Analysis

The helicopter was parked on a trailer between two T-hangars and under a power line. The pilot stated that he cleared the area around the helicopter; however, he did not clear the area directly over the helicopter. The pilot lifted off the trailer and impacted the power line approximately 30 feet above the ground. The pilot mentioned that at the time of the accident, "the sun was at an angle and intensity so that the wires were not visible." He also stated that the wires were not marked with red balls. The power line wrapped around the main rotor mast and partially separated one of the main rotor blades. The helicopter then entered an uncontrolled descent and impacted the ground.
