## Probable cause

THE COMPLETE LOSS OF ENGINE POWER FOR UNDETERMINED REASON.

## Sequence of events

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

- Loss of engine power, maneuvering - turn to reverse direction
  - reason for occurrence undetermined (cause)
- In flight collision with terrain/water, descent - emergency
  - terrain condition - crop
- Fire/explosion, other

## Analysis

THE PILOT COMPLETED THE FIRST APPLICATION OF DEFOLIANT ON A CULTIVATED FIELD AND AS HE BEGAN HIS TURN FOR ANOTHER PASS, THE ENGINE STARTED TO RUN ROUGH. AS HE COMPLETED HIS TURN, AND LEVELED THE AIRPLANE, HE EXPERIENCED A COMPLETE LOSS OF ENGINE POWER. THE AIRPLANE IMPACTED IN A PLOWED FIELD IN A NOSE DOWN ATTITUDE, SKIDDED 15 FEET, CAUGHT ON FIRE AND EXPLODED. THE POWERPLANT AND ENGINE COMPONENTS WERE TOO BADLY DAMAGED BY POST-IMPACT FIRE TO DETERMINE THE CAUSE OF THE POWER LOSS.
