NTSB narrative
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.
Probable cause
The flight instructor's failure to maintain aircraft control during a introductory flight and his inadequate remedial actions.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
