Models named: A318-111, -112, -121, -122, A319-111, -113, -114, -115, -131, -132. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to the Airbus airplanes, certificated in any category, identified in paragraphs (c)(1) through (c)(4) of this AD, all manufacturer serial numbers. (1) Airbus Model A318-111, -112, -121, and -122 airplanes. (2) Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes. (3) Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes. (4) Airbus Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For airplanes equipped with SEC hardware C part number (P/N) B372CAM0100 with software standard 122 (P/N B372CAM0101), 124 (P/N B372CAM0102), or 125 (P/N B372CAM0103), on SEC position 1 or 2, or both: Within 30 days after the effective date of this AD, revise the After Start Normal Procedures section of the AFM to include the statement specified in figure 1 to paragraph (g) of this AD. This may be done by inserting a copy of this AD, or Airbus A318/A319/A320/A321 Temporary Revision TR572, Issue 1.0, dated August 13, 2015, to the Airbus A318/A319/A320/A321 Airplane Flight Manual, into the applicable AFM. Figure 1 to Paragraph ( g ) of This AD—AFM Temporary Revision AFTER START NORMAL PROCEDURE After both engines start: Turn OFF then ON SEC 1 and SEC 2 one after another. Note 1 to paragraph (g) of this AD: When a statement identical to that in figure 1 to paragraph (g) of this AD has been included in the After Start Normal Procedures section of the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD or Airbus A318/A319/A320/A321 Temporary Revision TR572, Issue 1.0, dated August 13, 2015, may be removed from the AFM. Note 2 to paragraph (g) of this AD: Airbus Operations Engineering Bulletin OEB-50 provides additional information on the subject addressed by this AD.
Unsafe condition
This AD was prompted by reports of spoiler and elevator computer (SEC) latent failures; an undetected loss of a SEC in flight will result in loss in redundancy for elevator control. This AD requires revising the After Start Normal Procedures section of the airplane fight manual (AFM) to provide procedures that will address this loss of redundancy. We are issuing this AD to ensure that the flightcrew has procedures to address loss of redundancy of SEC 1 and SEC 2. A SEC failure, in conjunction with a loss of trimmable horizontal stabilizer (THS) electrical control due to jamming or rupture, could result in failure of an elevator and aileron computer, and consequent loss of elevator control and 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.
