## Probable cause

CONTAMINATION OF THE FUEL SYSTEM BY PARTICULATE MATTER OF AN UNKNOWN ORIGIN.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise
  - fluid,fuel - contamination (cause)
- Forced landing, landing - flare/touchdown
- Hard landing, landing - flare/touchdown

## Analysis

THE PILOT REPORTED THAT THE ENGINE MISSED SEVERAL TIMES & THEN QUIT COMPLETELY. HE MADE AN AUTOROTATION TO A FIELD; THE HELICOPTER LANDED HARD & ROLLED OVER. INSPECTION DISCLOSED EXTENSIVE CONTAMINATION OF THE FUEL SYSTEM WITH SAND-LIKE PARTICULATE MATTER. ONCE THE SYSTEM WAS CLEANED, THE ENGINE STARTED AND RAN NORMALLY. THE SOURCE OF THE PARTICULATE MATTER WAS NOT DETERMINED.
