## Probable cause

A LOSS OF ENGINE POWER FOR UNDETERMINED REASONS. THE DIRT BANK CONTACTED DURING THE LANDING IS CONSIDERED TO BE CONTRIBUTING FACTOR.

## Sequence of events

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

- Loss of engine power, cruise
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - dirt bank/rising embankment (contributing factor)

## Analysis

THE PLT STATED THAT THE ENG STARTED RUNNING ROUGH DURING THE FLT AND HE SELECTED A PLACE TO LAND. DURING THE LANDING ROLL IN A FIELD, THE AIRPLANE HIT A DIRT MOUND AND THE AIRPLANE WENT UP ON ITS NOSE. EXCEPT FOR A SMALL AMOUNT OF DEBRIS AND WATER IN THE FUEL SYSTEM, NOTHING COULD BE FOUND THAT WOULD HAVE CAUSED A POWER LOSS.
