Probable cause

The pilot's failure to properly manipulate the throttle control to maintain engine/rotor RPM and his decision to enter an autorotation (forced landing). His eagerness to land and lack of total experience were factors in the accident.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

While enroute to his first destination of a solo instructional flight, the recently rated pilot observed the helicopter's engine RPM sightly below the normal range. He was unable to increase the RPM and elected to enter an autorotative descent to the ground. During the autorotation, he observed electrical power lines in his flight path and maneuvered to avoid them. The helicopter collided with the ground seriously injuring the pilot.
