Is AD 2018-09-16 a recurring Airworthiness Directive?

No — AD 2018-09-16 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2018-09-16 apply to?

AD 2018-09-16 applies to Airbus — models A319-111, A319-112, A319-113, A319-114, A319-115, A319-131, A319-132, A319-133. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are superseding Airworthiness Directive (AD) 2015-15-13, which applied to certain Airbus Model A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2015- 15-13 required a modification of the potable water service panel and waste water service panel, including doing applicable related investigative and corrective actions. This AD requires a modification of the waste water and potable water service panels with new compliance times. This AD also removes certain airplanes from the applicability and adds Model A320-216 airplanes to the applicability. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the potable water and waste water service panel areas are subject to widespread fatigue damage (WFD). We are issuing this AD to address the unsafe condition on these products.

Excludes airplanes on which Airbus modification 160055 or modification 160056 has been embodied in production, and excludes Model A319 series airplanes ("Corporate Jet") on which modification 28162, 28238, and 28342 have been embodied.

Whether AD 2018-09-16 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 2018-09-16 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.
