Qatar Airways says it has grounded 13 Airbus A350s over degradation of the plane's fuselage.
Qatar Airways made the announcement on Thursday, further escalating a monthslong dispute with the European airplane maker.
It says the aircraft will be removed from service until such time as the root cause can be established and a satisfactory solution made available to permanently correct the underlying condition.
Airbus did not immediately respond to a request for comment.
Qatar Airways, based in the energy-rich Arabian Peninsula nation of the same name, is a major East-West long-haul carrier. It is one of the biggest buyers of the twin-aisle aircraft.
