Airworthiness Directives; Bombardier, Inc., Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This AD was prompted by sleeve loops on some passenger oxygen mask lanyards that had improper crimping and unsealed ends. This AD requires an inspection of the passenger oxygen mask lanyards and replacement of defective oxygen mask lanyards. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.

604 Variant; applies to serial numbers identified in Bombardier Service Bulletin 605-35-008, dated October 28, 2022

Whether AD 2023-24-05 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2023-24-05 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
