NTSB narrative
THE COMMERCIAL AG PILOT WAS ABOUT 5 MINUTES INTO HIS FLIGHT WHEN THE ENGINE LOST POWER AND QUIT. DURING THE AUTOROTATION, THE HELICOPTER LANDED HARD, AND THE TAIL BOOM CONTACTED THE GROUND. THE PILOT REPORTED THAT HE BEGAN THE FLIGHT WITH ABOUT 10 GALLONS OF FUEL, WHICH HE MEASURED WITH A DIP STICK THAT HE CARRIED IN THE COCKPIT. HE STATED THAT THE EXPECTED FUEL CONSUMPTION WAS ABOUT 15 GALLONS PER HOUR. THE FUEL SYSTEM SURVIVED THE ACCIDENT INTACT. FAA INSPECTORS FOUND NO EVIDENCE OF FUEL IN THE TANK OR IN THE LINES. THE FUEL GAUGE INDICATED EMPTY.
Probable cause
THE PILOT'S INADEQUATE PREFLIGHT OF THE AIRCRAFT, RESULTING IN FUEL EXHAUSTION, AND HIS IMPROPER FLARE OF THE HELICOPTER DURING THE AUTOROTATION, RESULTING IN A HARD LANDING.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
