Probable cause

Analysis

The pilot stated that as the airplane settled on the runway, it passed several hangars and a hill, and the tail was pushed by a crosswind. The pilot tried to correct the movement but was unsuccessful. The airplane departed the runway at 35-40 mph, pivoted up on the nose, twisted to the right, and settled back down on its landing gear. A postaccident examination of the airplane revealed that it sustained substantial damage to the left wing. The pilot reported that the airplane and engine experienced no mechanical failures or malfunctions that would have precluded normal operation.
