The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
privacy data omitted Had been sitting on the ramp for several days prior to the flight. The weather was cold and rainy with heavy downpours the days preceding the flight. Upon reaching FL280 the pilot noticed the clutch on the trim system intermittently engaging. The aircraft was significantly out of trim and the elevator trim would not move. He declared an emergency and started a descent for landing. Once safely on the ground the elevator trim system was still frozen, within 10 mins the trim could be moved slightly with normal pressure and within 20 mins the trim was fully functional in manual and electric modes. Mechanics were sent to the aircraft for a safety inspection and all was normal. Once plane was back in the maintenance shop the entire system was greased and inspected and returned to service. The aircraft has flown approximately 15 hrs
Since without any issues.
