Trump Threatens to Decertify Bombardier Jets in Escalating Trade Dispute

In a significant escalation of trade tensions between the United States and Canada, President Donald Trump announced on Thursday that the U.S. intends to “decertify” Bombardier Global Express business jets. According to reporting by Reuters, the President also threatened to impose a 50% import tariff on all Canadian-made aircraft unless Transport Canada immediately certifies a range of jets produced by U.S. rival Gulfstream.

The ultimatum, delivered via the President’s Truth Social platform, explicitly links the continued operation of Canada’s flagship business jets in the U.S. to the regulatory approval of American aircraft in Canada. The President accused Canadian regulators of “wrongfully, illegally, and steadfastly” blocking the entry of Gulfstream aircraft to protect Bombardier, a claim that threatens to disrupt the North American aerospace supply chain.

The Certification Standoff

At the heart of the dispute is the regulatory status of Gulfstream’s latest ultra-long-range business jets. The Trump administration contends that Transport Canada has delayed the validation of type certificates for the Gulfstream G500, G600, G700, and G800 models. These aircraft are direct competitors to Bombardier’s Global 6500, 7500, and 8000 series jets.

According to industry data, the Gulfstream G500 and G600 received Federal Aviation Administration (FAA) certification in 2018 and 2019, respectively, and are in service globally. However, they lack the necessary Canadian validation to be sold to Canadian customers. The administration views this delay not as a standard regulatory process, but as a non-tariff trade barrier designed to shield Bombardier’s domestic market share.

Impact on Business Aviation

The threat to “decertify” the Global Express series is unprecedented in modern aviation. The United States is the world’s largest market for business jets, and a revocation of the type certificate would effectively ground U.S.-registered Global Express aircraft and halt new deliveries. This would likely devastate Bombardier’s revenue, as the Global 7500 and 8000 are the company’s marquee products.

“All Aircraft” and Commercial Fallout

While the dispute originated in the business aviation sector, the President’s threat extends to “any and all aircraft sold into the United States from Canada.” This broad phrasing implicates the commercial aviation sector, specifically the Airbus A220 (formerly the Bombardier CSeries).

The Airbus A220 is assembled in Mirabel, Quebec, as well as Mobile, Alabama. A 50% tariff on Canadian-made airframes or components could have severe consequences for U.S. carriers. Major operators such as Delta Air Lines, JetBlue, and Breeze Airways rely heavily on the A220 for their domestic networks. In previous trade disputes, Delta has warned that tariffs on these aircraft would reduce capacity and increase costs for American travelers.

The Feasibility of Executive Decertification

President Trump’s threat to unilaterally “decertify” an aircraft raises significant legal and technical questions. Aircraft certification is a rigorous technical process governed by the FAA, based strictly on safety data and engineering standards. Historically, decertification, such as the grounding of the Boeing 737 MAX, is reserved for clear safety failures.

We assess that using certification revocation as an economic lever would likely face immediate challenges in U.S. federal court. While the President has broad authority to impose tariffs under Section 232 (national security) or Section 301 (unfair trade practices), ordering the FAA to revoke a safety certificate for political reasons would compromise the agency’s independence and global standing. However, the mere threat may be sufficient to freeze sales and force diplomatic concessions.

Political Context: Trump vs. Carney

This aerospace dispute occurs against a backdrop of deteriorating relations between Washington and Ottawa. Tensions have spiked since Mark Carney assumed the role of Prime Minister of Canada in March 2025. Following a speech by PM Carney at the World Economic Forum in Davos earlier this month, where he declared the “old world order is dead”, President Trump withdrew an invitation for Canada to join a U.S.-led “Board of Peace.”

The President has previously threatened 100% tariffs on Canadian goods regarding trade deals with China. This latest move against the aerospace sector appears to be a continuation of a strategy to apply maximum economic pressure on the Carney administration.

Frequently Asked Questions

What does “decertifying” an aircraft mean?

Decertification means the FAA revokes the “Type Certificate” that allows an aircraft model to fly legally in U.S. airspace. If enacted, U.S. operators would be unable to fly their Bombardier Global Express jets.

Which Gulfstream jets are involved?

The dispute centers on the Gulfstream G500, G600, G700, and G800. The U.S. claims Canada is delaying their certification to protect Bombardier.

Will this affect commercial airline passengers?

Potentially. If the 50% tariff applies to “all aircraft,” it could impact the Airbus A220 fleets flown by Delta, JetBlue, and Breeze, potentially leading to higher fares or schedule disruptions.
