The pilot’s improper brake application during the landing roll, which resulted in a nose-over. Contributing to the accident was the pilot’s lack of recent experience using heel brakes.

The pilot’s failure to accurately assess the available runway for the takeoff, which resulted in impact with a gravel berm.

The student pilot’s failure to maintain directional control during takeoff, which resulted in a runway excursion and impact with a runway marker.

The pilot’s failure to maintain helicopter control while it was being reloaded with the rotors turning in gusting wind conditions, which resulted in a rotor strike with ground equipment.

The pilot’s failure to maintain directional control and runway heading during landing, which resulted in a runway excursion and the nose landing gear collapsing.

The pilot’s overapplication of the brakes during landing on a grass runway, which resulted in a nose-over.

The pilot receiving instruction’s failure to maintain directional control during landing, which resulted in an attempted go-around and collision with a trench, and the flight instructor’s delayed remedial action during the landing.

The pilot’s improper decision to launch the balloon in known high wind conditions, and his failure to fully vent the balloon upon landing, which resulted in the balloon landing hard several times, tipping over, being pushed along uneven ground, and a serious passenger injury.

The pilot’s inadequate preflight fuel planning and fuel management, which resulted in a loss of engine power due to fuel exhaustion. Also causal was the pilot’s failure to follow the one-engine inoperative checklist and maintain the airplane’s minimum controllable airspeed by properly configuring the airplane, which resulted in a loss of airplane controllability.
