Qatar Airways is reportedly pursuing more than $600m in compensation from Airbus over a fleet of aircraft which it claims is flawed.
The Middle East Airline is seeking the money over surface flaws on A350 jetliners, according to a court document, said Reuters.
In December, Air Cargo News reported Qatar Airways had issued legal proceedings against Airbus in the Technology and Construction Court of London’s High Court of Justice.
Qatar Airways said its national regulator has ordered it to stop flying 21 out of its 53 A350 jets and as a result it is calling for $618m from Airbus over the partial grounding, plus $4m for each day the 21 jets remain out of service.
The surface flaws include including blistered paint, cracked window frames or riveted areas and erosion of a layer of lightning protection, according to Qatar Airways.
However, while Airbus has acknowledged technical problems, it said the jetliners are not unsafe.
