Accident Overview
After completing a local photographic flight, the pilot of a helicopter conducted an approach to a hover landing near the approach end of Runway 17. Following clearance to cross the runway and proceed to the intended parking area, the pilot initiated forward movement and began a climb. During this maneuver, the pilot perceived a partial power loss and immediately commenced a hovering autorotation.
Sequence of Events
The helicopter touched down with forward speed, slid to a stop, and then rocked backward and to the left. The dynamic impact resulted in damage to both the main rotor blades and the tail rotor blades.
Post-Accident Findings
A post-accident engine run was performed; however, no reason could be identified for the reported power loss. The prevailing wind was from 340 degrees at 10 knots, with the pilot reporting gusts up to 20 knots. The density altitude for the location was calculated to be 7,300 feet.
Damage Assessment
Damage was limited to the main and tail rotor blades. No other structural or component damage was documented.
