A Lufthansa Boeing 747-8, registration D-ABYP performing flight LH-506 from Frankfurt/Main (Germany) to Sao Paulo Guarulhos,SP (Brazil), was enroute at FL310 about 90nm southwest of Nantes (France) over the Gulf of Biscaya when the crew decided to return to Frankfurt due to a burning odour, that initially was noticed in the cockpit and spread into the cabin. The cabin was powered down. The aircraft descended to FL260 and landed safely back on Frankfurt’s runway 07R about 90 minutes after the decision to turn around.

The aircraft remained on the ground for about 20 hours, then departed again for flight LH-506 of the next day.

According to information The Aviation Herald received one of the electric fans seized.
