Written off (damaged beyond repair) June 6, 1991 when crashed due to engine failure, caused by fuel exhaustion at
Lihue Airport, Kauaʻi, Kauai County, Hawaii. Of the four persons on board (pilot and three passengers), the pilot was slightly injured, but the three passengers sustained serious injuries

During a sightseeing flight a fuel pump caution light came on. The pilot noted that the fuel level was low but decided that sufficient fuel remained to land safely back at Lihue. Subsequently, during final approach, while descending through about 50 feet agl at about 40 knots airspeed, the helicopter's engine stopped. The pilot carried out an auto-rotation landing but the helicopter touched down hard, collapsing its skids and then impacted the airport perimeter fence. All available fuel was exhausted.

The helicopter was refuelled prior to the third departure, of a total of five flights. Following a lunch break, the pilot departed on the accident flight. Company manifest sheets for each flight list a standard fuel load of 40 or 65 gallons. In this accident, the manifest sheets did not accurately reflect the actual quantity of fuel on board for each flight. The pilot did not visually verify the actual fuel amount before the accident flight.

The NTSB determined the probable cause to be: Fuel exhaustion. A factor related to the accident was the failure of the pilot to ensure that sufficient fuel was available for the flight. Registration N2120X cancelled by the FAA on December 12, 1991 as "destroyed"
