## Discrepancy

SMOKING RIVETS IN LEADING EDGE SKIN UPPER SEAM.  EVERY COUNTERSUNK HOLE FROM WS 35 TO WS 141 WAS FRETTING AGAINST THE RIVET HEAD.  SAME CONDITION TO SAME EXTENT ON BOTH WINGS.  IT APPEARS THE SKIN WAS COUNTERSUNK TOO DEEPLY.  SAME CONDITION TO LESSER EXTENT FOUND ON OTHER AC IN THE FLEET.  MFG ADDRESSES THIS ISSUE IN THE SRM WITH (2) TYPES OF REPAIR DEPENDING ON SEVERITY OF DAMAGE.  (K)
