NTSB summary
HISTORY OF FLIGHT On April 13, 2006, at 1022 central daylight time, a Messerschmitt-Bolkow-Blohm BO 105LS A-3, N202LF, operated by County Rescue Services, Inc., as an emergency medical service (EMS) helicopter, received substantial damage on impact with terrain following a reported loss of directional control during takeoff from the operator's heliport, GRBC Rescue Heliport, Green Bay, Wisconsin. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 91 flight was not operating on a flight plan. The pilot was fatally injured. The local flight was originating at the time of the accident. The pilot was conducting a maintenance test flight to check the VOR receiver that had been recently installed on the helicopter. Witnesses reported that as the helicopter lifted off the dolly located on the helipad (107 feet by 75 feet, concrete), it started rotating around the helicopter's vertical axis. They stated that the helicopter reached an altitude of approximately 200-300 feet above ground while still rotating. The helicopter stopped spinning and started "a rapid descent". The witnesses stated that the helicopter was descending at a speed "far greater than was reasonably possible" for a normal landing. The witnesses reported the helicopter struck the ground in an upright position. PERSONNEL INFORMATION According to Federal Aviation Administration (FAA) records, the pilot was issued a commercial pilot certificate with airplane single-engine land and rotorcraft-helicopter ratings on June 18, 2004. The pilot also held an instrument rating for airplanes
Probable cause
The pilot's inadequate preflight check of the flight controls prior to takeoff and the directional contol not possible by the pilot. Additional causes were the improper installation of the anti-torque pedal cover by company personnel which blocked the flight control system.
