Is AD 2013-20-04 a recurring Airworthiness Directive?

No — AD 2013-20-04 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2013-20-04 apply to?

AD 2013-20-04 applies to Airbus — models A318-111, A318-112, A318-121, A318-122, A319-111, A319-112, A319-113, A319-114. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a determination that certain special washers used in the bearing installation of the retraction jack anchorage fitting in the main landing gear (MLG) were incorrectly manufactured. This AD requires an inspection of the left-hand (LH) and right-hand (RH) bearing assemblies of the MLG retraction jack anchorage fitting to verify that the special washer is seated correctly, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct installation of incorrectly manufactured special washers, which could lead to a local stress concentration resulting in possible reduction of the fatigue life of the jack fitting, and consequent reduction of the structural integrity of the affected MLG.

Whether AD 2013-20-04 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.

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.
