Aviation Accident Factual Report - National Transportation Safety Board

Location: Farmerville, LA
Accident Number: CEN17FA281
Date & Time: 07/23/2017, 1715 CDT
Registration: N8661S
Aircraft: CESSNA 150F
Aircraft Damage: Substantial
Defining Event: Low altitude operation/event
Injuries: 1 Fatal
Flight Conducted Under: Part 91: General Aviation - Personal 

On July 23, 2017, about 1715 central daylight time, a Cessna 150F airplane, N8661S, impacted the waters of Lake D'Arbonne while maneuvering near Farmerville, Louisiana. The airline transport pilot was fatally injured. The airplane sustained substantial damage. The airplane was registered to and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed in the area about the time of the accident, and the flight was not operated on a flight plan. The local flight originated from the Union Parish Airport, near Farmerville, Louisiana, at an unknown time.

A witness who had a house on the lake and knew the pilot reported that the pilot initially flew over the lake in a Piper airplane. According to the witness, the pilot called the witness from the Piper and said that he was returning to the airport to try to get the engine of his Cessna 150 (the accident airplane) to start. The pilot told the witness that he had the Cessna 150's battery on charge at the time. The witness reported that the pilot subsequently made a few passes in the Cessna 150 around the lake in front of the house. The witness reported hearing the engine "sputter" on the final pass and seeing the airplane "wobble from side to side" while it was flying at a low altitude over the lake. The witness said, "It looked like he was attempting to land on water but knew that he was too fast. He gave the engine some throttle and looked like he attempted to climb, but the left tire hit the water and [it] caused the plane to flip into the water."

Another witness at the lake saw the airplane make a low pass over the lake from south to north. He reported that the airplane flew "lower and lower," and the airplane's nose wheel impacted the lake while the airplane was in a slightly nose-down attitude. The witness then saw a wing tip impact the water, and the airplane subsequently nosed over. He reported that he heard the engine running throughout the low pass.

A third witness who lived at the lake reported that he heard and saw the airplane make several low passes over the lake. He said that on its last pass, the airplane was level about 5 to 10 ft above the surface. It made a slight pitch up and then back down; the left main gear and left wing contacted the water, and the airplane cartwheeled. This witness said that the pilot was friends with one of his neighbors and had conducted numerous low passes over the lake during the previous 4 years.

The accident airplane was recovered from the lake using a nearby boat ramp. Blight was observed on grass in the ramp area where the airplane was recovered. Protruding stumps were present at multiple locations where the airplane was reported to have impacted. The airplane was subsequently relocated to a secured yard to be examined.

An examination of the wreckage revealed that the left wing forward spar was fractured near the aileron/flap junction. An outboard section of the left wing exhibited rearward compression damage and was bent upward. This section was observed resting on top of the inboard section of the left wing. An outboard section of the left aileron was separated from the left wing and was not recovered with the wreckage. The remaining section of the inboard left aileron remained attached to the left wing. The left flap remained attached to the left wing and was in the fully retracted position. Both left and right plastic wing tips were not recovered.

The right wing remained attached to the airframe. The right aileron and right flap remained attached to the wing. The right flap was in the fully retracted position. An outboard section of the right wing exhibited rearward compression damage near its wing tip. A section of the outboard right wing and leading edge skin was separated from the wing.

The empennage was separated from the fuselage aft of the rear window and remained attached to the fuselage by the flight control cables and stringers. The horizontal stabilizer and elevators remained attached and did not exhibit any damage. The vertical stabilizer and rudder remained attached and were intact. The rotating beacon was intact.

All the flight control cables were intact and control cable continuity was established for all flight control surfaces. The upper portions of the pilot's and passenger's 3-point, dual shoulder harness restraint systems were found intertwined. First responders reported to the FAA that the pilot was wearing the lap belt portion of the restraint system. The tachometer indicated 726.2 hours at the time of the postaccident examination. Pressurized air was applied to the fuel line at the firewall and the sound of the escaping air was heard at both fuel tank filler necks, consistent with the fuel selector valve being in the "ON" position.

The engine was found separated from its airframe. The carburetor was separated from the engine at its intake mounting flange. All other observed accessories remained attached to the engine. The propeller remained attached to the crankshaft propeller flange. Both propeller blades were bent forward. However, one blade was bent forward more than the other blade.

