The two pilots of a Colgan Air Beech 1900D were killed when it crashed shortly after take-off from Yarmouth, Massachusetts, after maintenance on 26 August last year. The NTSB interim report said elevator trim cables had just been replaced, and the FAA says instructions in the type maintenance manual have since been changed. Ambiguous instructions for the elevator trim rigging procedure are a consideration in the ongoing NTSBColgan Air investigation, says the FAA. Then on 16 October the crew of a CommutAir 1900D aborted their take-off run at Albany, New York at rotate because the elevator control appeared to be jammed. This was also the first flight after maintenance. In this case the trim wheel had been removed to give the mechanic access to the throttle mechanism, and the NTSB reports that, upon replacing the wheel, it was not indexed, so the trim was nose-down when the trim wheel was set to neutral.
