## Probable cause

THE FATIGUE FAILURE OF THE NO. 1 EXHAUST VALVE FOR UNDETERMINED REASONS, AND 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(total) - mech failure/malf, cruise
  - engine assembly,valve,exhaust - failure,total (cause)
  - engine assembly,valve,exhaust - fatigue (cause)
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - terrain condition - none suitable (cause)
  - object - tree(s)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE AIRPLANE WAS IN CRUISE FLIGHT AT 3,000 WHEN THE ENGINE BEGAN TO RUN ROUGH AND VIBRATE. THE ENGINE THEN FAILED AND THE PILOT EXECUTED A FORCED LANDING TO ROUGH TERRAIN BELOW. THE AIRPLANE STRUCK TREES AND CAME TO REST. THE ENGINE WAS EXAMINED AND THE NO. 1 CYLINDER EXHAUST VALVE WAS FOUND FAILED AT THE VALVE STEM IN FATIGUE. THE OUTSIDE DIAMETER OF THE VALVE STEM EXHIBITED EXCESSIVE WEAR.
