NTSB Factual Report

The pilot reported that on takeoff roll just after the tail came up he encountered a right quartering tail wind gust, which forced the airplane off of the left side of the runway. The pilot subsequently corrected back to the right but crossed the runway, a gully and a taxiway. He then intentionally applied right brake and ground looped the airplane to avoid colliding with a hangar, which resulted in the collapse of both main landing gear. A post crash fire erupted shortly thereafter, which consumed the airplane.

NTSB Probable Cause

The pilot's loss of directional control during takeoff roll upon encountering a wind gust.
