The emergency medical helicopter impacted terrain following takeoff when it began spinning around its vertical axis to a height of approximately 200-300 feet and descended without directional control. The copilot's anti-torque control pedals were found in their full forward position with a safety wire installation that would provide for forward travel of the anti-torque pedals which was contrary to specifications cited in the field approval for the pedal cover. Aircraft logbook entries show that the cover was reinstalled following a company training and evaluation flight.
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.
