Is AD 2012-25-02 a recurring Airworthiness Directive?

Yes — AD 2012-25-02 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2012-25-02 apply to?

AD 2012-25-02 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 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 airworthiness limitations section (AWL) of the Instructions for Continued Airworthiness (ICA) of the Canadair Regional Jet Maintenance Requirements Manual (MRM) by incorporating new procedures for repetitive detailed and special detailed inspections for cracking of the aft pressure bulkhead. This new AD requires revising the maintenance program to incorporate a revised task specified in a certain temporary revision, which requires an improved non-destructive inspection procedure; and adds airplanes to the applicability. This AD was prompted by multiple reports of cracks on the forward face of the rear pressure bulkhead (RPB) web. We are issuing this AD to detect and correct cracking in the RPB, which could result in reduced structural integrity and rapid decompression of the airplane.

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–?.

Serial numbers 7003 and subsequent (Regional Jet Series 100 & 440). Also requires revisions to operator maintenance documents (compliance required by 14 CFR 91.403(c)).

Whether AD 2012-25-02 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 2012-25-02 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.
