On July 6, 2005, about 2030 eastern daylight time, a Robinson R44, N90SG, registered to Red Stone Helicopter Sales & Leasing LLC, collided with a palm tree then the ground while landing at a private helipad near St. Cloud, Florida. Visual meteorological conditions prevailed at the time and no flight plan was filed for the 14 CFR Part 91 local, personal flight from the private helipad. The helicopter was substantially damaged and the private-rated pilot, the sole occupant, sustained minor injuries. The flight originated about 1900, from the private helipad. The pilot stated that after departure the flight proceeded to his property nearby, then he elected to return to the helipad where the flight departed. Upon approach to the helipad he noted a horse trailer obstructed one side of the helipad and a mowing trailer obstructed the other side of the helipad. He hovered over the top of both then decided to perform a 160 degree pedal turned to the left. He reported that he "lost my focus on a palm tree and consequently struck the tree with [the] tailboom which caused a main rotor strike. Hence the accident."
