A KLM Boeing 777-300, registration PH-BVF performing flight KL-791 from Amsterdam (Netherlands) to Sao Paulo Guarulhos,SP (Brazil), was enroute at FL320 about 120nm south of Shannon (Ireland) when the crew decided to return to Amsterdam due to the #1 engine (GE90) using more oil than permitted. The aircraft dumped fuel on the way back and landed safely back in Amsterdam about 70 minutes later.

A replacement Boeing 777-300 registration PH-BVK is estimated to reach Sao Paulo with a delay of 4.5 hours.

A passenger tweeted the aircraft returned to Amsterdam due to an electrical failure.
