## Discrepancy

FOUND A CRACKED HORIZONTAL STAB PIVOT BOLT FITTING ASSY. WHICH WAS POSSIBLY CAUSED BY IMPROPER INSTALLATION OF THE LOWER SUPPORT CLIP.  UPON REMOVING THE LOWER SUPPORT TEE CLIP WE NOTICED THE HOLES WERE ELONGATED A LITTLE SO WE REQUESTED FROM MFG STRUCTURES ENGINEERING TO UPSIZING THE ORIGINAL BLUE PRINT FASTENERS FROM HL18PB5-XX TO HL18PB6-XX WHICH TOOK CARE OF THE ISSUE WE FOUND.  INSTALLED NEW HORIZONTAL PIVOT BOLT FITTING, PN 6631102-15 AND NEW LOWER CLIP ASSEMBLY, PN'S 6631202-8 AND 6631202-7.
