## Sequence of events

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

- Loss of engine power, cruise - normal
  - reason for occurrence undetermined (cause)
- Forced landing, landing - flare/touchdown
  - weather condition - tailwind (contributing factor)
  - autorotation - performed, pilot in command (contributing factor)
- Fire, landing - roll

## Analysis

THE ACFT WAS DESTROYED BY FIRE AFTER A FORCED LANDING DUE TO PWR LOSS. THE PILOT STATED THAT HE WAS EN ROUTE HOME AFTER AN AERIAL APPLICATION MISSION WHEN THE ENGINE LOST POWER. HE MADE AN AUTO-ROTATION DOWNWIND AND AFTER EXITING THE ACFT NOTICED AN ENGINE FIRE. THE ACFT AND 2 ACRES OF RANGE GRASS WERE DESTROYED IN THE FIRE. FAA INSPECTORS EXAMINED THE WRECKAGE BUT COULD NOT DETERMINE THE CAUSE OF THE POWER LOSS BECAUE OF THE EXTENSIVE FIRE DAMAGE.
