## Discrepancy

FLIGHT 8299, ENROUTE AFW-TUL/ DISCREPANCY: DURING APPROACH INTO TULSA, THE CREW RECEIVED A #2 ENGINE FIRE WARNING. THE #2 ENGINE WAS SHUTDOWN AND #2 ENGINE FIRE BOTTLE WAS ACTIVATED. AN EMERGENCY WAS DECLARED. THE AIRCAFT LANDED WITHOUT FURTHER INCIDENT. MAINTENANCE IS CURRENTLY TROUBLESHOOTING. A SUPPLEMENTAL SDR WITH CORRECTIVE ACTION WILL BE SUBMITTED. THIS IS A SUPPLEMENTAL TO PREVIOUSLY SUBMITTED SDR COEA2019110113816 FOR CORRECTIVE ACTION: MAINTENANCE TROUBLESHOT, REPLACED LH/RH ENGINE FIRE BOTTLES, CARTRIDGES AND THE #2 ENGINE FIRE DETECTION UNIT. DISCOVERED THE #2 ENGINE FIRE SENSING ELEMENT AT 34WD CAUSING SHORT CIRCUIT. REPLACED THE ELEMENT. OPS CHECK OF FIRE DETECTION SYSTEM GOOD.
