‍DALLAS — A U.S. political flare-up over aircraft certification put an unexpected spotlight on how deeply Canadian-built jets and helicopters are embedded in the U.S. fleet, especially Bombardier business aircraft and regional jets that fly thousands of daily segments.

U.S. President Donald Trump used a Truth Social post today to call on the FAA to “decertify” Bombardier private jets, framing the threat as retaliation for Canada’s refusal to certify certain Gulfstream models, according to reporting. The move raised questions about what “decertify” could mean in practice, since aircraft type certification sits with regulators, not politicians, and typically ties to engineering and safety findings rather than trade disputes.

For a sense of scale, Cirium data shared with Airways show 5,425 Canadian-made aircraft (including narrowbodies, regional jets, trainers, and helicopters) in service and registered in the U.S. Of that total, 2,678 are Bombardier aircraft built in Canada operated by 1,202 operators. Cirium’s dataset also flags 150 Bombardier Global Express aircraft in the U.S. registry, spread across 115 operators, underscoring how widely those long-range business jets are distributed across corporate and private fleets.

The same Cirium snapshot highlights Canada’s role in U.S. commercial operations beyond business aviation. Canadian-built regional jets remain a core tool for U.S. network connectivity, and outside reporting notes that hundreds of Bombardier CRJ aircraft fly U.S. schedules each day, making any broad certification threat operationally explosive even before it reaches legal reality.

Cirium also counts 58 Airbus A220-family aircraft in U.S. service, operated by Delta Air Lines (46), JetBlue (10), and Breeze (2)—a reminder that “Canadian-made” spans multiple OEMs and programs, not just Bombardier. (Airbus builds A220s in both Canada and the U.S.; Cirium’s figures refer to Canadian-made frames in the U.S. registry.)

Why It Matters

Even if the rhetoric never translates into formal action, it shows how quickly geopolitics can collide with fleet realities—and why operators, lessors, and manufacturers treat certification pathways as one of aviation’s most sensitive chokepoints. For background, Gulfstream pursued multi-regulator approvals for its newest large-cabin types, with certification milestones that typically involve the FAA and other authorities.

Note: Bombardier sold the Dash 8 program and the De Havilland brand to Longview in 2019. De Havilland Aircraft of Canada now runs the program.
