## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, cruise - normal
  - engine assembly,valve,intake - separation (cause)
  - engine assembly,cylinder - low compression
- Forced landing, descent
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

THE PILOT STATED THAT WHILE CRUISING AT 11,000 FT THE ENGINE STARTED MISSING AND LOSING POWER. AFTER REPEATED ATTEMPTS TO RESTORE POWER THE PILOT LANDED IN A FIELD. DURING ROLL OUT THE NOSE WHEEL BECAME LODGED IN SOFT SAND AND THE AIRCRAFT TURNED OVER. ENGINE EXAMINATION REVEALED NO COMPRESSION IN THE NUMBER 1 CYLINDER DUE TO VALVE SEPARATION. THE VALVE STEM WAS "SEIZED" IN THE VALVE GUIDE.
