## Discrepancy

AFTER T/O ON SLAT RETRACTION HAD KRUEGER FAULT.  RAN APPROPRIATE CHECKLISTS AND RTB.  PERFORMED BITE DISPLAY OF BOTH SFCC'S AND FOUND ALL OF THE FAULT BALLS FOR THE NR 1 UNIT LIGHT.  THAT FAULT CODE CORRESPONDS WITH BAD SFCC REF AMM 27-80-00.    IND  INSPECTED THE LT AND RT KRUGER FLAPS AND SWITCHES,  ALSO OPERATED KRUGER FLAPS THRU SEVERAL  CYCLES AND THE OPERATION WAS NORMAL. REPLACED THE NR 1 SFCC AND NR 2 SFCC PER M/M 27-51-18-04, OPS TEST WAS GOOD. ALSO PERFORMED AN LLM TEST PER M/M 22-40-00-05, TEST WAS GOOD.
