## Discrepancy

AC RETURNED TO PLATFORM DUE TO IGNITION FAILURE IN LT ENGINE. MAINT REPLACED IGNITION BOX IAW MM 74-10-01, TESTED CORRECT. AC WAS DISPATCHED AND RETURNED TO PLATFORM AGAIN DUE TO THE SAME FAILURE. LT ENGINE WAS STARTED WITH EMERGENCY INVERTER, AND BREAKERS R2-91 AND R2-92 WERE CHECKED BUT FAILURE CONTINUED, SO FAILURE WAS DEFERRED BY MEL 74-2. AT MEX THE BREAKER B1-424 WAS REPLACED AND TESTED IAW MM 74-00-00 AND 71-00-00, ALL CORRECT. THE DEFERRED REPORT WAS CLOSED.
