## Discrepancy

WITH AP ENGAGED, AP TRIM MOTOR RAN APPROX 9 AND ONE-HALF ROTATIONS FWD AND THEN 9 AND ONE-HALF ROTATIONS AFT.  DOES THIS CONTINIOUSLY.  WITH STAB TRIM SWITCHES OFF AND MANUALLY TRIMMING, IT FELT AS IF STABILIZER WAS BINDING.  FOUND MOISTURE ON JACKSCREW.  CLEANED AND LUBED SAME.  RAN PDC BITE TEST AND SURFACE TEST FOR STAB TRIM.  OPS CKS NORMAL.
