Probable cause: The pilot’s failure to maintain directional control during the landing roll on a wet surface.

Probable cause: The pilot receiving instruction’s failure to see and avoid an airplane holding short of the runway on the taxiway and the flight instructor’s lack of situational awareness.

Probable cause: The passenger’s gun becoming lodged in the flight controls during takeoff and his failure to remove it, which resulted in impact with terrain.

Probable cause: The pilot’s failure to maintain clearance from an elk while maneuvering at a low altitude.

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.
