A Norwegian Air Shuttle Boeing 787-800, registration LN-LNH performing flight DY-7019 from Paris Charles de Gaulle (France) to New York JFK,NY (USA) with 294 people on board, was enroute at FL380 about 400nm west of Shannon (Ireland) when the crew decided to shut the #1 engine (Trent 1000, left) down and declared PAN due to low engine oil quantity. The aircraft turned around, drifted down to FL140, dumped fuel and diverted to Shannon for a safe landing on runway 24 about 70 minutes later.
The airline reported the aircraft diverted to Shannon as a precaution due to a technical issue. The aircraft is currently being examined.
Other "Aviation Services" reported based on a single unverified tweet without further checks, that the aircraft diverted due to a woman in labour.
