Probable cause

The inadvertent contact of a lift strap with the tail rotor during external load operations, which resulted in a forced landing and subsequent collision with terrain. A factor in this accident was the gusty wind conditions.

Sequence of events

Analysis

The pilot was conducting external load operations, when a gust of wind blew the lifting strap into the tail rotor. The helicopter began to shudder, and rotate to the left. The pilot entered an autorotation; however, during landing, the helicopter rolled over onto its left side. Winds reported at an airport located about 4 miles east-southeast of the accident site, about the time of the accident, were from 200 degrees at 17 knots, with 23 knot gusts.
