The pilot reported that during landing with a right crosswind, the airplane drifted left of runway centerline. The pilot applied right bank and left rudder control input, but the airplane continued to drift left. The pilot then increased engine power for a go-around, but the left wing dropped, and the left bank increased. The pilot continued to attempt recovery, but the airplane was too low. The airplane subsequently collided with the terrain next to the runway. The left wing and rudder sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings
