The pilot’s failure to maintain airplane control and improper recovery from an unusual attitude, which resulted in an in-flight breakup.
The pilot’s failure to maintain directional control on landing, which resulted in a runway excursion and subsequent nose-over. Contributing was the pilot’s lack of experience in the accident airplane.
Failure of the landing gear motor, which prevented the gear from extending fully to the down and locked position, which resulted in a gear collapse on landing and a subsequent loss of directional control.
The mechanic’s improper maintenance, which resulted in the crankshaft expansion plug dislodging in flight and a subsequent forced landing.
The airplane’s impact with a deer during takeoff.
The separation failure of a landing gear system hydraulic line and its compression fitting during cruise flight, which resulted in a partial gear up landing.
The pilot’s failure to use full power during takeoff and his delayed decision to abort the takeoff, which resulted in a runway overrun and subsequent impact with terrain.
The pilot’s decision to land at night without runway lighting, which resulted in a collision with an object.
Fuel starvation due to a fuel system leak, which resulted in a loss of engine power and the subsequent forced landing on unsuitable terrain.
The pilot’s failure to conduct a proper preflight inspection and ensure the fuel was uncontaminated, which resulted in a partial loss of engine power and forced landing.
The pilot’s failure to maintain clearance from an object during the takeoff ground roll due to inadequate monitoring of the environment.
The pilot’s failure to maintain terrain clearance after flying into the wrong canyon in mountainous terrain which resulted in a collision with trees and terrain.
