## Discrepancy

(CAN) DURING THE ROUTINE COMPLETION OF CF1981-35 SITES NR 1 AND NR 2, A SMALL CRACK WAS DISCOVERED ON THE LOWER RT, IB BATHTUB FITTING. THE CRACK APPEARED TO START ON THE FEATHERED EDGE AT THE CENTER OF THE RADIUS AND PROPOGATE TOWARD THE MATING SURFACE OF THE FITTING FOR A DISTANCE OF APPROXIMATELY 0.164 INCH.  MFG WAS CONSULTED AND A REPAIR WAS GENERATED THROUGH THEIR REPAIR DESIGN OFFICE. IT CONSISTED OF BLENDING OUT THE CRACK TO THE SPECIFIED DIMENSIONS, PERFORMING FPI TO ENSURE ALL THE CRACK WAS REMOVED AND SURFACE TREATING THE ALUMINUM TO PREVENT CORROSION. THE WING BOLT WAS REINSTALLED IAW SIRM AND THE AIRCRAFT RELEASED FOR SERVICE.
