Airworthiness Directives; Airbus SAS Airplanes

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2019-14- 09, which applied to all Airbus SAS Model A330-200 Freighter series airplanes. AD 2019-14-09 required repetitive detailed inspections, including functional testing, of the oxygen crew and courier distribution system (OCCDS) and replacement of affected part(s) if necessary. This AD retains the requirements of AD 2019-14-09 and requires replacement of all affected parts with improved serviceable parts, which is terminating action for the repetitive inspections, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies to airplanes as identified in EASA AD 2020-0092, dated April 24, 2020

Whether AD 2020-21-18 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2020-21-18 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.
