Airworthiness Directives; Bombardier, Inc. Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2A12 (CL-601) and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by reports of jamming/malfunctioning of the left-hand engine thrust control mechanism. This AD requires modifying the left-hand engine upper core-cowl. We are issuing this AD to prevent jamming/ malfunctioning of the left-hand engine thrust control mechanism, which could lead to loss of control of the airplane.

S/N 3001-3066 apply to Model CL-600-2A12 (CL-601); S/N 5001-5194, 5301-5665, and 5701-5884 apply to Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 variants).

Whether AD 2013-05-06 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 2013-05-06 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.
