Narrative:The helicopter landed hard following a loss of rotor rpm during the landing attempt. The pilot stated that during the landing attempt, approximately 20 feet above ground level, the low rotor RPM horn sounded along with the corresponding warning light. The pilot reported the helicopter "settled rapidly" as he lowered the collective and increased the throttle. The pilot stated that the helicopter was too low for a successful recovery and impacted left skid first. The pilot reported "It may have been possible that I delayed throttle governor by initially holding throttle/collective control too tightly." The pilot also stated that the accident could have been prevented by "closer observation of [the] main rotor RPM."
Probable Cause: The pilot's failure to maintain proper rotor RPM during the hover landing and his inadequate remedial action, which resulted in the hard landing.
