The NTSB's narrative final · quoted from the NTSB record
The pilot stated that he was on approach to a ridge line landing zone. He said he was passing through translational lift at 20 knots and 70 feet when a gust of wind induced a loss of tail rotor effectiveness and a resultant loss of directional control. The pilot reported that the helicopter began to spin and he could not regain directional control prior to ground contact. After the impact sequence, a ground fire erupted which consumed the helicopter. The helicopter was an early model Bell 206A and was equipped with the small tail rotor.
