AD 2014-15-09 Airworthiness Directives; Airbus Airplanes
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; Model A340-211, -212, -213, -311, -312, and -313 airplanes; and Model A340-541 and -642 airplanes; certificated in any category; all manufacturer serial numbers.
Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Required actions
(1) At the time specified in paragraph (g)(2) of this AD: Accomplish an operational test of the hydraulic locking function on each SSC (any type), when fitted on the Blue or Yellow hydraulic circuits, in accordance with the Accomplishment Instructions of the applicable service information identified in paragraph (g)(1)(i), (g)(1)(ii), or (g)(1)(iii) of this AD. Repeat the operational test thereafter at intervals not to exceed 48 months. (i) Airbus Service Bulletin A330-27-3195, Revision 01, dated February 6, 2014 (for Model A330-200 Freighter, A330-200 and -300 series airplanes). (ii) Airbus Service Bulletin A340-27-4188, Revision 01, dated February 6, 2014 (for Model A340-200, and -300 series airplanes). (iii) Airbus Service Bulletin A340-27-5059, Revision 01, dated February 6, 2014 (for Model A340-500 and -600 series airplanes). (2) At the latest of the times specified in paragraphs (g)(2)(i), (g)(2)(ii), and (g)(2)(iii) of this AD, do the operational test specified in paragraph (g)(1) of this AD. (i) Within 48 months since first flight of the airplane. (ii) Within 48 months since accomplishing the most recent operational test, as specified in the applicable Airbus All Operators Telex (AOT) A330-27A3185; or AOT A340-27A4181; both dated January 4, 2012. These AOTs were incorporated by reference in AD 2012-25-10, Amendment 39-17291 (77 FR 76228, December 27, 2012). (iii) Within 24 months after the effective date of this AD.
Unsafe condition
This AD was prompted by reassessment of an unsafe condition related to MZ-type spoiler servo-controls (SSCs) that did not remain locked in the retracted position (hydraulic locking function) after manual depressurization of the corresponding hydraulic circuit. This reassessment resulted in the determination that performing repetitive operational tests of all SSC types is necessary. We are issuing this AD to detect and correct loss of the hydraulic locking function during take-off, which, in combination with one inoperative engine, could result in reduced controllability 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.
