## Discrepancy

WHILE AT CRUISE, FL 400, THE RT WING OVHT LIGHT ILLUMINATED. THE CREW ACCOMPLISHED THE APPROPRIATE CHECKLIST. THE NR 3 AND NR 4 FIRE LOOPS FAILED FIVE MINUTES LATER.   DISPATCH AND TECH CENTER NOTIFIED.   AN ACRID ODOR WAS DETECTED BY THE CREW, SHORTLY AFTER THIS. SMOKE WAS SEEN COMING FROM BEHIND THE P-6 CIRCUIT BREAKER PANEL, FOLLOWED BY A SMALL FIRE IN THE FIRE DETECTION CARD FILE.  THIS SDR TO REMAIN OPEN UNTIL CAUSE IS DETERMINED.
