Probable cause

The pilot’s inability to maintain airplane control during takeoff when the airplane encountered a tailwind and gusting winds which resulted in an aborted takeoff and forced landing to rough terrain.

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 reported that, during takeoff, and while in ground effect, the airplane encountered a quartering tailwind that pushed the airplane to the left and reduced the airplane’s climb performance. As the airplane passed a line of trees, at an altitude of 3-5 ft above ground level, it encountered a 90° wind gust from the left. The pilot decided to abort the takeoff when the airplane drifted further to the left and would not climb. The pilot initiated a forced landing on a rough field. The airplane’s forward fuselage was substantially damaged when it collided with the terrain and nosed down. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
