This AD applies to Airbus Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, B4-203, B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; certificated in any category, all certified models and all serial numbers on which any Crissair check valve part number 2S2794-1 is installed.
We are adopting a new airworthiness directive (AD) for the products listed above. 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:
Unless already done, do the following actions.
(1) At the applicable compliance time specified in Table 1 of this AD: For Crissair check valves, P/N 2S2794-1, identify the serial number using Appendix 1 of the applicable service bulletin identified in Table 2 of this AD, in accordance with the Accomplishment Instructions of the applicable service bulletin identified in Table 2 of this AD. Except as provided by paragraph (f)(2) of this AD, for any valve having a serial number listed in Appendix 1 of the applicable service bulletin identified in Table 2 of this AD, before further flight, install a new or modified check valve in accordance with the applicable service bulletin identified in Table 2 of this AD.
| Affected check valve installation, identified by FIN (Functional Item Number) | Compliance time |
|---|---|
| (i) Airplanes having Hydraulic System with FIN 29/1388, FIN 29/2388 and FIN 29/3388 | Within 4 months after the effective date of this AD. |
| (ii) Cargo Compartment Fire Extinguishing System, equipped with Flow Metering System (A310 and A300-600 airplanes having “post-Airbus modification 06403” only) FIN 26/0203 | Within 4 months after the effective date of this AD. |
| (iii) Airplanes having Hydraulic System with FIN 29/1378, FIN 29/1382 and FIN 29/1394 | Within 30 months after the effective date of this AD. |
| (iv) Hydraulic System (A300 airplanes having configuration 01 “pre-Airbus modification 03079” only) FIN 29/1381 | Within 30 months after the effective date of this AD. |
(2) Check valves P/N 2S2794-1 marked with an “R” have already been modified in accordance with Crissair Service Bulletin 20070407-29-1 and do not need to be replaced. Check valves with P/N 2S2794 are not affected and do not need to be replaced.
(3) As of the effective date of this AD, no person may install any Crissair check valve, P/N 2S2794-1, on any airplane unless it has a serial number other than those listed in Appendix 1 of the applicable service bulletin identified in Table 2 of this AD, or unless check valve P/N 2S2794-1 is marked with an “R.”

Note 1: This AD differs from the MCAI and/or service information as follows: Although the MCAI states not to install the part identified in paragraph (f)(3) of this AD after accomplishing the actions specified in paragraph (f)(1) of this AD, this AD prohibits installation of the part as of the effective date of this AD.
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.
