## Sequence of events

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

  - engine assembly,push rod - failure,total (cause)
- Forced landing, descent - emergency
- Nose over, landing - roll
  - terrain condition - none suitable (contributing factor)

## Analysis

THE PILOT STATED HE MADE A SUCCESSFUL FORCED LANDING, DUE TO LOSS OF POWER, AND THEN HAD TO FLIP THE AIRCRAFT TO PREVENT COLLIDING WITH A LATERAL (ABOVE GROUND IRRIGATION SYSTEM) WITH A WATER DEPTH OF ABOUT FOUR FEET. SUBSEQUENT ENGINE EXAMINATION REVEALED THAT AN ENGINE VALVE PUSH ROD HAD BROKEN AND RESULTED IN THE LOSS OF POWER.
