## Discrepancy

DURING REPLACEMENT OF PAN UNDER WING WALK IN THE GEAR WELL, RIB WAS FOUND CRACKED. THE WING WAS REMOVED AND FOUND SEVERAL WING ATTACHMENT BOLTS CORRODED.  BOLTS AND SPECIAL WASHERS NOT IN PROPER LOCATIONS PER PA28 MM.  (WING ATTACH).  NO SHIMS AT EITHER WING SPAR.  SEVERAL RIVETS NOT INSTALLED.  (HOLES NOT DRILLED), CHERRY MAX RIVETS THAT WERE TOO SHORT INSTALLED.  OTHER RIVETS BUCKED POORLY.  BOTH AILERON CABLES WORN, NO STRAND BROKEN, BUT REPLACED FOR PREVENTATIVE MAINTENANCE.  LEFT WING ATTACHMENT BOLTS REPLACED ONE AT A TIME.  SEVERAL FOUND CORRODED.
