Probable cause

The pilot's inadequate compensation for wind conditions, his failure to arrest the descent rate in a timely fashion, and the selection of unsuitable terrain on which to practice autorotations.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

In his written statement, the safety pilot reported that the pilot entered a simulated forced landing with the intention of performing a power recovery. He said the pilot started a 'flare' at about 50 feet above the ground. He further reported that at about 20 feet above the ground, a gust of wind caused the helicopter's descent to accelerate. The safety pilot then joined the pilot in trying to regain control. He said the rate of descent was reduced. The safety pilot reported that the aircraft continued its descent with one skid on a 'one foot rock built up area.' The safety pilot said '...the aircraft quickly (and without any way to recover) tipped over on its side (left).' The safety pilot said that he thought they (he and the other pilot) had recovered at '1-2 foot of height' but the raised rock area caught the skid causing the aircraft to rollover.
