Jetstream 4100, G-MAJM

Summary:

While climbing through 9,000 feet on a scheduled passenger flight from Aberdeen to Newcastle, the aircraft experienced a sharp pitch change as the autopilot was engaged. When the autopilot was disengaged, pitch control was found to be very limited. Control improved during the descent for a precautionary landing at Aberdeen, and was completely restored upon touchdown. The captain believes that failure to ensure proper de-icing prior to departure had permitted ice to remain on the horizontal tail surfaces and that a further accumulation in flight caused the elevator to become jammed.
