Aircraft Accident/Incident Report

Merced, California 95339

NTSB Narrative Summary Released at Completion of Accident

The pilot was on a flight test for a CFI certificate with an FAA inspector. The inspector directed the pilot/applicant to perform a practice 180-degree autorotation, terminating with a power recovery. Upon entry, at 650 feet agl, the needles split, the rotor rpm was in the green, and the engine stabilized at 2,000 RPM. During the maneuver, the inspector noted that the helicopter was apparently going to overshoot the termination point. About 50 feet agl, the pilot began deceleration and the aircraft began to settle. At that point, the inspector still had not heard the engine rpm increase. Concerned that the throttle had not been rolled on, he took the controls and attempted to open the throttle. In spite of his efforts, the helicopter continued to settle, touched down hard about 100 feet beyond the termination point, bounced once, pitched forward, and then impacted a second time. The helicopter then rolled tail over nose finally coming to rest on its right side. A postaccident inspection failed to identify any discrepancies in the engine or power controls.

NTSB Probable Cause Narrative

the pilot's misjudgement of the descent rate and his delayed throttle application.
