Narrative:

Fuel leak/engine damage. Remarks: at FL310, 30 mins north of mia on ar-1, XA06L, the #1 fuel gauge started decreasing. A test of the fuel gauges was done and indications were normal for the test. The yoke was 10-15 degrees left indicating a heavy right wing. Autoplt was disengaged and the out of balance condition was verified. Flight engineer was sent to the cabin to visually check the wings, left primarily, for any fuel leaks. No leaks could be seen. There was approximately a 5000 pound split between the #1 and #3 tanks. #1 being lower. Executed the 'fuel quantity decreasing' procedure. Shut down the #1 engine. Contacted ATC, ZMA, and declared an emergency. Nearest suitable field was mia relative to planned flight profile. Executed all appropriate checklists for a 2 engine approach. Notified the #1 flight attendant to prepare the cabin for a possible evacuate/evacuation. Upon landing runway 9L mia, I was informed that we had a major fuel leak from the #1 engine pod. With that confirmation, I commanded an evacuate/evacuation of the aircraft with instructions not to use the left side of the aircraft and airstairs. 107 people exited through the 2 service doors in about 1 min. No injuries to passenger or crew were incurred or noted.

Title: INFLT ENG SHUTDOWN PERFORMED AFTER IT WAS DETERMINED THAT A MAJOR FUEL LEAK HAD OCCURRED BY OR IN #1 ENG.

Narrative: FUEL LEAK/ENG DAMAGE. REMARKS: AT FL310, 30 MINS N OF MIA ON AR-1, XA06L, THE #1 FUEL GAUGE STARTED DECREASING. A TEST OF THE FUEL GAUGES WAS DONE AND INDICATIONS WERE NORMAL FOR THE TEST. THE YOKE WAS 10-15 DEGS L INDICATING A HVY R WING. AUTOPLT WAS DISENGAGED AND THE OUT OF BAL CONDITION WAS VERIFIED. FE WAS SENT TO THE CABIN TO VISUALLY CHK THE WINGS, L PRIMARILY, FOR ANY FUEL LEAKS. NO LEAKS COULD BE SEEN. THERE WAS APPROX A 5000 LB SPLIT BTWN THE #1 AND #3 TANKS. #1 BEING LOWER. EXECUTED THE 'FUEL QUANTITY DECREASING' PROC. SHUT DOWN THE #1 ENG. CONTACTED ATC, ZMA, AND DECLARED AN EMER. NEAREST SUITABLE FIELD WAS MIA RELATIVE TO PLANNED FLT PROFILE. EXECUTED ALL APPROPRIATE CHKLISTS FOR A 2 ENG APCH. NOTIFIED THE #1 FLT ATTENDANT TO PREPARE THE CABIN FOR A POSSIBLE EVAC. UPON LNDG RWY 9L MIA, I WAS INFORMED THAT WE HAD A MAJOR FUEL LEAK FROM THE #1 ENG POD. WITH THAT CONFIRMATION, I COMMANDED AN EVAC OF THE ACFT WITH INSTRUCTIONS NOT TO USE THE L SIDE OF THE ACFT AND AIRSTAIRS. 107 PEOPLE EXITED THROUGH THE 2 SVC DOORS IN ABOUT 1 MIN. NO INJURIES TO PAX OR CREW WERE INCURRED OR NOTED.
