A Delta Air Lines flight from London Heathrow Airport to Boston Logan International Airport was forced to make an emergency return on Sunday when fumes filled the cockpit. Flight 59 was carrying 259 passengers and operated by an Airbus A330-900 with registration N411DX, which features the special commemorative ‘Team USA’ external color scheme. It was able to make a safe return to the airport about an hour and a half after taking off.
This is the latest incident of a Delta A330-900 experiencing fumes or smoke in the cabin, with three other similar incidents reported last year on its next-generation A330 fleet. The issue may be related to the auxiliary power unit (APU) of the aircraft. Delta is currently replacing the APUs on its fleet of Airbus A320 family aircraft t
