## Probable cause

AN ENGINE FIRE DURING ENGINE START FOR UNDETERMINED REASONS.

## Sequence of events

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

- Fire, standing - starting engine(s)
  - engine assembly - fire (cause)
  - reason for occurrence undetermined (cause)

## Analysis

THE PLT SAID THAT WHILE ATTEMPTING TO START THE ENGINE IN PREPARATION FOR AN AERIAL APPLICATION OPERATION, THE ENGINE BACKFIRED AND CAUGHT FIRE. BEFORE THE FIRE COULD BE EXTINGUISHED THE AIRCRAFT WAS DESTROYED BY FLAMES. THE LOCAL FIRE DEPT WAS CALLED AND RESPONDED. AS THE FIRE WAS ENGULFING THE FUEL TANK, THE ACFT WAS PULLED AWAY FROM OTHER EQUIPMENT AND HANGAR TO PREVENT ADDITIONAL DAMAGE.
