Models named: A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus Model A330-201, -202, -203, -223, -223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342 and -343 airplanes; and Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes; certificated in any category, fitted with a hydraulic reservoir (HR) pressure relief valve (PRV) part number (P/N) 42F0026 installed on TECHSPACE HR having P/N 42F1005, 42F1203, 42F1304, 42F1412, 42F1512, or 42F1607.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within the compliance time defined in table 1 to paragraph (g) of this AD, as applicable, inspect the HR fluid level and nitrogen pressure of each hydraulic circuit, in accordance with the instructions of paragraph 4.2.2.1 of Airbus Alert Operators Transmission (AOT) A29L005-16, Revision 01, dated June 28, 2016. Repeat the inspection thereafter at intervals not to exceed 1,600 flight hours. Table 1 to Paragraph ( g ) of This AD—Initial Inspection Compliance Time     Compliance Time (A or B, whichever occurs later) A Before accumulating 1,600 flight hours since first flight of the airplane. B Within 1,000 flight hours or 3 months, whichever occurs first after the effective date of this AD.

Unsafe condition

This AD was prompted by reports of certain hydraulic reservoirs (HRs) becoming depressurized due to air leakage from the HR PRV. We are issuing this AD to detect and correct air leakage from the HR PRV, which could lead to the loss of one or more hydraulic systems, with the possible result of loss of control of the airplane.

Affected ADs

None.
