## Probable cause

The pilot's failure to maintain directional control and his excessive use of brakes during the landing which resulted in a nose-over.  The downhill slope was a contributing factor.

## 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
  - directional control - not maintained, pilot in command (cause)
- Nose over, landing - roll
  - terrain condition - downhill (contributing factor)
  - brakes(normal) - excessive, pilot in command (cause)

## Analysis

The airplane was damaged when it nosed over during an off-airport landing on a farm field.  The pilot reported that during the landing roll he lost directional control of the airplane and it traveled down a slope to the side of the landing area.  He said that when he applied the brakes the airplane nosed over.
