Hard to get exact numbers, but the list is extensive and includes complex, advanced systems that will take years to reshore to the US.
Fly-by-Wire Systems (France — Thales)
Autopilot & Flight Computers (France — Thales, Sweden — Saab)
Hydraulic Actuators (Germany — Liebherr)
Wing Leading Edges (UK — Spirit AeroSystems Scotland)
Horizontal Stabilizers (Italy — Leonardo)
Turbofan core, nacelles, fuel system, Fan & Fan Case - France (Safran)
High-pressure compressors - Germany (MTU Aero Engines)
Germany (Liebherr): Actuation systems
Turbine components and engine alloys - Japan (IHI Corp)
Gearbox components - Italy(Avio Aero)
Sensors & monitoring systems - United Kingdom(Meggitt)
Engine health monitoring systems - Canada (L3Harris)
Structural components - South Korea (Hanwha Aerospace)
Winglets & Composites (Japan — Mitsubishi, South Korea — KAI)
Seats (Germany — Recaro)
Galleys & Lavatories (France — Safran Cabin)
Overhead Bins (Mexico — C&D Zodiac)
Power Management (Switzerland — ABB)
Circuit Breakers (Ireland — Eaton)
All of the engine related items on the list could be solved easily by using GE engines. The fan is made in France but that could be easily exempted from Tariffs. Exemptions could be made for all items used to make American products. Of course it could ALL be solved by having European countries drop their Tariffs.
Make it ALL here or pay the duty. Tariffs are good.
