Applicability*9
This AD applies to all Airbus SAS airplanes, certificated in any category, specified in paragraphs (c)(1) through (5) of this AD. (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.
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 2020-0265, dated December 2, 2020 (EASA AD 2020-0265).
Unsafe condition
This AD was prompted by a report that the auxiliary power unit (APU) aft fuel pump printed circuit board (PCB) varnish had deteriorated; the varnish is one of the layers of protection against development of an ignition source. The FAA is issuing this AD to address PCB varnish deterioration. This condition, if not addressed, could, in case of a spark or flame in the area of the pump PCB, result in a fire or explosion and consequent loss 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.
