Airworthiness Directives; Airbus Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -300, and -200 Freighter series airplanes; and all Airbus Model A340-200 and -300 series airplanes. This AD was prompted by a determination that the bonding lead from a certain isolation valve to a frame was too close to an electrical harness, which might cause chafing between the electrical harness and the associated bonding lead. This chafing could lead to a short circuit of the isolation valve and consequent non-closure of the isolation valve, which would prevent the air flow to be shut off in case of fire. This AD requires modifying the bonding lead installation of the isolation valve. We are issuing this AD to prevent such chafing, which could result in non-closure of the isolation valve in the event of a fire and consequent damage to the airplane and injury to its occupants.

ModelsA330-201, A330-202, A330-203, A330-223, A330-243, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, A330-341, A330-342, A330-343, A330-223F, A330-243F, A340-211, A340-212, A340-213, A340-311, A340-312, A340-313, A330, A340

Applies to all manufacturer serial numbers of the listed A330 passenger models except those with Airbus modification 201500 embodied in production, and all manufacturer serial numbers of the listed A330 freighter models (A330-223F, A330-243F) except those with Airbus modification 201681 embodied in production. All A340 models listed apply to all manufacturer serial numbers with no exception.

Whether AD 2013-05-09 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 2013-05-09 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.
