It comes as Airbus and one of its biggest customers, Qatar Airways, are embroiled in a legal dispute over the grounding of the larger twin-aisle A350 plane.
In December, Qatar’s national carrier announced it was suing Airbus in London over what it described as the “accelerated surface degradation” of the wide-body A350.
Qatar Airways is also refusing to take any more A350s until the problem is fixed.
The state-owned airline will be relying on the long-haul A350 for the increased inflow of passengers to Qatar for the month-long FIFA 2022 World Cup, which will be played in the Arab Gulf state starting Nov. 21.
Qatar Airways has a fleet of 53 Airbus A350s in both its 1000 and 900 series. The airline has more on order with the France-based aeroplane manufacturer, making its total order of 76 A350s the most of any airline worldwide.
In a brief comment to the AP, Airbus confirmed that it did terminate a contract for 50 A321s ordered by Qatar Airways. The airline did not provide further details.
Qatar Airways did not immediately respond to requests for comment on the A321neo contract.
In a public statement last year, Qatar Airways said it was left with no alternative but to seek a resolution through the courts to ensure that Airbus undertakes a thorough investigation of the degradation beneath the paint on the fuselage of the aircraft.
Airbus has said it intends to vigorously defend its position as no other airline flying the A350 has grounded the aircraft due to safety concerns.
