The pilot’s failure to maintain airplane control during an attempted go-around.

The pilot’s spatial disorientation and loss of airplane control following takeoff in night instrument meteorological conditions.

The pilot’s improper crosswind correction during taxi operations in gusting crosswind conditions.

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.
