Analysis

The pilot stated that the purpose of the flight was to check the cyclic rigging on the helicopter. This was to be the helicopter's first flight in three years since it was recently taken out of storage. After start up, the helicopter rolled over. The pilot stated that the cause of the accident was the over adjusting of the cycle control during the rigging procedure. The pilot has performed all inspections and rigging on the helicopter.

The pilot also did not possess a Repairman Certificate.
