What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On March 28, 2000, at 0959E, DHC-8, s/n 187, registered as N822EX, landed at pit after the crew reported the elevator manual trim had jammed in cruise flight. The electric trim system continued to operate and the autopilot was disengaged. The checklist was followed and the aircraft landed at pit and taxied to the gate without incident. Maintenance checked the system and found that the manual trim actuator had water in the jack screw and that the manual and electric trim both operated properly. The manual trim jack screw was lubed per the mm and the aircraft was returned to service. Investigation by desk audit and closed.
