What was found
DURING SB INSPECTION OF NR 1 AND NR 5 LEADING EDGE SLAT ACTUATOR SUPPORT FITTINGS, FITTINGS WERE REMOVED TO REPLACE ATTACH HARDWARE. CORROSION WAS FOUND AT BOTH POSITIONS SEVERE ENOUGH TO REQUIRE REPAIR. SUBSEQUENT INSPECTION UNDER REMAINING FITTINGS REVEALED CORROSION AT NR 3 POSITION NOT SERIOUS ENOUGH TO REQUIRE REPAIR. SUGGEST SPECIAL ATTENTION TO SEALING PRIMING AND CORROSION PREVENTION IN ACTUATOR SUPPORT FITTINGS.
