The pilot’s delayed decision to go around, which resulted in a collision with trees and terrain.

The student pilot’s maneuver to the left to avoid striking birds during takeoff and his subsequent loss of directional control after aborting the takeoff and landing on soft, muddy grass adjacent to the runway during, which resulted in a nose-over.

The pilot’s attempt to land on water in an airplane that was not equipped with floats.

The pilot’s failure to properly secure the airplane before hand propping it, which resulted in the unmanned airplane moving and colliding with a fence.

The noninstrument-rated pilot’s decision to continue visual flight rules flight into an area of instrument meteorological conditions, which resulted in a loss of control due to spatial disorientation. Contributing was the pilot not obtaining a weather briefing prior to the flight.

The pilot’s failure to properly tighten his seat belt, which allowed him to slide forward in his seat and resulted in his inadvertent application of excessive brake application during the landing roll and a subsequent noseover.

The pilot’s improper fuel planning, which resulted in fuel exhaustion and a total loss of engine power, and his improper landing flare during a forced autorotation, which resulted in a hard landing. Contributing to the accident were the inoperative fuel gauge, which was not accurately calibrated, and the pilot’s reliance on the gauge.

The airplane’s collision with deer during the landing and the airport’s failure to provide an adequate barrier to prevent wildlife from entering the runway environment despite previous deer strikes.

The pilot’s failure to maintain clearance from power lines during low-altitude maneuvering.
