A Lufthansa Boeing 747-8, registration D-ABYK performing flight LH-403 from Newark,NJ (USA) to Frankfurt/Main (Germany) with 326 people on board, was enroute at FL330 about 190nm eastnortheast of Boston,MA (USA) when the flight crew donned their oxygen masks and decided to divert to Boston reporting smoke in the cockpit. The aircraft turned around, descended to FL320 initially and landed safely on Boston’s runway 33L about 40 minutes later.

Massachusetts Police reported the flight was carrying 326 people, the crew reported smoke in the cockpit and was wearing their oxygen masks while diverting to Boston. The aircraft landed without further incident.

The airline reported a defective coffeemaker in the first class galley caused the diversion. The origin of the odour could not be identified in flight prompting the diversion to Boston. Mechanics subsequently identified the coffeemaker as source.
