Older Bombardier jets must now meet new safety checks, closing a loophole

US aviation regulators are expanding a mandatory safety inspection rule to include more older Bombardier Challenger jets. This means a specific group of aircraft that previously avoided these checks will now have to undergo them.

Aviation safety rules are often updated as new information comes to light, but sometimes specific aircraft models or serial numbers are missed in the initial rollout. This proposed rule closes one such gap, ensuring that all relevant aircraft are subject to the same safety standards. It means that owners and operators of these specific jets will face new maintenance requirements, potentially increasing their operational costs.
