Factual narrative

On December 2, 1995, at 1505 central standard time, an Eckley Rotorway helicopter, N50235, piloted by the owner/builder, sustained substantial damage when it rolled over after start up at Salina Municipal Airport, Salina, Kansas. The non- certificated pilot reported no injuries. Visual meteorological conditions prevailed for the 14 CFR Part 91 local flight, no flight plan was filed. During a telephone interview, the pilot reported that the helicopter had been in storage for the past three years. This was to be the helicopter's first flight since taken out of storage. The pilot stated the purpose of the flight was to check the cyclic rigging. He stated that he has performed all inspections and rigging on the helicopter. The pilot stated that the cause of the accident was the over adjusting of the cycle control during the rigging procedure which caused the rollover. Review of the pilot's logbook revealed the pilot did not hold a valid medical, airman certificate, nor the student pilot endorsements required to operate the helicopter. The pilot had no recent flying experience during the past three years. The pilot also did not possess a Repairman Certificate.
