Probable cause

the pilot's failure to compensate for prevailing wind conditions and to maintain directional control. Factors were the gusting and quartering tailwind conditions.

Analysis

The pilot said that as power was applied during his takeoff roll on runway 17, the left wing dropped due to engine torque. A right wind gust caused the airplane to swerve to the left and depart the runway. The nose wheel retract link broke when the nose wheel rolled into the dirt and the landing gear folded back, causing the airplane to nose over. The wind was from 320 degrees at 8 knots, with gusts to 16.
