Windham Airport
Aircraft Accident/Incident Report

Willimantic, Connecticut 06226
Wednesday, August 6, 1997 12:20 EDT

NTSB Narrative Summary Released at Completion of Accident

The student pilot flew his first two flights with another instructor. After practicing various maneuvers and while hovering at about 10 feet AGL with a new instructor, the student pilot was asked to return to their home airport to practice auto rotations. The student pilot turned the throttle to idle and the helicopter impacted the ground before the instructor could recover. The student pilot stated that he mistakenly thought the instructor requested an auto rotation from their present location, as he had done on his previous flights. No mechanical problems were reported by the instructor or the student.

NTSB Probable Cause Narrative

The student pilot misunderstood the flight instructor's instructions and reduced the engine power to idle, and the Certificated Flight Instructor's delayed remedial action.
