its associated plumbing were observed. However, in preparation to start the engine, when the electrical fuel boost-pump was turned on to pressurize the fuel system, fuel sprayed from the b-nut that connected the main fuel supply line to the fuel manifold fitting. The b-nut was cross-threaded on the fitting and connected by about three threads. The fuel supply line was loose and not properly seated to the fitting. About six threads on the fitting were exposed, of which, two of the threads were shiny (clean) in appearance and the other four were dark from exposure to dirt and oil. There was no anti-tamper putty observed on the b-nut and fitting. No fuel stains were observed on the b-nut, fire sleeve, or surrounding area. The b-nut was tight on the fitting and had to be removed using a wrench. The b-nut was re-installed, and the engine started immediately and ran through its entire power-band without hesitation.

A review of the maintenance logbooks revealed the last annual inspection on the engine was performed on September 13, 2016, at a total time of 774.78 hours. At the time of the accident, the engine had accrued about 25.22 hours since the annual inspection. The airplane's last annual inspection was completed on February 2, 2017, at a total time of 2,850.68 flight hours.

The pilot held a private pilot certificate with ratings for airplane single-engine land, and instrument airplane. His last Federal Aviation Administration (FAA) third-class medical was issued on September 11, 2015. The pilot reported a total of 252.2 flight hours, of which, 20.2 hours, were in the accident airplane.

The weather conditions reported at ECP at 1328 included wind from 220 degrees at 8 knots, gusting to 18 knots, visibility 10 miles, scattered clouds 2,900 ft, broken clouds 3,800 ft, temperature 30° degrees C, dewpoint 23° C, and a barometric altimeter setting of 30.04 inches of mercury. The field elevation at ECP is 64 feet msl.

Per the airplane's Owner's Manual, page 4-2, ENGINE FAILURE, it states, "Should engine failure occur, the first step in any procedure is to lower the nose, set up and maintain a safe flying airspeed. Some of the most probable causes of engine failure are: fuel starvation, ignition malfunction, loss of oil and engine seizure. Some of the symptoms usually appear prior to complete engine failure. 

If the engine shows a decrease in power, starts running rough, or completely loses power, perform the following check:

1) Check that the fuel selector is on a usable tank. If necessary to switch tanks, retard the throttle, switch to desired tank.

2). Turn fuel boost pump "ON", advance throttle slowly until power is regained, and then turn OFF fuel boost pump.

3). Place mixture full rich and then lean to altitude if necessary.

4) Check ignition switch to "BOTH" position

5) Check all engine instruments.

On June 24, 2017, about 1300 central daylight time, an Aero Commander 200D, N929DM, sustained substantial damage during a forced landing while approaching Northwest Florida Beaches International Airport (ECP, Panama City, Florida. The pilot and the passenger sustained minor injuries. The airplane was registered to a private company and operated by the pilot as a 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed and the flight was operated on a visual flight rules flight plan. The flight originated from the Malden Regional Airport (MAW), Malden, Missouri, about 1030.

The pilot stated that he was on a 5-mile final for runway 16 at an altitude of about 2,000 ft mean sea level (msl), when he heard a "muffled bang" come from the engine. The engine then lost partial power. The pilot said he turned off the autopilot, trimmed for best glide, and prepared to make a forced landing on a highway since he knew he would be unable to make the runway. During this time, the pilot adjusted the mixture control to troubleshoot the problem and brought the throttle full forward, but to no avail. The pilot said he did no turn on the auxiliary fuel boost pump or switch fuel tanks, and instead focused on trying to make a safe landing.

The pilot stated that the airplane descended quickly and he ended up landing in a clearing between a set of power lines and a forest. The airplane stalled right before touchdown and landed hard on the right main landing gear. The airplane skidded, turned around and came to rest upright on a southwesterly heading. The pilot said that he recalled hearing "silence" just prior to touchdown and believes that the engine had stopped producing power before impact.

A review of on-scene photographs revealed that both wings and the fuselage were substantially damaged. The wreckage was retained for further examination.

The weather conditions reported at ECP at 1328 included wind from 220 degrees at 8 knots, gusting to 18 knots, visibility 10 miles, scattered clouds 2,900 ft, broken clouds 3,800 ft, temperature 30° degrees C, dewpoint 23° C, and a barometric altimeter setting of 30.04 inches of mercury.
