## Discrepancy

AIRCRAFT RETURNED TO PLATFORM AS A CONSEQUENCE THAT BEFORE TAKEOFF THE RIGHT GENERATOR FREQUENCY AND AHRS-2 WERE OUT OF SERVICE.  THE REPORT WAS DEFERRED IAW MEL 24-1-B.  DURING OVERNIGHT CHECK, THE RIGHT CSD AND OIL HEAT EXCHANGER WERE REPLACED IAW MM 24-10-01/-03, RESPECTIVELY AND THE AHRS-2 WAS TESTED IAW MM 34-21-10, BEING CORRECT.  DEFERRED REPORT WAS CLOSED.
