Is AD 2020-03-17 a recurring Airworthiness Directive?

Yes — AD 2020-03-17 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Airworthiness Directives; Bombardier, Inc., Airplanes

What this AD requires

The FAA superseding Airworthiness Directive (AD) 2015-24-04, which applied to certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2015-24-04 required repetitive inspections of the cage assembly for damaged or detached window louver panel assemblies (WLPAs) and blowout panels (BOPs), and corrective actions if necessary. This AD requires one-time inspections of the WLPAs and BOPs, corrective actions if necessary, and a revision of the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations, which would terminate the inspection requirement. This AD was prompted by a determination that new airworthiness limitations, as well as additional actions, are necessary to address the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. 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–?, 10002–?, 15001–?, 19001–?.

Applies only to airplanes with a Class C cargo compartment configuration. Serial number ranges are per model: CL-600-2B19 (Regional Jet 100 & 440) serial numbers 7003 and subsequent; CL-600-2C10 (Regional Jet 700/701/702) serial numbers 10002 and subsequent; CL-600-2D15 (Regional Jet 705) and CL-600-2D24 (Regional Jet 900) serial numbers 15001 and subsequent; CL-600-2E25 (Regional Jet 1000) serial numbers 19001 and subsequent.

Whether AD 2020-03-17 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 2020-03-17 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.
