The pilot’s failure to extend the landing gear before landing. Contributing to the accident were the pilot’s inability to see the landing gear position light because his iPad was blocking his view of it and his feeling of being rushed during the approach and landing.

The student pilot’s complacency, which led to his improper crosswind correction and subsequent failure to maintain directional control during the landing roll, which resulted in a runway excursion and ground collision.

The pilot’s distraction during the engine warm-up, which resulted in the airplane’s collision with a hangar. Contributing to the accident was the pilot’s failure to set the brakes.

The pilot’s failure to maintain to directional control during takeoff from a snow-covered runway with a right, quartering tailwind, which resulted in a runway excursion and impact with a snowbank.

The pilot’s failure to use carburetor heat while operating the airplane in weather conditions and at engine power settings conducive to the formation of carburetor ice, which resulted in a loss of engine power due to carburetor icing and the subsequent forced landing.

The pilot’s failure to maintain lateral control during the landing flare, which resulted in the left wing striking a tree.

The student pilot’s improper decision to release the seat latch to adjust the seat position during taxi, which resulted in his inability to reach the rudder or brake pedals and a subsequent loss of directional control and impact with a ditch and fence.

The pilot’s failure to maintain pitch control while conducting a touch-and-go landing on an unimproved, snow-covered airstrip, which resulted in a nose-over.

The noncertificated pilot’s exceedance of the aircraft’s critical angle of attack, which resulted in an aerodynamic stall.
