Aircraft involved

Probable cause & findings

The pilot’s excessive braking during the landing roll, resulting in a nose over. Contributing to the accident was the pilot’s decision to continue the landing after determining the landing area was unsuitable.

Factual narrative

The pilot reported that, while landing a tailwheel-equipped airplane at a remote off airport site, he added power twice to clear areas of rough terrain just before touchdown. When the airplane eventually touched down, it bounced and continued further down the site. During the second touchdown, as the landing roll continued, the pilot realized that there was not ample room to stop the airplane before reaching the end of the site, so he applied heavy braking action. The airplane subsequently nosed over, which resulted in substantial damage to the rudder and left wing lift strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
