Aircraft Accident/Incident Report

Linden, New Jersey 07036
Friday, January 3, 1997 13:30 EST

NTSB Narrative Summary Released at Completion of Accident

The pilot reported 'While practicing full autorotations I attempted to demonstrate a 180 degree autorotation to the ground to the owner of the aircraft, who is himself is a private helicopter pilot. While turning to the touchdown spot I noticed the RPM decaying, I attempted to recover the RPM by entering the flare early and prior to completing the turn, however the helicopter mushed through the flare and impacted the ground at a high rate of descent, and caused damage to the rear cross tube. After the immediate impact the helicopter became airborne again and collective application was used to conclude the auto with the helicopter in an upright position.'

NTSB Probable Cause Narrative

the pilot allowing the rotor RPM to decay and his failure to take remedial action in time to recover the autorotation.
