Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel-equipped airplane reported that, during takeoff, the airplane encountered a wind gust and veered to the left. He corrected with right rudder and left aileron, and the airplane veered to the right. Subsequently, the airplane exited the runway to the right, the left main landing gear sheared off, and the airplane impacted two trees. The airplane sustained substantial damage to the fuselage, empennage, and left wing. The pilot reported there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A review of local weather at the airfield about the time of the accident showed the wind was 300° at 10 knots. The pilot was departing on runway 34.
