## Discrepancy

AIRCRAFT WAS NOT GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO MIA DUE TO THE FLIGHT CREW REPORTING A FLIGHT CONTROL FLAP SYSTEM 2 FAULT DISPLAYING ON RETRACTION FROM FLAPS 1. THE AIRCRAFT LANDED SAFELY AT MIA WITHOUT FURTHER INCIDENT. MAINTENANCE ACCOMPLISHED A REVIEW OF THE POST FLIGHT REPORT WHICH SHOWED SFCC-2 F/CTL FLAP 2 FAULTS. MAINTENANCE ACCOMPLISHED TSM 27-51-00-810-845 AND ALL TESTS PASSED. MAINTENANCE DID NOT IDENTIFY A SPECIFIC PART THAT WOULD HAVE CAUSED THE FAULT REPORTED BY THE FLIGHT CREW.
