it reminds me airbus vs quatar airways that was complaining about the paint on the A350January 2022, the airline said “these defects are not superficial and one of the defects causes the aircraft’s lightning protection system to be exposed and damaged”.
Airbus said the surface degradations were “non-structural” and had “no airworthiness impact on the A350 fleet”.and was threatening to cancel the order.
Seen Airbus playing hard ball with the customer more these days, maybe just because they can. I think these H160 will be sold anyways
