DURING CLIMB OUT, THE ELEVATOR TRIM WOULD NOT TRIM FWD AS NEEDED. AIRPLANE WAS BEING HAND FLOWN AT THE TIME.

ONCE SPEED WAS SLOWED, CONTROL FORCES BECAME MORE MANAGEABLE. UPON TAXI IN TRIM WAS STILL JAMMED. MAINTENANCE ADVISED TO REGREASE ACTUATORS. GREASED ACTUATORS. OPERATIONAL CHECK OF MANUAL AND ELECTRIC ELEVATOR TRIM GOOD. WORK DONE IAW MM CH 12-21-01, 27-32-02.
