Narrative:
During flap retraction from 5 degrees to 2 degrees; amber leading edge flap light remained on. Visibility inspection confirmed #5 leading edge device on right wing extended. Decision was made to divert mco (original flight plan fpo-bwi) because of fuel and altitude considerations. With ATC concurrence fuel was dumped. This was necessary to arrive at mco at maximum landing weight. When flaps were extended on approach, all flap and leading edge device indications were normal. Approach and landing were normal. Supplemental information from acn 144161. Visibility inspection on post flight found fuel access door open and locked. Company maintenance at mco released aircraft after functional test of flaps and slats.

Title: ACR FLT DIVERTS TO ALTERNATE ARPT AFTER LEADING EDGE SLAT FAILS TO RETRACT AFTER TKOF.
Narrative: DURING FLAP RETRACTION FROM 5 DEGS TO 2 DEGS; AMBER LEADING EDGE FLAP LIGHT REMAINED ON. VIS INSPECTION CONFIRMED #5 LEADING EDGE DEVICE ON R WING EXTENDED. DECISION WAS MADE TO DIVERT MCO (ORIGINAL FLT PLAN FPO-BWI) BECAUSE OF FUEL AND ALT CONSIDERATIONS. WITH ATC CONCURRENCE FUEL WAS DUMPED. THIS WAS NECESSARY TO ARRIVE AT MCO AT MAX LNDG WT. WHEN FLAPS WERE EXTENDED ON APCH, ALL FLAP AND LEADING EDGE DEVICE INDICATIONS WERE NORMAL. APCH AND LNDG WERE NORMAL. SUPPLEMENTAL INFO FROM ACN 144161. VIS INSPECTION ON POST FLT FOUND FUEL ACCESS DOOR OPEN AND LOCKED. COMPANY MAINT AT MCO RELEASED ACFT AFTER FUNCTIONAL TEST OF FLAPS AND SLATS.
