What happened
The pilot was conducting a local pleasure flight with the specific intent of observing and filming the changing colors of autumn leaves. During this scenic transit, the low fuel warning light illuminated on the instrument panel. Approximately two minutes after the warning activated, the aircraft engine lost power completely.
In response to the sudden loss of propulsion, the pilot initiated an emergency landing procedure in a nearby field. However, the helicopter experienced a critical loss of main rotor revolutions per minute (RPM) before touchdown could be safely achieved. The aircraft impacted the ground with significant force and subsequently rolled over.
The investigation
Post-accident examination revealed that the helicopter sustained substantial damage as a direct result of the hard landing and rollover. The sequence of events indicates that the mechanical failure was preceded by the fuel system warning, suggesting an operational depletion of resources rather than a sudden mechanical malfunction.
Findings
The primary factors leading to this incident were the loss of engine power due to fuel exhaustion and the subsequent inability to maintain rotor RPM during the emergency descent. The pilot's decision to continue the flight after the low fuel warning illuminated contributed to the critical state of the aircraft prior to touchdown.
Safety message
Pilots must recognize that a low fuel warning light indicates an immediate need to land, not merely a suggestion to monitor levels. Continuing flight operations after such a warning significantly increases the risk of in-flight power loss and subsequent loss of control during emergency landing attempts.
