Analysis

The pilot stated that after lifting off a platform to a 3-5 foot hover with all engine indications in the green and the governor on, the engine experienced a loss of power and began descending. The helicopter had drifted to the left a bit off the dolly and one of the skids contacted the dolly and the helicopter rolled onto its left side but came to rest on its right side. The pilot had the helicopter recovered and placed back in his hangar before NTSB or FAA notification. Numerous attempts were made by the NTSB investigator-in-charge to gain access to the hangar for the purpose of removing the engine from the helicopter for an attempted engine run; the pilot/owner did not respond to these attempts. Review of the NTSB Pilot/Operator Aircraft Accident Report form submitted by the pilot revealed that the yes and no blocks were marked in the area titled, "Mechanical Malfunction Failure." According to a preliminary police report, after being notified by an anonymous phone call, they arrived at the airport, opened the hangar, and noted the odor of an alcoholic beverage coming from inside the helicopter. Examination of the helicopter while it was in the hangar was performed by an FAA airworthiness inspector. The inspector reported that the helicopter sustained substantial damage.
