## Probable cause

The loss of engine power for an undetermined reason.  A contributing factor was the lack of suitable terrain for the forced landing.

## 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, emergency descent/landing
- On ground/water encounter with terrain/water, emergency landing
  - terrain condition - none suitable (contributing factor)
  - terrain condition - rough/uneven

## Analysis

The pilot reported that about 7 to 10 minutes into the flight, the engine lost power.  He restarted the engine; however, it lost power again after 30 seconds.  He selected a field and executed a forced landing.  The field was rough, and during the landing roll, the nose landing gear dug into the ground, and the airplane nosed over.  The airplane's fuselage sustained structural damage.  The reason for the loss of engine power was not determined.
