QUESTIONS

Challenger 300 AD questions

Source: FAA final rules under 14 CFR part 39, from the Federal Register. The FAA’s Dynamic Regulatory System holds the official list.

How many airworthiness directives apply to the Challenger 300?

57 FAA ADs published since 1995 name the Bombardier Challenger 300's type certificate model (BD-100-1A10) in their applicability. 51 are still in effect as far as the Federal Register shows; the others were superseded by a later AD or removed. How many apply to one aircraft depends on its serial number, equipment and modifications.

Which Challenger 300 ADs are recurring?

5 of the ADs in effect require actions that repeat, such as inspections at set intervals, until a terminating action is done. They are marked Recurring above. One-time ADs are complied with once, but the compliance record stays with the aircraft.

What is the latest Challenger 300 airworthiness directive?

AD 2026-02-06, effective Feb 25, 2026: Bombardier, Inc., Airplanes. The list is refreshed from the Federal Register every weekday.

How do I know whether an AD applies to my Challenger 300?

Read the AD's applicability paragraph, shown with each AD on this page, against the aircraft's serial number and its installed engines, propellers, parts and modifications. A certificated mechanic or inspector makes the determination and records the method of compliance in the maintenance records. The FAA's Dynamic Regulatory System holds the official list of ADs.

Why are engine and propeller ADs missing?

This page lists ADs whose applicability names the Bombardier Challenger 300 airframe, plus appliance ADs that list it among the aircraft they can be installed on. Engine and propeller ADs name the engine or propeller model rather than the aircraft, so check them by the installed engine and propeller models.
