The NTSB last week released a preliminary report on the April 9 accident involving an Airbus AS350 B3 helicopter that crashed shortly after takeoff from an Albuquerque, N.M. hospital helipad. The pilot reported he did complete all pre-takeoff hydraulic checks and that after liftoff he commanded a slight left turn. The helicopter, however, kept turning and entered a spin. The pilot said the pedals were jammed or locked in the neutral position.
