## EASA EMERGENCY AIRWORTHINESS DIRECTIVE

AD No

. : 2014 - 0267 - E

Date: 09 December 2014

Note: This Emergency 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 E U 748/2012 , Part 21

. A.3B. In accordance with EC 2042/2003 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 w ith the requirements of that AD , unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216 / 2008 , Article 14 ( 4 ) exemption].

. Reason: An occurrence was reported where an Airbus A32 1 aeroplane encountered a blockage of two Angle Of Attack (AOA) probes during climb , le a d ing to activation of the A lpha P rotection (Alpha Prot) while the Mach number increas ed

. The flight crew managed to regain full control and the flight landed uneventfull y. When Alpha Prot is activat ed due to blocked AOA probes, the flight control law s order a continuous nose down pitch rate that , in a worst case scenario, c an not be stopped with backward sidestick inputs , even in the full backward position. If the Mach number increases during a nose down order, the AOA value of the Alpha Prot will continue to decrease. As a result, the flight control laws will continue to order a nose down pitch rate, even if the speed is above minimum selectable speed, known as VLS. This condition, if not corrected , could result in loss of control of the aeroplane

. As the same systems are installed on A330 and A340 aeroplanes, t o address this unsafe condition , Airbus have developed a specific Aircraft Flight Manual (AFM) procedure s , which has been published in AFM Temporary Revision (TR)E ASA AD No.: 2014

. For the reasons described above, this AD requires amendment of the applicable AFM

. This is considered to be an interim action and f urther AD action may follow

. Effective Date: 11 December 2014 Required A ction(s) and Compliance Time(s) : Required as indicated, unless accomplished previously: (1) Before next flight after the effective date of this AD, amend the applicable AFM by inserting a copy of Airbus AFM A3 30 TR 5 28 “ Abnormal V alpha Prot ”, issue 1 or AFM A340 TR 529 “ Abnormal V alpha Prot ”, issue 1 , as applicable to aeroplane type and model

. Alternatively , amending the applicable AFM can be accomplished by insertin g of a copy of Appendix 1

– AFM A330 Procedure of this AD or Appendix 2

– AFM A34 0 Procedure of this AD , as applicable to aeroplane type and model , into the Section Emergency Proce dures

. (2) Concurrent with the AFM amendment as required by paragraph (1) of this AD, inform all flight crews and , thereafter , ope rate the aeroplane accordingly.
