Injuries: 1 Fatal
Flight Conducted Under: Part 91: General Aviation - Personal 

On April 15, 2018, at 2054 eastern daylight time, a Cessna 525, N525P, was destroyed after it impacted terrain near Crozet, Virginia. The private pilot was fatally injured. The airplane was owned by a private individual and was being operated under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91 as a personal flight. Night instrument meteorological conditions prevailed at the time of the accident, and no flight plan was filed for the flight, which departed Richmond Executive–Chesterfield County Airport (FCI), Richmond, Virginia, about 2035 and was destined for Shenandoah Valley Regional Airport (SHD), Weyers Cave, Virginia.

According to a friend of the pilot, the pilot had "a couple of drinks" while they were preparing dinner. The pilot left her home about 1930. The pilot's friend thought that the pilot would be going to a hotel because it was getting dark, but FCI security video showed that the pilot arrived at the airport at 2002 and walked to the airplane at 2004. The pilot then walked around the airplane for about 3 minutes, boarded the airplane, closed the main cabin door, and initiated the engine start sequence at 2017. About 2 minutes later, the airplane began to taxi to the departure end of runway 15 and then taxied back to the departure end of runway 33. The takeoff roll began on runway 33 at 2033. The airport security video showed the windsock, which indicated that the wind favored a departure from runway 15. According to an airport line service employee, the airplane departed with a tailwind. The employee also stated that the pilot did not communicate on the Unicom frequency.

According to air traffic control data provided by the Federal Aviation Administration (FAA), a radar target identified as the accident airplane departed FCI and reached a maximum altitude of about 11,500 ft mean sea level (msl) at 2040. The airplane then began to descend and, at 2044, leveled off at an altitude of about 4,300 ft (which was below the minimum safe altitude of 5,700 ft msl for SHD). The airplane remained at 4,300 ft until 2053, when it began a descending left turn. The last two radar returns were 5 seconds apart and showed the airplane at 3,300 ft and 2,800 msl, which indicated that the airplane was descending about 6,000 ft per minute. Radar contact was lost at 2054. Throughout the flight, the pilot did not have any contact with air traffic control.

According to a witness near the accident location, he heard the "screaming of the engines" and then felt the terrain shake when the airplane impacted the ground. He stated that, at the time of the accident, the cloud ceiling was "really low," the winds were moderate, and heavy rain was occurring.

Latitude, Longitude: 38.097778, -78.722500 

The airplane impacted three 40-ft trees about 15 ft before impacting terrain at an elevation of 1,520 ft msl. The impact location was about 450 ft from the last radar return. The initial impact crater was about 4 ft deep, and a scent similar to Jet A fuel was noted at the accident site. The airplane was highly fragmented, with all major components of the airplane located at the accident site. The debris path emanated from a 120° heading, and the accident site was on a 25° incline.

All flight control cables and bellcranks remained attached in their appropriate locations and showed evidence of overstress failures.

The standby attitude indicator was located along the debris field and was disassembled. The gyro housing exhibited rotational scoring.

The left engine had separated due to impact forces and was located in the initial impact crater. The compressor turbine blades were damaged by the impact, and rotational scoring was noted on the blades. The turbine blade bases exhibited rotational scoring.

The right engine had separated due to impact forces and was located about 60 ft beyond the initial impact location. The engine was partially consumed by fire. The compressor fan blades exhibited rotational scoring, and several blades were bent forward. In addition, the compressor turbine blade housing exhibited rotational scoring, and the blades were bent the opposite direction of travel. 

Medical And Pathological Information

The Commonwealth of Virginia Department of Health, Office of the Chief Medical Examiner, Richmond, Virginia, performed the autopsy of the pilot. The autopsy report indicated that the pilot died as a result of multiple blunt force injuries.

Toxicology testing performed at the FAA's Forensic Sciences Laboratory identified ethanol (0.080 gm/hg, which equates to 0.080 gm/dl) and cetirizine in the pilot's muscle tissue.

Ethanol is the intoxicant commonly found in beer, wine, and liquor. It acts as a central nervous system depressant and impairs judgment, psychomotor functioning, and vigilance. The effects of ethanol on aviators are generally well understood: it significantly impairs a pilot's performance, even at very low levels. Title 14 CFR 91.17(a) prohibits any person from acting or attempting to act as a crewmember of a civil aircraft while having 0.040 gm/dl or more ethanol in the blood. In addition, the regulation states that no person can act as a crewmember of an aircraft within 8 hours after the consumption of any alcoholic beverage. Ethanol can also be produced in body tissues postmortem.

