PARIS (AP) -- Airbus has advised airlines to test noisy doors on the world's largest passenger airliner, the A380, after identifying a problem with the door seal that could lead to a fall in the cabin pressure.
The company said Wednesday that it's assessed noisy doors on some aircraft, following an air leak on a Singapore Airlines flight in January that caused the cabin pressure to drop, and found 10 percent of those tested needed reinforcing.
Airbus spokesman Justin Dubon said the company had "identified and understood the root cause" of the door issue and that they were related to the door seal.
Dubon said Airbus would fix problems found by airlines.
The door, he insisted, "can't open midflight."
