## Discrepancy

(CAN) DURING SCHEDULED MAINTENANCE WHEN ACCOMPLISHING SB SB84-32-100 ON THE LT NACELLE, THE 2 LOWER OTBD SECURING BOLTS WERE FOUND MISSING FROM THE MLG ALTERNATE EXTENSION CAM ASSEMBLY, PN 48510-1, AIPC 32-34-26, FIG 1-10.  THE MISSING BOLTS WERE PN NAS6203-4, AIPC 32-34-26, FIG 1-20.  PHOTOS OF THE REMOVED CAM ASSY SHOW EVIDENCE THAT THESE 2 BOLTS WERE NEVER INSTALLED.  THIS IS THE SECOND REPORT OF THESE 2 BOLTS FOUND MISSING.