Cetirizine is a sedating antihistamine available over the counter and by prescription. It carries this warning for patients: "when using this product…drowsiness may occur…avoid alcoholic drinks…alcohol, sedatives, and tranquilizers may increase drowsiness…be careful when driving a motor vehicle or operating machinery."

Additional Information

FAA Airplane Flying Handbook

The handbook provided the following information about an airplane's attitude and spatial disorientation:

The pilot must believe what the flight instruments show about the airplane's attitude regardless of what the natural senses tell. The vestibular sense (motion sensing by the inner ear) can and will confuse the pilot. Because of inertia, the sensory areas of the inner ear cannot detect slight changes in airplane attitude, nor can they accurately sense the attitude changes that occur at a uniform rate over a period of time. On the other hand, false sensations are often generated, leading the pilot to believe the attitude of the airplane has changed when, in fact, it has not. These false sensations result in the pilot experiencing spatial disorientation.

Aircraft: Piper PA60
Aircraft Damage: Destroyed
Defining Event: Aerodynamic stall/spin
Injuries: 3 Fatal
Flight Conducted Under: Non-U.S., Non-Commercial 

On July 30, 2018, about 1044 eastern daylight time (EDT), a Piper PA-60-602P, Canadian registration C-GRRS, was destroyed when it impacted terrain while attempting to land at Greenville Airport (3B1), Greenville, Maine. The foreign-certificated pilot and two passengers were fatally injured. The airplane was registered to and operated by the pilot under Canadian Aviation Regulations as a recreational flight. Visual meteorological conditions prevailed at 3B1 at the time of the accident, and an instrument flight rules flight plan was filed for the flight, which departed Pembroke Airport (CYTA), Pembroke, Ontario, Canada, about 0905, and was destined for Charlottetown Airport (CYYG), Prince Edward Island (PEI), Canada.

According to the CYTA airport manager, the pilot had been a regular customer at the airport for several years. The pilot flew the accident airplane into CYTA 3 days before the accident and purchased 117 gallons of 100LL fuel. The airport manager, who personally fueled the airplane that day, said that he topped off the wing tanks first, followed by the center tank. He did not fuel the auxiliary tank. The manager said that each of the fuel caps felt tight and he made sure they were properly fitted back onto each tank. The airplane was then placed in a hangar until the morning of the accident.

A review of air traffic control communications revealed that, after departure, the airplane climbed and leveled off at 23,000 ft mean sea level (msl) and the pilot contacted the Boston Air Route Traffic Control Center at 1019:39. About 13 minutes later, the pilot told the controller, "...we're losing altitude trying to figure out what's going on." The controller then began to vector the airplane toward 3B1, which was about 17 miles southeast. At 1033, the controller asked the pilot, "...are you producing power right now or have you lost power." The pilot responded, "I think I've lost power..." The controller asked the pilot if he could make Greenville Airport, and the pilot responded, "Ah I think so."

The controller continued to vector the pilot to 3B1 and declared an emergency on his behalf. At 1040:41, the pilot reported that he had the airport in sight and was going to join the downwind leg of the traffic pattern for runway 14. Radar data indicated that the airplane was at an altitude of about 4,600 ft msl at this time. The airplane continued to descend as it turned onto the base and final legs of the traffic pattern for runway 14. At 1043:32, said the pilot transmitted, without a call sign, "I gotta turn around and ahh we're a little high obviously." About this time, the airplane was on a short final for runway 14 at an altitude of about 1,800 ft msl (about 400 ft above ground level). The airplane then entered a left turn to the northwest and was over the airport when radar contact was lost at 1043:48.

A witness was standing on the airport's apron near the terminal building between runway 14 and 21 when he first saw the airplane approaching the airport from the south. The witness said the airplane was "low." It flew over the center of the airport and made what appeared to be a left downwind entry for runway 21. There was no smoke trailing the airplane and the landing gear was retracted. The witness said both propellers were turning, but he could not tell how fast they were turning or if one was turning faster than the other. He was standing next to active construction equipment at the time, which prevented him from fully hearing the engines. When the airplane reached the approach end of runway 21, it began a "shallow" left turn. The nose of the airplane was "high" and the airplane was "going so slow." He said, "It was like it almost stopped in the air" before the left wing suddenly dropped and the airplane dove toward the ground and disappeared behind an embankment. The witness saw a debris cloud and knew that the airplane had crashed.

