The pilot’s inadequate preflight inspection during which he failed to remove all water contamination in the fuel system, which resulted in a total loss of engine power on takeoff. Contributing to the accident was the condition of the fuel caps, which allowed the water to enter the fuel system.

The pilot’s failure to maintain clearance from terrain while intentionally maneuvering in a canyon at low altitude. Contributing to the accident was the pilot’s decision to enter a canyon environment at a low altitude, and the sudden change in wind conditions within the canyon.

The pilot’s loss of control during the landing flare, which resulted in a runway excursion.

The pilot’s failure to reinstall the nose landing gear linkage prior to the flight which resulted in a loss of directional control during landing.

A loss of yaw control while on final approach, which resulted in the pilot performing an off-runway landing, and a subsequent nose over. The reason for the loss of yaw control could not be determined based on the available evidence.

The pilot’s improper brake application during the landing roll, which resulted in a nose-over.

The pilot’s loss of directional control during a high-speed taxi operation and subsequent collision with terrain during the inadvertent flight.

The pilot’s failure to maintain altitude during an instrument approach, which resulted in an impact with power lines.

The pilot’s failure to properly configure the airplane’s fuel system, which resulted in a loss of engine power on the left engine due to fuel starvation.
