Reid-Hillview Airport
Aircraft Accident/Incident Report

San Jose, California 95148
Saturday, May 16, 1998 10:48 PDT

NTSB Narrative Summary Released at Completion of Accident

The flight instructor and the commercial rated pilot were practicing slope landings. The student stated that as she set the helicopter down it didn't feel right, and she attempted to abort the landing by pulling in full collective. The helicopter became airborne and the main rotor rpm decreased to the point where the low rotor rpm horn and light were activated. The flight instructor reported that he took the controls and recovered the rotor rpm to 92 percent. He attempted to cushion the landing but the helicopter landed hard on the forward portion of the left skid. The left skid tip impacted the berm and the helicopter rolled onto its left side. There was no report of prior mechanical malfunctions.

NTSB Probable Cause Narrative

The student pilot's failure to maintain adequate rotor rpm, and the flight instructor's inadequate supervision of the flight.
