A United Airlines Boeing 767-300, registration N670UA performing flight UA-904 from Newark,NJ (USA) to Istanbul (Turkey), was enroute at FL350 about 300nm east of St. John's,NL (Canada) when the crew requested to divert and turned to St. John's due to a maintenance issue. About 30 minutes later the crew declared emergency reporting a clogged fuel filter, the aircraft descended to FL220. On approach to St. John's the crew reported they had no emergency issue on hand right now though they had declared emergency earlier. The aircraft descended early reaching 6000 feet about 90nm out and 3000 feet 35nm out. The aircraft landed safely on St. John's runway 11 about 90 minutes after the request to divert.

A replacement Boeing 767-300 registration N676UA reached Istanbul as flight UA-1755 with a delay of 28 hours.

The incident aircraft positioned to Newark as flight UA-6650 on Dec 24th and is currently estimated to resume service in the late evening of Dec 26th.

The Canadian TSB reported on Jan 4th 2013, that the crew received an intermittent "L ENG FUEL FILTER" EICAS message and decided to divert to the nearest suitable airport St. John's and declared emergency due to an overweight landing. Maintenance checked the left engine's fuel filter but found nothing wrong. Nonetheless the filter and the pressure differential switch were replaced.
