Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, while on final approach to land, the descent was too fast, and he applied power to slow the descent rate. The main landing gear touched down on the runway surface and the airplane bounced with a nose high attitude. While pitching the airplane forward to correct, he misjudged the height above the runway, the propeller impacted the runway surface and the airplane nosed over. The airplane sustained substantial damage to both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
