Airworthiness Directives; Airbus Model A319, A320, A321, A300, A310, A300-600, A330, and A340 Series Airplanes

What this AD requires

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T98-15-51 that was sent previously to all known U.S. owners and operators of all Airbus Model A319, A320, A321, A300, A310, A300-600, A330, and A340 series airplanes by individual telegrams. This AD requires an initial and repetitive in- flight operational checks of the alternate braking system, and replacement of the braking dual distribution valve (BDDV) with a serviceable part, if necessary. This action is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the alternate braking system, which could result in the airplane overrunning the end of the runway during landing.

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.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 98-20224 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 98-20224 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.
