The NTSB's narrative final · quoted from the NTSB record
The pilot was departing from a mountain ridgeline in gusting wind conditions. He said that he started the takeoff in what he estimated was a 5- to 10-knot headwind. At liftoff, a gust of wind raised the right wing, and the left wing struck the ground, which pivoted the airplane to the left. The airplane then continued over the ridgeline, traveled downhill, nosed over, and came to rest inverted. The airplane sustained substantial damage to both wings and the fuselage. There were no reported preaccident mechanical problems with the airplane that would have precluded normal operations.
