Probable cause: The pilot’s selection of unsuitable terrain for landing, which resulted in a nose-over.

Probable cause: The pilot’s failure to extend the landing gear before landing. Contributing to the accident were pilot fatigue and his failure to use the before landing checklist.

Probable cause: The pilot’s inability to gain altitude normally in order to avoid a flock of ducks flying overhead during takeoff, which resulted in the airplane striking a fence.

Probable cause: The student pilot’s failure to maintain directional control during landing.

Probable cause: The pilot’s failure to see the taxiway when returning to the ramp from the snow-covered runway, which resulted in the airplane rolling down an embankment.

Probable cause: The pilot’s improper fuel planning, which resulted in a total loss of engine power due to fuel exhaustion and a subsequent off-airport landing and nose-over.

Probable cause: The pilot’s failure to maintain directional control during landing due to being distracted by another airplane and her delayed initiation of a go-around, during which the right wing struck a parked helicopter.

Probable cause: The pilot’s failure to maintain directional control while taxiing in gusting tailwind conditions.

Probable cause: The pilot’s selection of unsuitable terrain for takeoff, which resulted in a loss of directional control.
