## Discrepancy

WHILE PERFORMING AN A-D INSPECTION FOUND 8 LOOSE RIVETS IN THE FORWARD RIVET LINE OF THE ATTACHMENT PIVOT FITTING PN 45A21183-11 ON THE BOTTOM OF THE HORIZONTAL STABILIZER.  IT IS SUSPECTED THAT THE LOOSE RIVETS WERE CAUSED BY FATIGUE AND AGE.  RECOMMEND INSPECTING AREA THOROUGHLY AT EACH INSPECTION.  RECOMMEND CONTACTING MFG FOR REPAIR OPTIONS.  THIS IS THE 3RD AIRCRAFT IN A ROW THAT THESE SAME RIVETS HAVE BEEN LOOSE OR MISSING.  (K)
