The pilot’s failure to lower the landing gear before landing. Contributing to the accident was the examiner’s failure to check that the landing gear was extended.

The pilot’s loss of directional control during the landing roll on the slush-covered runway.

The flight instructor’s inadequate communication with the pilot under review about his intention to simulate a single-engine failure and his subsequent exceedance of the airplane’s critical angle of attack when the pilot did not respond as expected, which resulted in an aerodynamic stall at low altitude.

The student pilot’s failure to maintain directional control while landing on the snow/slush-covered portion of the runway and the flight instructor’s improper decision to allow the student to make his first solo flight from a snow/slush-covered runway.

The pilot’s failure to maintain airplane control during a go-around. Contributing to the accident was the pilot’s decision to take off after perceiving a rudder issue during taxi operations.

The student pilot’s failure to maintain a proper airspeed and descent rate while conducting a low pass over a snow-covered runway after encountering a downdraft and the flight instructor’s delayed action, which resulted in the wheels contacting the snow and the airplane nosing over.

The rear seat pilot and the student pilot’s failure to see and avoid trees during initial climb following an aborted landing.

The inadvertent engine start of the unoccupied airplane, which resulted in it moving forward and impacting a hangar and an electrical box.

The pilot’s failure to complete a before landing checklist, which resulted in his delayed extension of the landing gear, and his subsequent exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.
