NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

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.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

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.
