Is AD E8-24549 a recurring Airworthiness Directive?

No — AD E8-24549 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD E8-24549 apply to?

AD E8-24549 applies to Bombardier — models CL-600-1A11, CL-600-2A12, CL-600-2B16, CL-600-2B19, CL-600. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A, CL-601-3R, & CL-604 (Including CL-605 Marketing Variant)) Airplanes, and Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) that applies to all Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes and Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes. The existing AD currently requires revising the airplane flight manuals (AFMs) to include new cold weather operations limitations and procedures. This AD requires revising the AFMs to include a requirement for flightcrew training regarding enhanced take-off procedures and winter operations. This AD results from reports of uncommanded roll during take-off. We are issuing this AD to prevent possible loss of control on take-off resulting from even small amounts of frost, ice, snow, or slush on the wing leading edges or forward upper wing surfaces.

Whether AD E8-24549 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 E8-24549 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.
