Incident Overview

A pilot reported an accident that occurred while conducting deer capture operations. During a low-altitude tail-low flare maneuver, the helicopter's tail rotor blades struck a rock outcropping as the aircraft maneuvered around a knoll. The impact caused the helicopter to rotate 270 degrees to the right before contacting the ground and rolling over onto its left side.

Post-Impact Conditions

There was no post-crash fire. The pilot reported no mechanical anomalies with the helicopter prior to or during the flight, indicating that the accident was not due to a mechanical failure.

Operational Context
