The pilot’s overapplication of the brakes during landing and the subsequent loss of directional control and nose-over.

The pilot’s misjudgment of a ground spray rig’s position and his incorrect belief that a runway incursion might occur, which resulted in the pilot attempting and then aborting a go-around, which resulted in a runway excursion and collision with a fence.

A gradual loss of engine power during takeoff due to the pressure regulator not keeping continuous fuel pressure which led to a precautionary off airport landing and collision with terrain.

The pilot’s inadequate preflight planning and attempted takeoff with obstacles in the direction of departure, and his failure to maintain control of the airplane during the rejected takeoff.

The pilot’s failure to maintain airplane control during landing with a gusting quartering tailwind.

The pilot’s failure to extend the landing gear before landing due to distraction by the condition of the runway and his failure to use the Before Landing checklist.

The pilot’s failure to attain sufficient altitude during a go-around, which resulted in impact with hilly terrain.

The pilot’s failure to maintain clearance from a tree while maneuvering at low altitude.

The pilot’s inadequate preflight inspection of the fuel level, which resulted in a total loss of engine power due to fuel exhaustion.
