An ABX Air Boeing 767-300 freighter, registration N220CY performing freight flight GB-984 from London Heathrow,EN (UK) to Chicago O'Hare,IL (USA), was enroute at FL300 about 100nm westsouthwest of Cork (Ireland) when Shannon Center (Ireland) called the crew advising them Shanwick had cancelled their onward routing following a message received from the flight deck, that they had lost one of their navigation systems and were probably returning to Heathrow, being unable to go Oceanic if they couldn't restore the system's function. The crew at this time was still working their checklists and about to decide what to do, the information from Shanwick accelered the decision to return to Heathrow. The aircraft descended to FL150 to burn off fuel and landed safely on Heathrow's runway 09L about 2:40 hours after departure.
The aircraft is still on the ground in Heathrow about 5 hours after landing.
