Is AD 2013-01-01 a recurring Airworthiness Directive?

No — AD 2013-01-01 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2013-01-01 apply to?

AD 2013-01-01 applies to Bombardier — 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 superseding an existing airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That AD currently requires revising the airplane flight manual, deactivating and removing certain hydraulic accumulators, inspecting for cracks on accumulators and screw caps, and replacing certain accumulators. For certain airplanes, this new AD reduces the compliance time for a certain replacement. This AD was prompted by reports of on-ground hydraulic accumulator screw cap/end cap failure. We are issuing this AD to detect and correct hydraulic accumulator screw cap/end cap failure, which could result in the loss of the associated hydraulic system and high-energy impact damage to adjacent systems and structure, and consequent loss of control of the airplane.

Serial-conditional — narrows to serials 7003–?.

Regional Jet Series 100 & 440; serial numbers 7003 and subsequent (open-ended range).

Whether AD 2013-01-01 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 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 2013-01-01 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.
