## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
  - load jettison - performed, pilot in command
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)

## Analysis

AFTER A NORMAL TAKEOFF AND CLIMB TO 200 FEET AGL THE PILOT REDUCED POWER AND THE ENGINE QUIT. A FORCED LANDING WAS MADE INTO A DRY BUT SOFT PLOWED FIELD. THE AIRCRAFT ROLLED 300 FEET AND THEN NOSED OVER INTO AN INVERTED ATTITUDE AND STOPPED. THE ENGINE WAS SUBSEQUENTLY REMOVED AND PLACED ON A TEST STAND WHERE AN ENGINE RUN WAS CONDUCTED. NO DISCREPANCIES WERE NOTED. THE REASON FOR ITS PREVIOUS STOPPAGE WAS NOT DETERMINED.
