## Discrepancy

AIRBORNE A/T CLICKED OFF, DFGS ALT WINDOW BLANKED, AND FMS SCRATCH PAD SHOWED CADC NR 1 FAILED.  USED CADC FAIL CHECKLIST.  ON LEVEL OFF NR 1 ALT WAS 600 FT HIGHER THAN STBY.  BECAUSE OF INDICATION IF INTERMITTENT FAILURE FROM   BOTH CADC COMP, RETURNED TO CVG.  REPLACED CADC NR 1 AND CADC NR 2.  OPS AND LEAK CHECKED SYS PER AMM 34-11-00-201-1.  RAN RT 1 AND 2, BOTH OK.
