Aircraft involved

Probable cause & findings

The pilot’s failure to maintain directional control during landing with a crosswind which, resulted in a runway excursion and impact with terrain.

Factual narrative

The pilot in the tail wheel-equipped airplane reported that, while performing a touch-and-go landing with a slight crosswind from the right, the airplane drifted off the left side of the runway and into a depression in the terrain. The airplane collided with a berm which resulted in 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.
