Airworthiness Directives; Airbus Model A330-300, A340-200, and A340-300 Series Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

ModelsA330-301, A330-302, A330-303, A330-321, A330-322, A330-323, A330-341, A330-342, A330-343, A340-211, A340-212, A340-213, A340-311, A340-312, A340-313, A330, A340
Serial-conditional — narrows to serials ?–588, ?–598.

First serial range (up to and including MSN 588) applies to the A330-301/-302/-303/-321/-322/-323/-341/-342/-343 airplanes, except those on which Airbus Service Bulletin A330-27-3110 has been embodied; second serial range (up to and including MSN 598) applies to the A340-211/-212/-213/-311/-312/-313 airplanes, except those on which Airbus Service Bulletin A340-27-4115 has been embodied.

Whether AD 2009-18-20 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 2009-18-20 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.
