The pilot’s poor preflight planning, during which he failed to verify the proper procedure to activate the runway lights; his inability to locate the airport without lighting; and the airplane’s subsequent low-fuel state as he circled looking for the airport, which necessitated a precautionary off-airport landing, during which the nose landing gear separated.

The pilot’s failure to maintain airplane control during landing, which resulted in the right tire contacting the runway first followed by the left wing.

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.
