Probable cause
A total loss of engine power due to fuel exhaustion as a result of the pilot's inadequate in-flight planning and his decision to continue flight with a known low fuel level state.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that at 70 miles from his destination he determined that he would be landing closer to minimum fuel than he had planned. He continued to the destination and passed over one airport because it did not have any services. At 35 miles from the destination, the low fuel caution-warning for fuel tank 2 illuminated, followed by a low fuel caution-warning for fuel tank 1. The pilot thought that he would still land with some reserve and continued to fly to his destination airport. Approximately 1 mile from the destination airport the helicopter experienced a dual engine flame-out. The pilot autorotated to a sports field where the helicopter landed hard, sustaining damage to the main rotor blades, tail rotor, tail boom, and horizontal stabilizer. The pilot stated that the helicopter and engines had no mechanical failures or malfunctions during the flight.
