The flight instructor’s failure to retract the flaps during an attempted go-around and his failure to maintain the runway heading, which resulted in a collision with terrain left of the runway.

The pilot’s selection of unsuitable terrain for landing, which resulted in a nose-over.

The flight instructor’s failure to maintain airplane control during initial climb after a touch-and-go landing, which resulted in an exceedance of the airplane’s critical angle of attack and an aerodynamic stall.

The pilot’s failure to properly secure the crew hatch door before takeoff, which resulted in his distraction and his failure to maintain airplane control and airspeed.

The pilot’s failure to maintain airplane control during a simulated single-engine go-around, which resulted in a collision with terrain.

A collision with deer on the runway while landing at night and the airport’s lack of a complete perimeter fence.

The pilot’s failure to maintain directional control during the landing roll with a gusting tailwind, which resulted in a runway excursion and collision with runway lights and taxiway signage.

The student pilot’s improper rudder input and the flight instructor’s delayed remedial action during takeoff, which resulted in a loss of directional control, a runway excursion, and the landing gear collapsing.

The pilot’s failure to maintain a stabilized approach with a tailwind and his subsequent failure to maintain yaw control during an attempted go-around.
