Airworthiness Directives; Airbus Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, and A320 series airplanes and Model A321-111, -112, -131, -211, -212, -213, -231, -232 airplanes. This AD requires revising the airplane flight manual (AFM) to provide guidance to the flight crew for emergency procedures when erroneous airspeed indications are displayed on the back-up speed scale (BUSS). This AD was prompted by a determination that, when two angle of attack (AoA) sensors are adversely affected by icing conditions at the same time, data displayed on the BUSS could be erroneous. We are issuing this AD to address the unsafe condition on these products.

Applies only to airplanes with Airbus modification 35871 embodied in production or Service Bulletin A320-34-1397 embodied in service, except airplanes on which modification 159281 has also been embodied in production or Service Bulletin A320-34-1658 or A320-34-1659 has also been embodied in service.

Whether AD 2018-02-18 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 2018-02-18 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.
