The pilot stated when interviewed the first time 2 days after the accident that the helicopter was on a trailer that had been in a hangar, but the trailer with helicopter onboard was removed from the hangar onto the ramp. He planned on lifting the helicopter off the trailer onto the ramp first, then intended on landing the helicopter onto a larger trailer. He stated that when he attempted to lift off from the smaller trailer, the rear portion of the left skid caught on the trailer and the helicopter rolled over. He submitted a report to the NTSB stating that the purpose of the flight was to perform an engine run only following an annual inspection and there was no intention to fly the helicopter. He stated in the report that during the engine run, the helicopter "vibrated the skids off the trailer, falling on side damaging main and tail rotor blades."
