Airbus (AIR.PA) confronts”industrial shocks” if it fails to resolve a dispute which has driven a wedge between the European planemaker and significant client Qatar Airways, the airline’s chief executive told Reuters on Thursday.

Raising the stakes of a dare possibly affecting plane deliveries, which eventually became people, Chief Executive Akbar Al Baker advocated the Airbus board to intervene right.

“(Airbus) have to find real and they will need to understand this problem will produce industrial consequences to them,” Al Baker told Reuters in an interview.

“The ball is in their court to fix the issue we have together, and it is up to them to solve this as soon as possible before things could Find a little out of hand,” Al Baker additional

“I believe today is a time to get the Airbus board to become involved and consider exactly what is happening,” Al Baker said.

An Airbus spokesman stated the planemaker frequently held discussions with its clients and these stayed confidential.

Al Baker was talking on the sidelines of the St Petersburg International Economic Forum, chaired by President Vladimir Putin, in which a sizable Qatari delegation is current this season.

The Gulf airline officer is one of the most outspoken and influential in the aviation sector and has occasionally lashed out in Airbus or Boeing (BA.N) for flaws or quality lapses.

The airline says its own exacting criteria signify its superior brand, although aerospace executives have accused of yanking these facts before to postpone carrying deliveries or gain leverage in different discussions, a proposal it’s denied.
