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." ## Factual narrative On June 5, 2001, about 1630 central daylight time, an Enstrom F28A, N9565, registered to a private individual, rolled over while lifting off a trailer at the Double Springs-Winston County Airport, Double Springs, Alabama.
