## Discrepancy

DURING BOTH OB SLAT REMOVALS  FOR RESKINS  WERE NOISES  INSIDE LE, S.  UPON INVESTIGATION, FOUND 3 EA BOLTS IN THE RT OB AND 1 EA IN LT OB LE,S.  DETERMINED TO BE FROM NR 1 ENG THRUST BRG SUPPT PLATE, WHICH IS SUPPOSED TO HAVE 8 EA BOLTS.  ENG MFG REQUESTED ENG TO BE REMOVED AND SENT TO MFG FOR TEARDOWN AND INVESTIGATION.  OUT OF 8 BOLTS INSTALLED, ONLY 2 EA REMAINED INTACT ON THE ENG, THEREFORE 6 EA BOLTS WERE IN THE AIRCRAFT SYSTEM TO BE LOCATED.  AT SENDING OF SDR, HAVE LOCATED 4 EA BOLTS, 2EA STILL MISSING.  THIS AREA OF ENG CAN NOT BE SEEN COMPLETELY.  VIA BOROSCOPE ONLY, CAN  5 OR 6 BOLTS BE VISUAL CKD.
