## Probable cause

THE FAILURE OF THE ENGINE FOR UNDETERMINED REASONS.  FACTORS WERE THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING AND THE ROUGH TERRAIN THAT WAS ENCOUNTERED.

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

## Analysis

THE PILOT STATED THAT SHORTLY AFTER CONFIGURING THE AIRPLANE FOR LOW LEVEL CRUISE FLIGHT, HE BEGAN TO LOSE ENGINE POWER AND WHEN HE ADVANCED THE THROTTLE AND PROPELLER CONTROLS THE ENGINE QUIT COMPLETELY. THE PILOT ELECTED TO LAND ON A HIGHWAY RIGHT OF WAY. THERE WAS NO OTHER SUITABLE TERRAIN. POST ACCIDENT INVESTIGATION DID NOT REVEAL THE CAUSE FOR THE ENGINE FAILURE.
