Probable cause: The contamination of snow and ice on the left main landing gear and brake, which prevented the wheel from rolling during touchdown and resulted in a nose-over.

Probable cause: The pilot’s inadequate preflight and inflight fuel planning, which resulted in a total loss of engine power due to fuel exhaustion and subsequent forced landing in a field. Contributing to the accident was the pilot’s delayed action in taking contr

Probable cause: A decrease in oil pressure due to the pilot’s unintentional overfilling of the engine oil sump, and the pilot’s subsequent decision to perform an off-airport precautionary landing, which resulted in impact with a tree.

Probable cause: The failure of the engine No. 2 connecting rod bearing for reasons that could not be determined due to the extensive secondary engine damage.

Probable cause: The pilot’s continued visual flight rules flight into instrument meteorological conditions, which resulted in controlled flight into terrain. Contributing to the accident were the pilot’s inadequate preflight weather planning a

Probable cause: The pilot’s failure to maintain clearance from a hangar while taxiing at night.

Probable cause: The pilot’s exceedance of the airplane’s critical angle of attack during an attempted go-around, which resulted in an aerodynamic stall.

Probable cause: The flight instructor’s exceedance of the critical angle of attack during a go-around, which resulted in an aerodynamic stall/spin. Contributing to the accident was the flight instructor’s failure to familiarize himself with the flight character

Probable cause: The pilot’s abrupt maneuver to avoid birds during short final approach, which resulted in a hard, bounced landing.
