On September 29, 2016, about 0600 central daylight time, a Bell 407 helicopter, N361SF, impacted terrain following a loss of control while attempting to land at the Comanche Country Memorial Hospital Heliport (18OK), Lawton, Oklahoma. The pilot and 3 crew members sustained minor injuries and the helicopter was substantially damaged. The helicopter was registered to and operated by Survival Flight Inc. under the provisions of 14 Code of Federal Regulations Part 91 as a positioning flight. Visual meteorological conditions prevailed for the flight which operated on a company flight plan.
The pilot reported that he maneuvered the helicopter to align with the helipad. During the descending right turn to the helipad, the pilot input left cyclic and the helicopter was unresponsive. The pilot lost control of the helicopter and it landed hard then collided with a wall.
The helicopter was retained for further examination.
