## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED ON DESCENT INTO CLT DUE TO A STRONG ELECTRICAL SMELL, FLIGHT CREW DONNED OXYGEN MASKS AND LANDED SAFELY AT CLT WITHOUT FURTHER INCIDENT. FLIGHT CREW REPORTED THAT THE SMELL DISAPPEARED AFTER ENGINE SHUTDOWN. MAINTENANCE DETERMINED THE SOURCE OF THE SMELL WAS DUE TO THE FAILURE OF THE #2 FLIGHT MANAGEMENT AND GUIDANCE COMPUTER (FMGC) WHICH WAS REPLACED PER AMM 22-83-34. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED.