A second witness, who was a commercial pilot, was standing in front of a hangar on the southeast side of runway 3/21 when he saw the airplane approaching the airport from the west. Instead of landing on runway 14, the airplane continued to fly over the center of the airport. The witness said that the airplane flew directly over him as it made a left turn and flew parallel to runway 3/21. He stated that both propellers were turning, and the engines were producing power; however, he could not estimate an engine speed. He said the airplane was not gliding because it maintained its altitude. The witness could not recall if the landing gear or flaps were extended but recalled that the belly of the airplane was painted black. When the airplane approached the end of the runway, it began a "shallow" left turn and was flying "really slow." The bank angle continued to increase to a point where he could see the entire top of the airplane. The airplane then pitched up and appeared to momentarily "stop" before the left wing "stalled" and the nose pitched down toward the ground. The witness did not hear any increase in engine noise before the impact. He also said that he did not believe the pilot was trying to land on runway 21 because he was positioned "way too close" to the runway.

The airplane came to rest in field about 100 yards from the approach end of runway 21 on a magnetic heading of 220°. All major components of the airframe were accounted for at the site and there was no post-impact fire. The wreckage was contained to where it impacted the ground. The nose and forward fuselage area were compressed aft from impact; both engines were partially buried in the ground, and the empennage was compressed and twisted to the left. The tail section appeared undamaged and was twisted to the left. Both wings remained attached to the airframe at the wing root and sustained impact damage.

Both wing fuel tanks were breached, but the fuel finger screens in both tanks were absent of debris. The center fuel tank (bladder-type) was breached, and the auxiliary fuel tank remained in the airplane but was breached. According to first responders, about 20 gallons of fuel was recovered from the site. The vegetation forward of the wreckage displayed fuel blighting. The fuel selector handles were impact damaged and their position could not be determined. Continuity of the fuel system from the wings to the center fuel tank was established. The center sump was filled with 100LL fuel and the screen was absent of debris. The Nos. 1 and 4 fuel shutoff valves were in the "Open" position, and the Nos. 2 and 3 cross-feed valves were in the "Closed" position.

The left and right fuel boost pumps were located and the main fuel line to each pump was separated from impact. Fuel was observed draining from each pump. Each pump was tested on a 24-volt battery and both pumps were functional. The left and right main fuel tank filters were removed and disassembled. Both were absent of debris.

The flight controls were heavily fractured, but control continuity was established for the elevator and rudder to mid-fuselage. Both flight control wheels were broken off from impact; but the control column and linkages for the control yoke and rudder pedals were observed in the cockpit area. Both left and right seat rudder pedals, and the outboard rudder pedal for the right seat remained attached to their respective linkages. The right seat inboard rudder pedal had separated. Continuity to mid-cabin was established for the left- and right-wing flaps and ailerons. The left flap actuator appeared fully extended, and the right flap actuator was near the fully-retracted position.
The rudder trim was neutral, and the elevator trim was consistent with one-quarter nose-up trim. The landing gear selector handle in the cockpit was impact damaged but appeared to be in the retracted position. The left main gear remained attached to the left wing and the right main gear had separated. The nose wheel was under the fuselage and the tire had separated.

The cockpit area sustained extensive impact damage, with more of the damage occurring to the left (pilot) side area. The throttle levers were positioned between mid- and full power and bent to the left. Both propeller levels were full forward. Both mixture control handles were full forward and bent to the right. The flap selector handle was in the fully extended position.

The left engine remained attached to the airframe by the engine mount and sustained moderate impact damage. Visual examination of the engine revealed no obvious evidence of pre-impact mechanical malfunction or fire.

The propeller was removed to facilitate the examination. The top spark plugs and the vacuum pump were removed, and the crankshaft was rotated by hand via the vacuum pump drive spline. The crankshaft rotated freely, and compression and valve train continuity were established to each cylinder and to the accessory section. The combustion chamber of each cylinder was examined through the spark plug holes utilizing a lighted borescope; no anomalies were observed. The bottom spark plugs were removed and examined along with the top spark plugs.

Each engine was equipped with a Hartzell three-bladed propeller. Both propellers remained attached to their engine crankshaft mounting flanges during the impact sequence. Both propeller spinner domes were crushed, torn and partially formed around the hub area. Both propeller assemblies displayed packed dirt in the spinner and around the hub components.

Examination of the left propeller revealed that the left hydraulic unit separated from the hub unit and was crushed but remained attached to the propeller assembly via the pitch change rod. The pitch change rod was cut by a hacksaw to remove the feathering spring danger and facilitate propeller removal from the engine. One of the counterweights was also removed to facilitate cutting the pitch change rod. The left and right propeller blades had similar damage; two blades were bent aft and twisted towards low pitch. The bending on the third blade was slightly forward and twisting was unremarkable. The propeller mounting flange and hardware appeared intact. The blades appeared to be at a low pitch angle.

