NTSB narrative
The certificated commercial pilot was returning to the airport. He stated that he knew he was low on fuel, but thought he had enough fuel to return since the low fuel light had not illuminated. He said that while on approach to land at the airport, about 400 feet above the runway, all engine power was lost. He entered an autorotation, flared the helicopter about five feet above the runway, and touched down on the runway edge. The pilot said that as the helicopter touched down, the left skid assembly collapsed, and the helicopter rolled over to the left. A pilot-rated witness observed the helicopter enter an autorotation to the runway, and while still about 50 feet above the runway, the accident pilot flared, and the rotor rpm decayed rapidly. He said that the helicopter landed hard on the left skid, which collapsed the left skid, and the helicopter rolled over on its left side. An FAA inspector that examined the helicopter stated that the fuel quantity indicator read 'zero,' and that the fuel low indicator light was not illuminated. He said that when the 'press to test' feature on the warning light was used, the light then illuminated. He added that an inspection of the helicopter's fuel cell revealed about one pint of fuel remaining. The McDonnell Douglas (Hughes) 500D pilot operating handbook, Emergency and Malfunctions Procedures section, states: 'CAUTION: Never use the FUEL LEVEL LOW light as a working indication of fuel quantity.'
Probable cause
The pilot's failure to refuel the helicopter prior to fuel exhaustion. Factors associated with the accident were an inoperative low fuel warning system, and the pilot's improper autorotation.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1999-07-31.
