AD No

. : 20 15
- 0191

Date: 22 September 2015

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of the European third countries that participate in the activities of EASA under Article 66 of that Regulation.
This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordan ce with EU 1321/2014 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may ope rate an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency [EU 1321/2014 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exempt ion].

Reason: With the introduction of new Spoiler and Elevator Computer (SEC ) h ardware C Part Number (P/N) B372CAM0100 with software standards 122, 124 and 125 ( identified by P/N B372CAM0101 , P/N B372CAM0102 and P/N B372CAM0103 , respectively ), some airlines have reported receiving maintenance messages , e.g. “SEC OR WIRING FROM L or R ELEV POS MON XDCR ” and/or “ SEC OR WIRING FROM G or Y ELEV POS XDCR ”, which are associated with servo control or elevator transducer monito ring. Such messages are triggered by a short data inconsistency due to power transients, when the engines are started. This condition, if not corrected, could lead to an undetected loss of redundan cy during flight if an affected SEC cannot control the related elevator servo control(s), possibly resulting in reduced control of the aeroplane. It was determined that, t o recover full redundancy, a reset of SEC 1 and SEC 2 must be done after engine s star t and Airbus have developed an Airplane Flight Manual (AFM) Temporary Revision (TR), published as TR 572 Issue 1.1, to provide the necessary flight crew procedure. For the reason described above, this AD requires amendment of the applicable AFM.

- Internet/Intranet. Required Action(s) and Compliance Time(s): Required as indicated, unless accomplished previously: (1) For aeroplanes equipped with SEC hardware C P/N B372CAM0100 with software standard 12 2 , 124 or 125 (P/N B372CAM0101, P/N B372CAM0102 or P/N B372CAM0103 ) on SEC position 1 or 2, or both , within 30 days after the effective date of this AD, amend the applicable AFM, Section Normal Procedures / Pre

- flight Checks, as indicated in Table 1 of this AD, inform all flight crews and, thereafter, operate the aeroplane accord ingly. The AFM amendment as required by this AD can be accomplished by inserting a copy of this AD, or Airbus AFM TR 572 issue 1.1, into the applicable AFM

. Table 1

– AFM Temporary Revision
AFTER START NORMAL PROCEDURE After both engines start: Turn OFF then ON SEC 1 and SEC 2 one after the other.

Note: Airbus Operations Engineering Bulletin OEB

- 50 provides additional information on the subject addressed by this AD. (2) Modification of an aeroplane by installation of SEC (hardware), having a not her P/N than those mentioned in paragraph (1) of this AD, on both SEC position s 1 and 2 , allows removal of the AFM TR as required by this AD for that aeroplane

. SEC hardware C with software standard 126 (Airbus modification 161208) , identified by P/N B372CAM010 4 , is a n acceptable correction

. ( 3 ) For all aeroplanes: From the effective date of this AD, do not modify an aeroplane by installation of SEC hardware C P/N B372CAM0100 with software standard 12 2 , 124 or 125 (P/N B372CAM0101, P/N B372CAM0102 or P/N B372CAM0103) on SEC position 1 or 2, or both , unless the AFM of the aeroplane is amended, concurrently with that modification, as required by this AD.
