Airworthiness Directive 01-18434
recurringAirworthiness Directives; Airbus Model A300 B2, A300 B4, A310, A319, A320, A321, A330, and A340 Series Airplanes; and Model A300 B4-600, A300 B4-600R, and A300 F4-600R (Collectively Called A300-600) Series Airplanes
What this AD requires
This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 B2, A300 B4, A310, A319, A320, A321, A330, and A340 series airplanes; and Model A300 B4-600, A300 B4-600R, and A300 F4-600R (collectively called A300-600) series airplanes. That AD currently requires certain repetitive checks, and replacement of the braking dual distribution valve (BDDV) if necessary. This action requires, for certain airplanes, inspecting and/or replacing the BDDV cover. For all other airplanes, this action provides for optional termination of the repetitive checks. This amendment 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.
Which aircraft AD 01-18434 applies to
Whether AD 01-18434 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:
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.
