What was found
THE LT AND RT FORWARD TRUNNION FITTING ASSEMBLIES WERE REMOVED TO COMPLY WITH MFG (FORWARD SIDEBRACE STUD). WHILE THE FITTINGS WERE REMOVED IT WAS NOTICED THAT THE LEFT AND RIGHT WING RIBS MFG (PN 7847504 AND 05) WERE CRACKED AT THE FORWARD OUTBOARD FLANGE OF THE RIBS. THIS FLANGE IS UNDER THE TRUNNION FITTING ASSEMBLY AND CANNOT BE SEEN WITHOUT REMOVAL OF THE TRUNNION FITTING. THIS IS THE THIRD TIME THESE CRACKED RIBS HAVE BEEN FOUND. SUGGEST PERIODIC INSPECTION IN THIS AREA.
