Aircraft Accident/Incident Report

Alexandria Bay, New York 13607
Monday, May 11, 1998 20:30 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was receiving instruction from a flight instructor for the purpose of practicing touchdown autorotations towards attaining his instructor certificate. The pilot said that during the autorotation, the helicopter touched down hard on the left main landing gear. The left skid then separated and the helicopter rolled over to the left. The pilot said there was no mechanical malfunction with the helicopter, and the accident could have been prevented if the flight instructor had taken the controls. He said the instructor was a relatively new instructor. The pilot also stated that the flight instructor might have been hesitant to correct a more experienced pilot. The instructor reported over 440 hours of rotorcraft flight experience including, 41 hours in make and model. The pilot reported over 3,420 hours of rotorcraft flight experience, including 63 hours in make and model. Several attempts were made to contact the instructor without success.

NTSB Probable Cause Narrative

Failure of the pilot to maintain rotor rpm during practice autorotation, and the flight instructor's inadequate supervision.
