This should be a good incentive for European aircraft manufacturers to develop European-made components of all types, so that an Airbus has nothing American in it. This is already in progress, for example receivers for US GPS will soon be unnecessary; Galileo will soon be available world-wide for all European users. Engines are a bit of a problem, most narrowbody jet aircraft are partly or wholly made by Americans (for example IAE and CFM both have American partners involved) - but Rolls-Royce could make narrowbody engines again if they wished, and Safran probably too. The Russians could also supply, too.
Trump's attitude to China is already driving them to develop indigenous high technology industries to make things they currently buy in from the USA because the USA is clearly an unreliable partner. Europe will likely do the same.
The real problem is US "Secondary sanctions". "Primary sanctions" means a US company can't trade with Iran - so Boeing can't sell to an Iranian airline. "Secondary sanctions" mean a US company can't trade with any company that trades with Iran. So American Airlines can't buy an Airbus if Airbus also sells to Iran (even if the Airbus aircraft contains no American parts). Secondary sanctions are the world-wide bullying tactic of the USA, and they have been stopped before - the EU forced the USA to withdraw secondary sanctions over Cuba in 1996. See
