## Discrepancy

AIRCRAFT RETURN TO PLATFORM DUE TO LOSS OF FLIGHT DIRECTOR BUS.  THE DFGC BRAKERS WERE RESET AND THE CODE FAIL INDICATES CADC NR 1 AND LEADING ANGLE TRANSMITTOR NR 1 DAMAGED.  THE DFGC NR 1 WAS REPLACED IAW MM 22-01-01.  DURING OVERNIGHT SERVICE BOTH DFGC WERE TESTED IAW MM 22-01-03, ALL CORRECT.
