Accident Number: ERA22LA140
Date and Time: March 1, 2022, 11:20 Local
Registration: N786SH
Aircraft: ROBINSON HELICOPTER COMPANY R22 
Aircraft Damage: Substantial
Defining Event: Dynamic rollover
Injuries: 1 Minor, 1 None
Flight Conducted Under: Part 91: General aviation - Instructional

Analysis

The flight instructor and his student were performing maneuvers as part of a flight lesson. About 40 minutes into the flight, while attempting a left pedal turn, the helicopter descended just enough to touch the left rear skid, which surprised the student, who then added right lateral cyclic control. The helicopter’s right skid dug in the ground, and the helicopter rolled over on to its right side, which resulted in substantial damage to the fuselage and main rotor blades.

The helicopter manufacturer’s flight maneuvers guide advised that a 5-foot hover should be used for all taxi and hover operations, and a minimum 5-foot hover was the policy of the flight school.

After the accident, the flight school had discussions with all their helicopter instructors to emphasize the need to maintain proper height above the ground, the need to closely guard the controls while instructing, and the need for improved awareness of the capabilities and experience of the students.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The student pilot's unstabilized hover, which resulted in ground contact and a dynamic rollover. Contributing to the accident was the flight instructor's inadequate supervision of the student and his delayed remedial action.
