Airworthiness Directives; Airbus Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-202, -203, -223, and -243 airplanes. This AD requires contacting the FAA to obtain instructions for addressing the unsafe condition on these products, and doing the actions specified in those instructions. This AD was prompted by a design review of the airplane configuration incorporating certain fire extinguisher bottles and an optional galley cooling rack installation, which revealed that the air cooling rack is installed too close to the supply hose of a high rate fire extinguishing bottle. We are issuing this AD to address the unsafe condition on these products.

Which aircraft AD 2018-03-21 applies to

MakesAirbus
ModelsA330-202, A330-203, A330-223, A330-243, A330

Applies only to airplanes incorporating Airbus modification 45785, 45883, or 46616; excludes airplanes with modification 200195, modification 40487 (production installation of Pacific-Scientific fire extinguisher bottles), or Service Bulletin A330-26-3013 (in-service installation of Pacific-Scientific fire extinguisher bottles).

Whether AD 2018-03-21 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 2018-03-21 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.
