Analysis

The S-76 helicopter was taxiing on its company ramp when the copilot taxied onto a grass area. During a left turn the right main wheel stuck in a soft spot and the helicopter rolled over on its right side receiving substantial damage. The ground maneuver that preceded the rollover met several of the criteria described in the FAA advisory circular for helicopter dynamic rollover.
