## Discrepancy

(CAN) RIVETS THAT ATTACH FITTING TO FORWARD SPAR WERE SHEARED. MOST RIVETS, 10 IN ALL, SHOWED SIGNS OF RINGS AROUND SHANKS AT FITTING/SKIN SEAM. ONE RIVETS WAS SHEARED IN HALF. THERE WERE NO EXTERNAL SIGNS OF ANY PROBLEMS. THE STABILIZER IN QUESTION CAME IN FOR SKINS TO BE REPLACED. HAVING RECOLLECTED A PREVIOUS SDR ON THIS MATTER, WE DECIDED TO CHANGE ALL THE RIVETS 'JUST CAUSE' IN CASE THERE WAS A PROBLEM. THE RINGS AROUND THE SHANKS OF THE NON-SHEARED RIVETS MAY BE FROM WHEN THE RIVETS WERE ORIGINALLY INSTALLED. THEY MAY HAVE SOME STRESSES IMPOSED ON THEM. I CAN'T TELL JUST BY LOOKING AT THEM.
