An American Airlines Airbus A330-300, registration N276AY performing flight AA-719 from Rome Fiumicino (Italy) to Philadelphia,PA (USA), was enroute at FL360 over the Atlantic Ocean about 960nm eastnortheast of Gander,NL (Canada) when the crew reported a problem with flight crew oxygen supply and requested to turn around and divert to Shannon (Ireland). Oceanic Control was unable to clear the flight to Shannon due to conflicting traffic. A short time later the crew declared emergency reporting the lack of flight crew oxygen supply and performed oceanic contingency procedures to descend to 10,000 feet. After levelling off at 10,000 feet the crew advised that an emergency situation no longer existed and requested to divert to Gander, where the aircraft landed safely about 3 hours later.

A passenger reported the flight crew timed out while on the ground in Gander.

A replacement crew flew the occurrence aircraft from Gander to Philadelphia arriving at the destination with a delay of 8 hours.

On Oct 5th 2016 the Canadian TSB reported that maintenance isolated an oxygen leak at the captain's oxygen mask and replaced the mask assembly. The oxygen bottle was serviced and the system tested normally.
