Primary finding
Probable cause
The pilot’s failure to maintain directional control in a gusting quartering tailwind that resulted in a loss of control and impact with trees.
Investigator assessment
Analysis narrative
The pilot reported that he attempted a takeoff with an estimated 10-12 knot left quartering tailwind. During the takeoff ground roll, the airplane veered left, departed the side of the runway, and collided with trees. The airplane sustained substantial damage to the left and right wings. The pilot reported no mechanical failures or malfunctions with the airplane that would have precluded normal operation. A review of aviation weather data found the potential for the wind to gust over 20 knots at the time of the accident.
