Airworthiness Directives; Bombardier Inc. Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Bombardier Inc. Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600- 2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This AD was prompted by a report of uncommanded nose wheel steering upon landing with touchdown on the runway centerline. This AD requires replacing the nosewheel steering rudder pedal potentiometer universal coupling setscrews. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new life limits for the setscrews. The FAA is issuing this AD to address the unsafe condition on these products.

Model CL-600-1A11 marketed as "600"; CL-600-2A12 as "601"; CL-600-2B16 as "601-3A", "601-3R", and "604" variants.

Whether AD 2026-07-01 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2026-07-01 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.
