Aircraft involved

Probable cause & findings

The pilot's improper decision to land on unsuitable terrain, which resulted in a nose-over.

Factual narrative

The pilot of the tailwheel-equipped airplane reported that, upon completion of the landing roll on a grass area adjacent to an asphalt runway, the main landing gear dug into an area of soft grass and the airplane nosed over. The airplane sustained substantial damage to the fuselage, vertical stabilizer and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
