Narrative:
In landing confign, elevator controls were unresponsive -- both pushing forward and pulling back with normal input. Controls seemed hard like excessive out of trim stabilizer. Unable to move without heavy pull or push. Used stabilizer trim (electric) to keep aircraft in trimmed condition. Landing normal. Callback conversation with reporter revealed the following information: associated with 199479: upon callback the captain could not define any system disorder except to say the aircraft was 'heavy' on the controls and that the thumb switch was used principally to run the stabilizer to maintain trim or change pitch. This was written up in logbook and all he knows is that the aircraft was OTS for 2 days after that.

Title: ACFT EQUIP PROBLEM MAKES IT DIFFICULT FOR FLC TO HAND FLY APCH IN LNDG CONFIGN.
Narrative: IN LNDG CONFIGN, ELEVATOR CTLS WERE UNRESPONSIVE -- BOTH PUSHING FORWARD AND PULLING BACK WITH NORMAL INPUT. CTLS SEEMED HARD LIKE EXCESSIVE OUT OF TRIM STABILIZER. UNABLE TO MOVE WITHOUT HVY PULL OR PUSH. USED STABILIZER TRIM (ELECTRIC) TO KEEP ACFT IN TRIMMED CONDITION. LNDG NORMAL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ASSOCIATED WITH 199479: UPON CALLBACK THE CAPT COULD NOT DEFINE ANY SYS DISORDER EXCEPT TO SAY THE ACFT WAS 'HVY' ON THE CTLS AND THAT THE THUMB SWITCH WAS USED PRINCIPALLY TO RUN THE STABILIZER TO MAINTAIN TRIM OR CHANGE PITCH. THIS WAS WRITTEN UP IN LOGBOOK AND ALL HE KNOWS IS THAT THE ACFT WAS OTS FOR 2 DAYS AFTER THAT.
