Probable cause
the pilot's improper flare and improper recovery from a bounced landing, which resulted in overload failure of the nose gear and a nose over. Factors associated with the accident were: the pilot's failure to follow procedures and directives by neglecting to tie down and secure the load, and his failure to ensure that the passengers had seatbelts available and utilized them.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The airplane landed hard and bounced into the air. During the subsequent touchdown, the nose wheel separated, and the airplane nosed over onto its back. Metallurgical examination of the nose wheel strut and forks revealed overstress fractures. The cargo was not secured, and struck the back seat passenger during the nose over. The aft passenger sustained serious neck injuries. The cargo was loaded on top of the aft seatbelts, making them unavailable to the aft passenger. The front seat, pilot-rated, passenger did not use the available lap belt or shoulder harness.
Factual narrative
On September 1, 1997, about 1630 Alaska daylight time, a Cessna U206E airplane, N9129M, was substantially damaged when it nosed over during landing at the Tatitna landing strip, seventy three miles east of McGrath, Alaska. The airline transport certificated pilot was uninjured. The front seat passenger sustained minor injuries. The back seat passenger sustained a serious neck injury.
The airplane was operated by Alaska Air Taxi, of Anchorage, Alaska. The flight was conducted under 14 CFR Part 135 as an on demand air taxi from Anchorage to the Tatitna strip. The flight departed Lake Hood strip at 1530. Visual meteorological conditions prevailed at the time of the accident, and a company flight plan was filed.
The pilot said that upon landing, the nose gear collapsed and the airplane nosed over onto its back.
Witnesses on the ground, and the passengers, observed the airplane land hard and bounce into the air. The passengers said the airplane bounced twice, and on the third touchdown, nosed over. Both passengers stated that the landing was slightly downwind.
The engine and empennage both separated from the airplane.
The nose landing gear assembly had been installed on the airplane twelve days prior to the accident. Inspection of the nose wheel, strut, and forks, revealed permanent deformation to the left. Further microscopic inspection of the failed components at the NTSB metallurgical laboratory revealed fractures typical of right to left overstress. A small region of fatigue was observed at the forward bolt hole of the right fork.
Neither passenger had their seatbelt fastened. Both passengers said that the cargo was not restrained, and had been placed on top of the rear seat passenger's lap belt, and that there was no belt available for the rear seat occupant. The passenger seated in the right, front seat said that his belt and shoulder harness were both available, but he did not wear them. During the accident sequence, the cargo struck the rear seat passenger.
