Applicability*9
This AD applies to the airplanes identified in paragraphs (c)(1) through (c)(7) of this AD, certificated in any category, manufacturer serial numbers 1 through 1711 inclusive. (1) Airbus Model A330-223F and -243F airplanes. (2) Airbus Model A330-201, -202, -203, -223, and -243 airplanes. (3) Airbus Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes. (4) Airbus Model A340-211, -212, -213 airplanes. (5) Airbus Model A340-311, -312, and -313 airplanes.

Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 42 months after the effective date of this AD, do a trim tank overflow functional test in accordance with the Accomplishment Instructions of the service information specified in paragraphs (g)(1) through (g)(3), as applicable. (1) Airbus Service Bulletin A330-28-3130, Revision 00, dated May 18, 2017. (2) Airbus Service Bulletin A340-28-4140, Revision 00, dated May 18, 2017. (3) Airbus Service Bulletin A340-28-5061, Revision 00, dated May 18, 2017.
Unsafe condition
This AD was prompted by a determination that a functional test to ensure that there is no blockage of vent pipes was not done on the trim tank of certain airplanes during production. We are issuing this AD to address blocked vent pipes, which, in combination with a high level sensor failure, could lead to over-pressurization of the trim tank during refueling or aft fuel transfer. This condition could lead to trim tank rupture and consequent reduced 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.
