- Total loss of engine power (non-mechanical)
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Fuel exhaustion
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
THE PILOT CALCULATED HE HAD OVER 2 HOURS OF FUEL FOR THE FINAL LEG OF THE FLIGHT. HE FOUND HE WAS OFF COURSE TO THE WEST, SO HE LANDED THE HELICOPTER TO FIND HIS POSITION, WITHOUT SHUTTING DOWN THE ENGINE. HE TOOK OFF HEADING EAST AND HAD TO LAND AGAIN TO GET HIS POSITION, THIS TIME SHUTTING THE ENGINE OFF. HE WAS 5 MILES SOUTH OF HIS INTENDED LANDING AIRPORT. THE PILOT SAID AT THIS POINT HE HAD ABOUT 4 GALLONS OF FUEL. WHILE ON APPROACH TO THE AIRPORT THE ENGINE FAILED AND HE MADE A FORCED LANDING IN A CEMETERY. HE LANDED SHORT OF HIS INTENDED LANDING AREA AND IMPACTED WITH A HEAD STONE.
Probable cause
THE PILOT'S FAILURE TO REFUEL RESULTING IN A POWER FAILURE DUE TO FUEL EXHAUSTION, AND SUBSEQUENT FORCED LANDING IN UNSUITABLE TERRAIN.

- 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.
