Is AD 2014-17-04 a recurring Airworthiness Directive?

Yes — AD 2014-17-04 requires a repetitive inspection every 6600 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2014-17-04 apply to?

AD 2014-17-04 applies to Bombardier, Inc. — models CL-600-2B19, CL-600. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Bombardier, Inc. Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by reports that elevator power control unit (PCU) shear pins may fail prematurely. This AD requires repetitive replacement of the elevator PCU shear pins. We are issuing this AD to prevent premature elevator PCU shear pin failure. If all pins fail on one elevator, the elevator surface would become inoperative, which could reduce the controllability of the airplane and could result in a loss of redundancy for flutter prevention.

Repetitive inspection. Re-inspect every 6600 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Serial-conditional — narrows to serials 7003–?.

Regional Jet Series 100 & 440; serial numbers 7003 and subsequent.

Whether AD 2014-17-04 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 2014-17-04 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.