The top spark plugs were removed and an examination of the inside of the cylinders using a lighted borescope revealed normal piston, valve, and cylinder bore signatures. During the rotation of the propeller, all cylinders displayed good thumb compression and suction. The valves and rocker arms were noted to operate normally while the propeller was rotated. All spark plug electrodes displayed normal operating and wear signatures when compared with a Champion Aviation Service Manual AV6-R chart.

The right magneto remained attached to its installation point and was undamaged. During propeller rotation, its impulse coupling operated and it could be heard operating at the same time as the left magneto's impulse couplint. During impulse coupling operation, the right magneto produced a spark at all four towers. The left magneto remained attached to its installation point and was undamaged. During propeller rotation, its impulse coupling was noted to operate and could be heard operating at the same times as the right magneto's impulse coupling. However, during impulse coupling operation, the left magneto did not produce a spark at any of the towers. The left magneto was removed from its mounting point and water was drained from the magneto. The magneto drive was spun using a drill, and the magneto produced a spark at all four towers.

The vacuum pump produced a suction as the propeller was rotated by hand. Disassembly of the carburetor revealed that the floats were intact and that the needle valve operated. No debris was found in the fuel screen and no preimpact anomalies were detected during the carburetor disassembly. 

Medical And Pathological Information

The Union Parish Coroner's Office performed an autopsy on the pilot and collected toxicological samples. The autopsy listed the cause of death as blunt force head injuries with drowning. The autopsy indicated that hypertensive atherosclerotic cardiovascular disease was present.

The FAA's Bioaeronautical Sciences Research Laboratory performed toxicology tests of samples from the pilot, which were negative for carbon monoxide, ethanol, and tested drugs.

Tests And Research

A portable Garmin GPS 295 found in the wreckage was shipped to the National Transportation Safety Board Recorder Laboratory (NTSB). The GPS 295 is capable of storing waypoints, routes, and detailed tracklogs in non-volatile memory. Tracklog storage may be activated or de-activated at the user's discretion. The unit contains hardware and software that permits the download of recorded waypoint, route, and tracklog information.

An NTSB recorder specialist examined the GPS unit and determined that it did not contain any data in reference to the accident flight. However, the GPS unit did contain recorded data for previous flights where an airplane flew near the accident location. The Global Positioning System Device Specialist's Factual Report is included in the docket material associated with this investigation.

On July 23, about 1715 central daylight time, a Cessna 150F airplane, N8661S, while descending over Lake D'Arbonne, impacted the lake and nosed over. The airline transport pilot, who was the sole occupant, was fatally injured. The airplane sustained substantial fuselage and wing damage during the nose over. The airplane was registered to and operated by the pilot as a 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed in the area about the time of the accident, and the flight was not operated on a flight plan. The local flight originated from the Union Parish Airport, near Farmerville, Louisiana, at time unknown.

A witness at the lake that knew the pilot saw the accident airplane flying. The witness stated that the pilot's first pass by the witness's house was in a Piper airplane. The pilot called from the Piper and said that he was going back to try and get the Cessna 150 started. The pilot stated that he had the Cessna 150 battery on charge at the time. The pilot made a few passes in the Cessna 150 around the lake in front of the house. The witness reported hearing a "sputter" on the last pass. The witness stated that the airplane "wobbled" from side to side and noticed the airplane was flying low. The witness said, "It looked like he was attempting to land on water but knew that he was too fast. He gave the engine some throttle and looked like he attempted to climb, but the left tire hit the water and It caused the plane to flip into the water."

Another witness at the lake stated that he saw the airplane fly lower and lower over the lake. The airplane flew from south to north. The airplane's nose wheel impacted the lake while the airplane was in a slightly nose down attitude. The witness saw a wing tip impact the water and the airplane subsequently nosed over. He reported that he heard the engine running during the flight and at the time of the accident.

The 73-year old pilot held a Federal Aviation Administration (FAA) airline transport pilot certificate with a multi-engine land rating. He held commercial pilot privileges for single engine land airplanes. The pilot held an FAA first-class medical certificate that was issued on June 29, 2017, with a limitation: Must wear corrective lenses. On the application for that medical certificate, the pilot reported that he had accumulated 16,870 hours of total flight time and 60 hours in the six months prior to the medical certificate. An initial review of his logbook revealed that he had accumulated 16,722.8 hours of total flight time.

Why the hell are so many accidents with death happening in the GA community? So many experienced pilots with thousands of hours dying for no reason. Especially ATP's. WHY?
