What this AD requires

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Four groups: (1) CL-600-2A12 (CL-601) airplanes, S/N 3001-3066, on which Bombardier Service Bulletin 601-0590 has been accomplished; (2) CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes, S/N 5001-5194, on which Bombardier Service Bulletin 601-0590 has been accomplished; (3) CL-600-2B16 (CL-604 Variants) airplanes, S/N 5301-5665; (4) CL-600-2B16 (CL-604 Variants) airplanes, S/N 5701 and subsequent. AD also requires revisions to operator maintenance documents to add new inspections; compliance required under 14 CFR 91.403(c).

Whether AD 2011-09-09 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 2011-09-09 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.
