NTSB Factual Report

The pilot reported that during the landing with a gusting crosswind and a wind shift to a quartering tailwind, the airplane's right wing lifted up after he had lowered the tail to the runway. He  applied corrective control inputs, however, the airplane yawed sideways causing the left landing gear to collapse and substantial damage to the left wing.  The pilot reported no preimpact mechanical malfunctions or failures that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control during landing with gusting wind and a quartering tailwind.
