Is AD 2015-17-04 a recurring Airworthiness Directive?

No — AD 2015-17-04 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2015-17-04 apply to?

AD 2015-17-04 applies to Bombardier — models CL-600-2C10, CL-600-2D15, CL-600-2D24, CL-600. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by reports of a disconnect between the elevator lever and control rod. This AD requires replacement of left and right fixed control rods and lever assemblies of the elevator control system. We are issuing this AD to prevent a disconnect between the elevator lever and control rod, which could lead to un-commanded elevator movement of the associated control surface, a large difference between the position of the left and the right elevator control surfaces, and consequent reduced controllability of the airplane and degradation of the structural integrity of the horizontal stabilizer.

Serial-conditional — narrows to serials 10002–10337, 15001–15298.

CL-600-2C10 = Regional Jet Series 700/701/702; CL-600-2D15 = Regional Jet Series 705; CL-600-2D24 = Regional Jet Series 900.

Whether AD 2015-17-04 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 2015-17-04 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.
