Investigator assessment
Analysis narrative
According to the pilot, he repositioned the helicopter within the landing zone after landing to use its full length for the planned departure. As he applied takeoff power, the pilot inadvertently climbed the helicopter into wires above the main rotor blades. The pilot subsequently reduced power and attempted a run-on landing to an adjacent road, but the main rotor struck a building. The helicopter rolled on its side and was substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
