Analysis

According to the pilot, the airplane bounced during the initial touchdown and then it veered slightly to the right of the gravel-covered runway. To correct for the veer, the pilot applied left rudder and braking, but the airplane subsequently nosed over, sustaining substantial damage to the fuselage, empennage, and left wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. In addition, the pilot noted that he inadvertently applied aggressive braking action, which resulted in the nose over.
