## Probable cause

The pilot's excessive braking during the landing roll, which resulted in a loss of control and a nose over.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - terrain condition - loose gravel/sandy
  - brakes(normal) - excessive, pilot in command (cause)
- Nose over, landing - roll

## Analysis

The student pilot reported that he was landing a tailwheel-equipped airplane on a gravel bar during a Title 14, CFR Part 91 personal flight.  He stated that during the landing roll he applied the brakes too hard, and the airplane nosed over, damaging both wing lift struts and a wing spar.  He also indicated that there were no mechanical anomalies with the airplane prior to the accident.
