Airworthiness Directives; Airbus Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Airbus Model A319-111, -112, and -132 airplanes; Model A320-111, -211, -212, -214 and -232 airplanes; and Model A321-111, -211, -212, and -231 airplanes. This AD was prompted by reports that corrosion was found on the overwing refueling aperture on the top wing skin, and that for certain airplanes, repairs made using primer coating may prevent proper electrical bonding provision between the overwing refueling cap adaptor and the wing skin. This AD requires performing an electrical bonding test between the gravity fill re-fuel adaptor and the top skin panels on the left-hand and right-hand wings, and if necessary performing a general visual inspection for corrosion of the component interface and adjacent area, and repairing the gravity fuel adaptor if any corrosion is found. We are issuing this AD to detect and correct corrosion and improper bonding, which in combination with a lightning strike in this area, could create a source of ignition in a fuel tank, resulting in a fire or explosion, and consequent loss of the airplane.

Applies only to airplanes having the specific manufacturer serial numbers listed (discrete list, not a contiguous range).

Whether AD 2012-09-07 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 2012-09-07 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.
