Probable cause: The failure of the landing gear through bolt primarily due to fatigue during a hard landing, which resulted in a landing gear collapse and runway excursion. Contributing to the accident was noncompliance with the manufacturer service letter.
Probable cause: The pilot’s inadvertent landing in snow adjacent to the snow-covered runway resulting in a collision with runway signs.
Probable cause: The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during the approach to land, which resulted in an aerodynamic stall.
Probable cause: The pilot’s failure to follow ground control instructions and to see and avoid ground obstacles while taxiing.
Probable cause: The pilot's loss of directional control during the rejected takeoff. Contributing to the accident were the pilot's lack of familiarity with the airport runway configuration, which led to his premature attempt to take off, and the air
Probable cause: The total loss of engine power due to fuel starvation when the cap fitting came off the inlet tee fitting on the throttle body/fuel metering unit.
Probable cause: The pilot’s selection of unsuitable terrain for landing, which resulted in a loss of directional control and subsequent nose-over.
Probable cause: The other pilot’s failure to see and avoid another airplane parked on the taxiway while taxiing in sun glare conditions.
Probable cause: The pilot's failure to maintain clearance from trees while maneuvering for landing and his decision to land on a surface with obstructions.
Probable cause: The pilot’s improper landing flare and his subsequent failure to see and avoid a tree during a go-around.
