Aircraft involved
Probable cause & findings
The non-certificated pilot’s failure to maintain control of the unregistered helicopter during landing.
Factual narrative
The pilot/owner was operating the unregistered experimental helicopter in his back yard, when he attempted to lift the skids off the ground “a few inches.” When the pilot set the helicopter back down on the ground, it rolled over onto its left side resulting in substantial damage to the fuselage. The main rotor system, including the controls for the cyclic were also damaged from impact. Though the pilot held a private pilot certificate with a rating for airplane single-engine land, he was not certificated to act as a pilot in helicopters.
