Aircraft: Cessna 172
Aircraft Damage: Substantial
Defining Event: Abnormal runway contact
Injuries: 1 None

The pilot reported that, while in the pattern for landing, he turned a short base leg, followed by a short final approach leg. A “rapid roundout” was initiated at touchdown which resulted in the airplane bouncing. During the last bounce, the nose gear sheared off and the airplane subsequently nosed over coming to rest inverted. The right wing and wing lift strut were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s improper landing flare which resulted in a bounced hard landing and subsequent nose over.
