Probable cause: The pilot’s decision to take off in gusting wind conditions, which resulted in a loss of directional control.

Probable cause: The pilot’s failure to maintain directional control during a rejected takeoff in gusting quarting tailwind conditions.

Probable cause: The pilot’s improper landing flare, which resulted in a hard landing.

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

Probable cause: The pilot’s loss of directional control and long landing in gusting wind conditions due to his shoe getting stuck on the brakes. 

Probable cause: The pilot’s failure to secure the canopy before flight, which resulted in the airplane hitting a fence during the approach. Contributing to the accident was the pilot’s failure to follow the Before Takeoff checklist and In-flight Canopy Opening checklist emergency procedure.
