Investigating agency: NTSB
The helicopter was returning from a sight-seeing flight with two pilots and two passengers aboard. During approach to land, at 100 to 150 feet above ground level, at a high gross weight, high-density altitude, and low wind condition, the pilot-in-command allowed the helicopter to slow and enter a high sink rate. In attempting to recover from the sink rate, loss of tail rotor effectiveness occurred and the helicopter started to spin. The safety pilot took control and stopped the spin, but the helicopter landed hard.

Probable Cause: Settling with power and a loss of tail rotor effectiveness. Factors were an improperly planned approach by the pilot in command, high density altitude, and inadequate supervision by the safety pilot.


FAA register: 2.
