Older Bombardier jets need new maintenance rules to stay in the air

The US aviation regulator is requiring new or stricter maintenance rules for certain older Bombardier Challenger business jets. This means operators of these planes must update their maintenance programs to incorporate these new safety limits.

Aircraft maintenance rules are not static. As planes age, or as new safety data emerges, regulators update the requirements. This ensures that older aircraft continue to meet current safety standards, even if their original design specifications are decades old. It means that the cost of operating these specific jets will increase, as owners must invest more in inspections and parts.
