This AD applies to the Airbus SAS airplanes identified in paragraphs (c)(1) through (c)(6) of this AD, certificated in any category, all manufacturer serial numbers.

(2) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
(3) Model A300 B4-605R and B4-622R airplanes.
(4) Model A300 F4-605R and F4-622R airplanes.

(6) Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This AD was prompted by a report of yellow hydraulic system failure, including both braking accumulators, due to failure of the parking brake operated valve (PBOV). This AD requires replacement of a certain PBOV with a different PBOV. We are issuing this AD to address the unsafe condition on these products.
Within 60 months after the effective date of this AD, replace the PBOV having part number (P/N) A25315-1 with a PBOV having P/N A25315020-2, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-32-0467, dated July 4, 2017; Airbus Service Bulletin A300-32-6117, dated July 4, 2017; or Airbus Service Bulletin A310-32-2151, dated July 4, 2017; as applicable.
(1) After modification of an airplane as required by paragraph (g) of this AD, do not install any PBOV having P/N A25315-1 on that airplane.
(2) For an airplane that, as of the effective date of this AD, has a PBOV having P/N A25315020-2 installed: As of the effective date of this AD, do not install any PBOV having P/N A25315-1 on that airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
