The pilot reported that, during landing with a crosswind, before touchdown, a wind gust pushed the airplane left. The airplane touched down, the pilot attempted to correct, but the airplane exited the runway to the left. The left wing struck the ground, and the empennage separated. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The pilot reported that the wind was variable from 080° to 110° and gusting between 12 and 18 knots. The pilot landed the airplane on runway 06.
