## Discrepancy

((OF1R)) DURING AN ANNUAL INSP, 1 RT FLAP NOSE RIB WAS FOUND CRACKED.  IT IS THE RIB LOCATED DIRECTLY BENEATH THE ACTUATOR ATTACH BRACKET.  IT WAS CRACKED  IN THE RELIEF CUTOUT FOR THE FLANGES AND THROUGH THE MOST FWD NUTPLATE RIVET HOLES.  VERY INACCESSABLE AREA TO INSPECT.  YOU MUST BE LOOKING AT THIS RIB WITH THE FLANGES FACING YU TO DETECT CRACKS UNTIL THEY BECOME VERY LARGE.  RECOMMEND MAKING AN ADDITIONAL ACCESS HOLE OR USING A BOROSCOPE FOR THIS INSPECTION.
