AD 2025-20-13 Airworthiness Directives; Airbus SAS Airplanes
Models named: A330-201, -202, -203, -223, -243, A330-223F, -243F, A330-301, -302, -303. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Airbus SAS airplanes specified in paragraphs (c)(1) through (7), certificated in any category. (1) Model A330-201, -202, -203, -223, and -243 airplanes. (2) Model A330-223F and -243F airplanes. (3) Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes. (4) Model A340-211, -212, and -213 airplanes. (5) Model A340-311, -312, and -313 airplanes. (6) Model A340-541 airplanes. (7) Model A340-642 airplanes.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2025-0175, dated August 8, 2025 (EASA AD 2025-0175).
Unsafe condition
This AD was prompted by the determination that, during flight with landing gear down, the brake system accumulators, and the shut-off valve (SOV) protecting the brake accumulators from internal hydraulic pressure loss, might be exposed to a temperature lower than the one for which the accumulator and SOV are qualified. The FAA is issuing this AD to address damage to the brake accumulator bladder and loss of SOV function, possibly resulting in the loss of emergency braking and consequent damage to the airplane. This AD is also prompted by the determination that, if an airplane is dispatched under existing conditions associated with the “L/G Retraction Fault” alert, operations for Constant Speed Motor/Generator (CSM/G) will be prevented. This condition, if not corrected, would, after a total engine flame out, lead to total loss of electrical power and consequent loss of control of the airplane.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
