Alright, this is what I can make out so far about the Bombardier / Gulfstream jet thing:
The Bombardier Global 8000 just got certified in November by Transport Canada. In accordance w/ an agreement between the FAA, Transport Canada, European union Aviation Safety Agency (EASA) & Brazil’s safety authority (ANAC) to honor each other’s Technical Standard Order (TSO) certifications, the other agencies each followed suit within 2 months. So, the Canadian-made Global has its certification in each of these markets.
The Gulfstream G700/800 was issued a “temporary certification” by the FAA in 2024. It was temporary because during design & initial production, the FAA introduced a new standard for testing the fuel system icing prevention which hadn’t existed before. Previous approval was done via analysis, but for this approval the FAA decided it would need full flight testing. Gulfstream would have to devise a process, get it approved & then build a rig, which was estimated to take two years. Gulfstream asked for 3 just in case, arguing the G700/800 fuel system was not radically different than the G550 & that this was a surprise requirement.
If the FAA didn’t agree, the jet was in limbo. Not sure how Gulfstream would handle it. Idle the line & lay off employees? I don’t know. But, the FAA agreed in March 2024. The EASA followed in May. Brazil in 2025.
These deals to honor each other’s TSO certifications are “Reciprocal Acceptance”. They streamline getting certification in each market, which is extremely time consuming & expensive.
Canada is the only partner that did not honor the reciprocal agreement. Maybe they will eventually, but they are very late to the party.
As I mentioned, the technical issue is preventing ice from forming in the fuel tanks. It’s cold at altitude. Jets use fuel additives to help prevent icing, and some even heat the fuel. It’s a common trick.
Both Bombardier & Gulfstream heat the fuel pretty similarly. Some of the fuel bound for the engine gets diverted (intentionally) & flows over the outside of the oil system. That cools the oil & warms the fuel in a “heat exchange”. The now warm fuel gets pumped back into the fuel tank. It’s not a massive amount, but it’s enough to keep the fuel from freezing (which it wouldn’t do in most situations even if this system didn’t exist, but might in some). There are minor differences, but it’s not a major thing & Gulfstream has never had an issue with it.
Anyway, when it comes to big, class-leading business jets, the two big hitters are Bombardier & Gulfstream. Plenty of others make business jets, but not like these. It’s like Ferrari & Lamborghini. These are the top of the line, serious machines.
So, it seems like the question is why hasn’t Canada honored the reciprocal agreement when the U.S. & other partners do, at least from what I can tell. Gulfstream can’t deliver jets to the Canadian market until they do, while Bombardier can deliver to the U.S.
I suspect this looks like Canada protecting its markets to some.
And that, friends, is my book report.
