- 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
DRG AN EMERGENCY MEDICAL SVC (EMS/MEDEVAC) FLT, THE PLT ENCTRD STRONGER HEADWINDS THAN EXPECTED. AFTER DELIVERING A PATIENT, HE ESTIMATED 12 MIN OF FUEL WAS REMAINING. SINCE THE FLT TO HIS HOME BASE WOULD TAKE ABOUT 6 MIN, HE ELECTED TO RETURN WITHOUT REFUELING. WHILE ARRIVING ABEAM OF HIS DESTN, A FUEL BOOST PUMP LIGHT ILLUMINATED. THE PLT SAID HE EXPEDITED HIS APCH, BUT AT ABOUT 50' AGL, A 2ND BOOST PUMP LIGHT ILLUMINATED. THE ENG THEN LOST POWER FROM FUEL EXHAUSTION. SUBSEQUENTLY, THE HELICOPTER WAS DAMAGED DRG AN EMERGENCY AUTOROTATION (AT NIGHT).
Probable cause
IMPROPER PLANNING/DECISION BY THE PILOT, WHICH RESULTED IN FUEL EXHAUSTION DUE TO AN INADEQUATE SUPPLY OF FUEL. DARKNESS WAS A RELATED FACTOR.

- 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.
