The pilot’s failure to maintain a proper glidepath during a night landing, which resulted in impact with a tree.

The pilot receiving instruction’s failure to extend the landing gear and the flight instructor’s failure to verify that the landing gear was extended due to distraction, which resulted in a gear-up landing.

The failure of the left main landing gear attachment point during the landing roll for reasons that could not be determined because the attachment was not examined, which resulted in a loss of directional control, collision with a drainage culvert, and a subsequent nose-over.

The pilot’s failure to maintain the proper airspeed and his exceedance of the airplane’s critical angle of attack during a low-altitude climbing turn, which resulted in an aerodynamic stall.

The pilot’s failure to see and avoid a windmill tower while maneuvering at low altitude.

The pilot’s geographic disorientation and his exceedance of the airplane’s critical angle of attack while maneuvering to avoid mountainous terrain, resulting in an aerodynamic stall.

The pilot’s loss of control for undetermined reasons.

The pilot’s excessive brake application during landing on a short runway due to his lack of familiarity with the toe brakes, which resulted in a nose-over.

The pilot’s failure to properly lean the fuel mixture in flight, which resulted in fuel exhaustion, a subsequent total loss of engine power, and a forced landing with the landing gear retracted.
