## Discrepancy

ON A POSITION LEG, DURING CLIMB THROUGH FL390 TO FL400.  EXPERIENCED A FROZEN ELEVATOR TRIM.  BOTH THE ELECTRICAL & MANUAL TRIM WERE AFFECTED.  RAN THE ABNORMAL CHECKLIST & DIVERTED.  DURING DESCENT PASSING FL 280,  STARTED TO REGAIN SOME MOVEMENT OF THE TRIM WHEEL & MOVEMENT FURTHER FREED UP, AND DESCENDED.  AFTER LANDING, THE ELECTRICAL TRIM WAS SLOW & MANUAL MODE WAS DIFFICULT TO MOVE.   FOUND BOTH ELEVATOR TRIM ACTUATORS CORRODED AND WORN BUSHINGS & SEALS.  BOTH ACTUATORS REPLACED SYS RIGGED & OPS CHECKED OK.  PERFORMED SATISFACTORY.
