Probable cause: A total loss of engine power during takeoff for reasons that could not be determined based on available information.

Probable cause: The pilot’s inadequate preflight planning, his decision to take off knowing the airplane was over its gross takeoff weight, and his failure to abort the takeoff after he realized that the airplane was not accelerating as expected, which resulted in a runway excursion.

Probable cause: The overstress failure of the landing gear connecting rod and the improper installation of the arresting cables, which allowed the landing gear door to depart in flight and impact the airplane.

Probable cause: A collision with deer on the runway during the takeoff roll.

Probable cause: The non-certificated pilot’s loss of airplane control while maneuvering at a low altitude.

Probable cause: The pilot’s improper compensation for changing wind during the landing flare, which resulted in an off-centered landing and a subsequent loss of directional control.

Probable cause: A total loss of engine power due to fuel vapor lock. Contributing to the loss of engine power were the corrosion of the spark plugs and the spacing of the electrode gaps.

Probable cause: The pilot’s failure to maintain clearance from trees while maneuvering at a low altitude.

Probable cause: The pilot’s failure to verify the usable fuel in the fuel tanks, which resulted in an inaccurate fuel totalizer setting during preflight, fuel exhaustion, and a total loss of engine power.
