Aircraft involved
Probable cause & findings
The pilot’s rapid reduction of collective following an in-flight loss of control while lifting from a dolly resulting in a hard landing. Contributing to the loss of control was the pilot’s likely inadequate left anti-torque control pedal input during initial liftoff.
Factual narrative
The pilot stated there were no discrepancies of the anti-torque pedals noted during his check of them as part of the startup checklist or after starting the engines. After lifting off from a dolly while operating about 150 pounds below gross weight, he reported “suddenly and without notice” a “pop” in the pedals. The helicopter began yawing to the right, which he attempted to correct with left anti-torque pedal input but did not recall if the pedal moved. The helicopter yawed about 180° clockwise and impacted a parked golf cart which stopped the yaw. He then lowered the collective which resulted in the helicopter landing partially on the dolly. He then raised collective and lifted from the dolly but after getting airborne the helicopter yawed left which he attempted to correct with right anti-torque pedal input. After clearing the dolly, he lowered collective and the helicopter impacted hard on the ramp resulting in substantial damage to the tailboom. The pilot indicated on the NTSB Pilot/Operator Aircraft Accident/Incident report there was no mechanical malfunction or failure. Postaccident examination of the helicopter by a Federal Aviation Administration (FAA) airworthiness inspector with the accident pilot present revealed no evidence of preimpact failure or malfunction of the anti-torque flight controls. While binding was noted in the anti-torque flight controls during postaccident examination, that was attributed to be from impingement of a displaced skid cross tube into a bellcrank of anti-torque control system. The lack of any malfunction of the anti-torque flight controls was further supported by the pilot and witness accounts, as well as recorded video that depicted the helicopter yawing to the left in response to pilot left pedal input following right yaw.
