## 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
- Nose over, landing - flare/touchdown
  - terrain condition - soft (contributing factor)

## Analysis

THE ACFT EXPERIENCED A LOSS OF ENG PWR AT AN ALT OF APRX 400 FT AGL DURING A TAKEOFF CLIMB. THE PLT MADE A FORCED LANDING IN A MUDDY FLD NEXT TO THE RWY AND THE ACFT NOSED OVER. THE PLT THOUGHT THE SINGLE DRIVE DUAL MAGNETO HAD FAILED BUT COULD NOT BE POSITIVE BECAUSE THE MAGNETO, WIRES, AND PLUGS WERE DESTROYED BY MUD AND SALT WATER. NEW IGNITION COMPONENTS WERE INSTALLED ON THE ACFT AND THE ENG OPERATED NORMALLY DURING A TEST RUN AFTER THE ACCIDENT.
