NTSB Accidents

Probable cause: The student pilot’s use of an improper engine hand-propping procedure, which resulted in the airplane’s unexpected movement.

Probable cause: The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during the takeoff initial climb, which resulted in an aerodynamic stall.

Probable cause: The pilot’s failure to see and avoid a pole during an agricultural application flight.

Probable cause: The pilot’s inadvertent landing gear retraction during the landing roll.

Probable cause: The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during a maximum performance takeoff, which resulted in an aerodynamic stall. Also causal was the pilot’s failure to use the appropriate flap setting in accordance with the manufacturer’s Maximum Performance Takeoff checklist.

Probable cause: The pilot’s inadequate preflight fuel planning, which resulted in a total loss of engine power due to fuel exhaustion.

Probable cause: The pilot’s exceedance of the airplane’s critical angle of attack during a turn away from terrain, which resulted in an accelerated stall. Contributing to the accident was the pilot’s decision to delay the turn to avoid terrain.

Probable cause: The noncertificated pilot’s decision to practice hovering the helicopter in a confined space, which resulted in the tail rotor striking a tree.

Probable cause: The pilot’s failure to maintain clearance from trees during the approach to land due to the sun glare.
