Aircraft involved
Probable cause & findings
The pilot's failure to maintain aircraft control and the subsequent inadvertent stall/spin to the ground. Contributing factors were the inadequate preflight by the pilot, and the airplane's fuel contamination by water.
Factual narrative
On February 16, 2006, at approximately 0815 Pacific standard time, a Cessna 150, N5611E, was substantially damaged upon impact with terrain following a loss of engine power on takeoff at Port Elsner Airport, White Salmon, Washington. The airline transport pilot, the sole occupant of the airplane, was seriously injured. The pilot/owner was operating the airplane under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the personal flight which was originating at the time the accident. The pilot had not filed a flight plan. A witness, who was hiking in the area, said she heard a loud engine noise and turned to see a bright yellow airplane taking off. Seconds later, the noise stopped, and she turned to see the airplane "crash." The pilot was critically injured with a broken eye socket, broken cheekbone, bruises on the brain, and possible broken vertebrae. The Klickitat County Sheriff's Deputy said that he arrived on scene approximately 30 minutes after the accident. He said "the temperature was below freezing, the sun was shining and a heavy layer of frost was on the ground. Frost was melting off the aircraft and water was dripping onto the ground." He said it had rained heavily the past several days and he was told that the airplane had been parked outside. On February 17, 2006, a Federal Aviation Administration (FAA) inspector and a representative of the airplane's manufacturer went to the scene and found the airplane approximately 500 feet west of the departure end of runway 17 of a private grass 1,600 foot long airstrip. They found the fuselage nose down with both wings bent forward and compression damage to both outboard leading edges. The right wing root attachment points had separated. The wing strut attachment points were secure. The empennage was broken aft of the cabin area, and rotated 90 degrees toward the right wing; the right horizontal stabilizer was holding the back portion of the fuselage off the ground. The aircraft was not equipped with shoulder harnesses. The airplane had an STC engine conversion to a Lycoming O-320, 150 horse power engine. Water was found in the carburetor and approximately 1-2 tablespoons of frozen water were found in the fuel strainer. Minimal rotational signatures were noted on the propeller. Due to the serious nature of the pilot's injuries, he was not interviewed and a written statement was never obtained. FAA pilot medical application records indicate that the pilot had more that 23,000 hours of flight experience.
