Trump Demands Bombardier Build Aircraft in US or Face Market Ban, Escalating US-Canada Aviation Dispute

President Donald Trump said on September 7 that Bombardier should no longer be allowed to sell aircraft in the United States unless it manufactures them there, escalating an ongoing trade dispute between Washington and Ottawa. The White House has not explained how such a restriction would be implemented, nor whether it would take the form of tariffs, import restrictions, certification action, or another mechanism.

The ultimatum follows an earlier confrontation that began in January, when Trump accused Canada of unfairly delaying certification of four Gulfstream business jets — the G500, G600, G700, and G800 — all of which had FAA approval but still required Canadian validation. Trump threatened to decertify Canadian-built Bombardier aircraft in the US and impose a 50% tariff on Canadian aircraft unless the situation was resolved. Transport Canada approved the G500 and G600 on February 15 and the G700 and G800 later that month.

Bombardier employs more than 3,000 people across nine US facilities and works with approximately 2,800 American suppliers. The Global 8000's wings are manufactured at Bombardier's Red Oak, Texas facility, while its GE Aerospace Passport engines are assembled in Lafayette, Indiana. The Challenger 3500 uses Honeywell's HTF7000-family engine, produced in Phoenix, Arizona. Final assembly remains in Canada — in Montreal for the Challenger family and in Toronto for the Global family. Bombardier's current lineup includes the Challenger 3500 (3,400 nm), Challenger 650 (4,000 nm), Global 5500 (5,900 nm), Global 6500 (6,600 nm), Global 7500 (7,700 nm), and Global 8000 (8,000 nm). The company exited its commercial aircraft businesses when the CSeries became the Airbus A220 and Mitsubishi Heavy Industries acquired the CRJ program and its type certificates in 2020.

NetJets holds a firm order for 12 Challenger 3500s with options for 232 more — a potential total of 244 aircraft worth more than $6 billion if all options are exercised, according to figures Bombardier disclosed in 2024. Flexjet describes itself as the longest-standing fractional operator of the Challenger family and has 86 Bombardier Challenger 300/350/3500-series aircraft on its US operating certificate. Kansas City-based Airshare has commitments covering up to 40 Challenger 3500s across two agreements.

This dispute shows how a bilateral certification fight over four Gulfstream models has widened into a threat against an entire foreign manufacturer's US market access, with the mechanism still undefined months after the first ultimatum. Fractional programs are especially exposed because they concentrate deliveries: NetJets' order alone covers up to 244 Challenger 3500s, and Flexjet's 86-aircraft Challenger fleet sits entirely on aircraft assembled outside the US.

Business-jet manufacturing routinely splits components across borders — wings in Texas, engines in Indiana or Arizona, final assembly in Montreal or Toronto — which is exactly why a blunt US-manufacturing mandate is hard to execute without also disrupting thousands of American supplier jobs tied to the same aircraft. Bombardier cannot relocate final assembly on any near-term timeline, which leaves tariffs, negotiated concessions, or other trade restrictions as the most plausible outcomes rather than an outright sales ban.

Whether the eventual measure targets only new sales, imports generally, or certification specifically will determine how severely NetJets, Flexjet, and Airshare are affected, and none of that scope has been specified yet. The next concrete signal will be whichever mechanism the White House actually announces, since that choice — tariff versus certification action versus negotiated settlement — decides whether existing fleets, pending deliveries, or only future orders are affected.
