Airworthiness Directive · Amendment 39-16822 · Hydraulic power
Airbus Airplanes
This AD applies to the products identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes.
(2) Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes.
(3) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; A300 B4-605R and B4-622R airplanes; A300 F4-605R and F4-622R airplanes; and A300 C4-605R Variant F airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A310 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4- 605R Variant F airplanes (collectively called A300-600 series airplanes). This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * * * A recent analysis conducted by the manufacturer showed a particular risk for explosive failure of the * * * hydraulic accumulator. This condition, if not detected and corrected, might, for some aeroplane installations, lead to damage to all three hydraulic circuits, possibly resulting in loss of control of the aeroplane or could, for certain other aeroplane installations, lead to an undetected fire in the wheel bay. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 30 months or 6,000 flight hours after the effective date of this AD, whichever occurs first: Do a detailed inspection of each type 5 hydraulic accumulator, part number (P/N) 3059103-1, P/N 3059103-2, P/N 3059103-8, and P/N 3059103-9, to determine if an old design accumulator (i.e., pre-1984) is installed on any affected hydraulic circuit indicated in table 1 of this AD, as applicable, in accordance with the Accomplishment Instructions of the applicable Airbus mandatory service bulletin identified in table 2 of this AD.

(h) If, during any detailed inspection required by paragraph (g) of this AD, an old design hydraulic accumulator (i.e., pre-1984) is found installed on any affected hydraulic circuit as indicated in table 1 of this AD, as applicable to airplane model, before further flight replace each affected old design accumulator with a new design accumulator, in accordance with the Accomplishment Instructions of the applicable Airbus mandatory service bulletin identified in table 2 of this AD.
(i) Before further flight after accomplishing the inspection required by paragraph (g) of this AD: Install a placard at the designated location of any affected hydraulic circuit indicated in table 1 of this AD, as applicable to airplane model, in accordance with the Accomplishment Instructions of the applicable Airbus mandatory service bulletin identified in table 3 of this AD.
