NTSB Factual Report

The pilot reported that during a full stop landing on a grass strip, rolling out at 20 mph, the airplane started veering left and he applied right rudder and right brake. The airplane abruptly nosed over and came to rest inverted substantially damaging the aft fuselage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control during the landing roll, which resulted in the airplane nosing over.
