The failure of maintenance personnel to properly connect the throttle cable, which led to the pilot’s inability to control engine power during the initial climb. Contributing to the accident was the pilot’s misjudgment of the headwind during the forced landing, which resulted in the airplane’s touchdown short of the runway and its impact with airport structures.

The student pilot’s improper fuel management, which resulted in a total loss of engine power due to fuel starvation.

The pilots’ exceedance of the airplane’s critical angle of attack while practicing maneuvers during an instructional flight, which resulted in an aerodynamic stall and a loss of airplane control.

The pilot’s decision to continue the flight with abnormal engine indications and the subsequent failure of the No. 5 cylinder connecting rod for unknown reasons.

The pilot’s failure to maintain a proper glidepath while on the final approach segment of the traffic pattern in dark night conditions.

The pilot’s inadequate preflight and in-flight weather planning and his improper decision to continue visual flight rules flight into an area of limited visibility in moderate precipitation, which resulted in a loss of airplane control due to spatial disorientation.

The pilot’s loss of airplane control in night instrument meteorological conditions during the procedure turn of an instrument approach due to spatial disorientation, which resulted in a collision with terrain.
