## Discrepancy

DURING ANNUAL INSPECTION, INTERGRANULAR CORROSION WAS FOUND IN ANGLE REINFORCEMENT AT RT WING SPAR BUTT WHERE SPAR BOLTS TO FUSELAGE SPAR CARRY-THROUGH.  DIFFICULT AREA TO INSPECT WITHOUT REMOVAL OF COCKPIT HEADLINER.  SUBMITTER STATED IMPROPER HEAT TREATMENT WHEN MANUFACTURED.  RECOMMENDATION:  AGING AIRCRAFT REQUIRE MORE DETAILED INSPECTION IN DIFFICULT TO SEE AREAS.  SIDE NOTE:  A PAIR OF PLIERS WERE FOUND INSIDE A VOID IN THE RIGHT WING.  RUST OF PLIERS INDICATE IT HAD BEEN THERE A LONG TIME.
