What was found
WHILE CLIMBING THROUGH FL 390 WE RECEIVED PIT TRIM ANNUCIATION ON BOTH PFDS. THE TRIM WHEEL WAS TRYING TO TRIM BUT WAS BINDING AND NOT MOVING AND HAD AN AUDIBLE BINDING SOUND. NEITHER ELECTRIC OR MANUAL TRIM WERE WORKING. THE TRIM NEVER COULD GO PAST THE WORD "DOWN" ON THE TRIM RANGE INDICATOR. ON THE GROUND TRIM WILL GO ALL THE WAY TO THE WORD "TRIM", THE NORMAL RANGE.
