Probable Cause: The pilot’s failure to secure the seat’s position in the seat rail, which resulted in a loss of directional control and nose over.

Probable Cause: The pilot’s inadequate compensation for prevailing wind conditions during the landing approach, which resulted in the airplane contacting the ground short of the runway.

Probable Cause: A failure of the No. 2 connecting rod, which resulted in a total loss of engine power.

Probable Cause: The pilot’s improper fuel management, which resulted in fuel starvation and a total loss of engine power.

Probable Cause: The flight instructor’s exceedance of the airplane’s critical angle of attack during the initial climb, which resulted in an aerodynamic stall and subsequent rapid descent into terrain.

Probable Cause: The pilot’s inadequate fuel management which resulted in a total loss of engine power due to fuel exhaustion.

Probable Cause: The student pilot’s failure to maintain airplane control after takeoff that resulted in an impact with terrain.

Probable Cause: The pilot’s failure to maintain proper airspeed on approach, which resulted in an extended touchdown, loss of control, and runway excursion.
