The student pilot’s failure to maintain the runway heading during takeoff, which resulted in impact with a snowbank and a subsequent nose-over.

The pilot’s improper landing flare, which resulted in a bounced landing, and his subsequent failure to maintain directional control, which resulted in a runway excursion and impact with sign.

The pilot receiving instruction’s failure to maintain directional control during the takeoff roll, which resulted in a runway excursion and ground-loop, and the flight instructor’s failure to adequately monitor the pilot.

The student pilot’s failure to maintain directional control and his use of excessive braking while taxiing.

The pilot’s selection of unsuitable terrain for landing, which resulted in impact with a knoll and a subsequent ground-loop.

The student pilot’s improper landing flare, which resulted in a bounced landing, and the flight instructor’s delayed remedial action and the student’s failure to relinquish control, which resulted in a runway overrun and impact with a fence.

The pilot’s failure to set the friction lock on the throttle before hand propping the engine, which allowed the airplane to move forward and hit a credit card machine. Contributing to the accident was the malfunction of the parking brake for reasons that could not be determined.

The total loss of engine power due to fuel exhaustion, which resulted from the pilot’s inadequate preflight fuel inspection.

The student pilot’s inadvertent movement of the fuel shutoff switch to the “off” position while attempting to take a picture of himself, which resulted in a total loss of engine power due to fuel starvation and a subsequent ditching in open water.
