Boire Field Airport
Aircraft Accident/Incident Report
Nashua, New Hampshire 03063
Friday, July 22, 2005 10:30 EDT
NTSB Narrative Summary Released at Completion of Accident
The purpose of the flight was to give a student an introductory flight. After conducting a local flight, they returned for "hover work" at the airport and then air taxied to a point just short of a runway. While waiting to cross the runway, the instructor placed the helicopter in a hover and had the student try to hold the helicopter steady while he kept his hands on the controls. The student then "pulled the controls" from his hands, and moments later, the instructor realized that the student had let go of the controls. The helicopter then "rolled hard left, very fast" and the instructor could not regain control. The main rotor blades then struck the ground. Examination of the helicopter revealed no evidence of any preimpact malfunctions.
NTSB Probable Cause Narrative
The flight instructor's failure to maintain aircraft control during a introductory flight and his inadequate remedial actions.
