Delta B763 at New York on Feb 27th 2014, flaps did not retract

A Delta Airlines Boeing 767-300, registration N188DN performing flight DL-408 from New York JFK,NY (USA) to Brussels (Belgium) with 186 people on board, was climbing out of New York's runway 31L when the crew reported they had flaps disagree message and wanted to maintain present speed and level off at 9000 feet. While working the relevant checklists the crew advised there was a distinct possibility they might have blown a tyre on departure and requested a runway inspection, they did have a smell of burned rubber and now were having a problem with the trailing edge flaps. While being vectored within the departure controller's airspace at 9000 feet the crew indicated that the smell in the back of the cabin was increasing. ATC subsequently advised nothing had been found on the runway. The crew advised they needed to burn off some fuel and would probably land overweight, no fuel dump possible. The crew subsequently returned to JFK Airport for a safe landing on runway 31L.

The rotation DL-408/DL-409 was cancelled.
