NTSB

Probable Cause: An aerodynamic stall from which the pilots did not recover while maneuvering in the airport traffic pattern.

Probable Cause: The pilot’s inadequate landing surface evaluation and failure to stop the airplane on the frozen lake, which resulted the airplane continuing into a crack in the ice.

Probable Cause: A landing gear collapse due to a hydraulic fluid leak in the landing gear system.

Probable Cause: The pilot’s exceedance of the airplane’s critical angle of attack while on final approach to land, which resulted in an aerodynamic stall, a loss of airplane control, and impact with terrain.

Probable Cause: The pilot’s failure to maintain adequate airspeed during the approach, which resulted in a hard landing.

Probable Cause: Loss of engine power due to fuel starvation that was the result of a leaking fuel drain.

Probable Cause: The pilot’s failure to attain the proper touchdown point during landing, which resulted in a runway excursion and collision with terrain and a vehicle.

Probable Cause: The collision with deer during the landing rollout.
