## Discrepancy

DURING DAILY INSPECTION THE P/C AIR SENSE LINE WAS FOUND TO BE DAMAGED BEYOND LIMITS. THE DAMAGE WAS CAUSED BY THE THREADED PORTION OF A SCREW RUBBING AGAINST THE LINE. THE SCREW ATTACHES TWO CLAMPS TOGETHER AS REQUIRED BY CEB 1198. THE CLAMPS (P/N 6749387-03 OR MS9825-03) FIT LOOSELY AND SLIDE CAUSING CONTACT.
