Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot not maintaining a proper descent rate and his delayed remedial action.

Analysis

During a practice autorotation, a high descent rate developed. The instructor pilot added power but the helicopter still landed hard enough to substantially damage the helicopter.

Factual narrative

On July 3, 1994, at about 1430 hours mountain daylight time, a Hughes 369HS helicopter, N9029F, made a hard landing during a practice autorotation at Salt Lake City Airport #2. Visual meteorological conditions prevailed at the time and no flight plan was filed for the local training flight. The helicopter was substantially damaged, but neither the pilot or the flight instructor were injured.

The pilot reported that he was preparing for a part 135 check ride and was practicing autorotations with the company check pilot. An autorotation was started at about 500 to 600 feet above the ground. At about 100 to 150 feet above the ground, the instructor pilot realized that they were descending too fast.

He added power to slow their descent but the helicopter landed hard, damaging the skids and the tail boom.