There was distinguishable chordwise/rotational scoring on the cambered side of the blade near the leading edges. There was also leading-edge gouging with material deformation toward low pitch. All three pitch change knobs were fractured, and the associated preload plates had damage indicating forceful rotation towards low pitch.

Examination of the right propeller revealed two blades were bent aft and twisted towards low pitch. The bending and twisting on the third blade appeared unremarkable. The hydraulic unit separated from the hub unit threads and the cylinder was buckled/bent to one side. The R2 blade retention pocket was fractured in a helical path direction suggesting rotation. The propeller mounting flange and hardware appeared intact. The blades appeared to be at a low pitch angle.

There was distinguishable chordwise/rotational scoring on the cambered side of the blade near the leading edges. There was also leading-edge gouging with material deformation towards low pitch. Two of the three pitch change knobs were fractured, and the associated preload plates had damage indicating forceful rotation toward low pitch. The low pitch stops also displayed an impact mark indicating the pitch change mechanism was forced in the low pitch direction during impact.

All propeller components were accounted for at the point of impact with terrain. There were no discrepancies noted that would prevent or degrade normal propeller operation prior to impact. All damage was consistent with high impact forces.

The damage observed to both propellers indicated power symmetry at the time of impact. Chordwise/rotational scoring on the cambered side of the blade and leading-edge gouging were consistent with rotation at the time of impact and suggested a low/idle power condition. Internal impact marks indicated that the propeller blade angle was in the low range of normal operation during the impact sequence and was forcefully rotated towards low pitch.

No mechanical discrepancies were noted with either engine or their respective propeller system that would have precluded normal operation at the time of impact.

The airplane was equipped with a JPI EDM-760 engine data monitor and a Shadin Fuel Flow Indicator. The Shadin unit sustained extensive impact damage. The non-volatile memory device was removed and installed in a laboratory surrogate indicator. Upon applying power, only error messages were displayed.

The JPI EDM-760 sustained extensive impact damage but contained data from the accident flight. The duration of the recording was about 1 hour and 50 minutes. The unit recorded time with the first data sample based on the unit's internal clock, which was set and updated by the operator. The time on this unit appeared to be EDT and was about 12 minutes ahead from the actual time of the accident. The downloaded parameters included battery voltage, engine exhaust gas temperature (EGT), and cylinder head temperature (CHT) for both engines. There were no parameters for fuel pressure or fuel flow. A review of the recorded data revealed that, about 1030, there was a jump followed by a decrease in EGT and CHT temperatures for both engines. The temperatures decreased for about 9 minutes, during which time the right engine EGT data spiked twice. Both engine's EGT and CHT temperatures returned to normal, consistent with both engines producing power, for the remaining 5 minutes of flight before the data ended about 1044.

Medical And Pathological Information

An autopsy of the pilot was conducted by the Office of Chief Medical Examiner, Augusta, Maine, on July 31, 2018. The cause of death was determined to be "extensive blunt force trauma."  Toxicological testing performed by the FAA's Forensic Sciences Laboratory was negative for ethanol and drugs.

Fatal accident occurred March 25, 2020 at Treasure Coast International Airport (KFPR), Fort Pierce, St. Lucie County, Florida

Chon Rodriguez


FORT PIERCE, Florida — A construction worker installing insulation on a new hangar at Treasure Coast International Airport died in an accident.

Chon Michael Rodriguez, 49, of Saginaw, Michigan, died when he fell 60 feet from the structure Wednesday afternoon at 3191 Jet Center in Fort Pierce, according to an incident reported released by the St. Lucie County Sheriff's Office on Thursday.

The victim was wearing a safety harness and was found lying face down unresponsive, according to the report. After attempted to render aid, the St. Lucie Fire Department declared him dead 15 minutes after responding at 1:32 p.m.

A witness Martin Cuellar-Gomez told a detective that he and Rodriguez were on the roof about 45 feet apart laying insulation when a gust of wind blew, and Gomez turned around and Rodriguez was no longer on the roof.

A representative with the Occupational Safety and Health Administration arrived to conduct an investigation into the incident.

A GoFundMe page said Rodriguez was an ironworker from Saginaw, Michigan.

St. Lucie County is investing more than $19 million in the Treasure Coast International Airport and Business Park, including work on a new hangar, according to the county website.

The new hangar is designed to house a 737 or A320and an Embraer 175 undergoing maintenance activities at the same time. It will be as tall as the air traffic control tower.

The last new hangar was constructed in 2008.

The airport had commercial service until March 2019 when commuter airline Fly the Whale offered service to Tallahassee.

Earlier this month, the Federal Aviation Administration said the county needs to fix a crumbling runway, add lighting and new signs, and mow the grass along the shoulder of runways before it can resume offering commercial service, TCPalm reported.
