2009-23-05 Airbus: Amendment 39-16077. Docket No. FAA-2008-1215; Directorate Identifier 2008-NM-072-AD. Effective Date (a) This airworthiness directive (AD) becomes effective December 14, 2009. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A318-111, A318-112, A319- 111, A319-112, A319-113, A319-114, A319-115, A319-131, A319-132, A319-133, A320-111, A320-211, A320-212, A320-214, A320-231, A320- 232, A320-233, A321-111, A321-112, A321-131, A321-211, A321-212, A321-213, A321-231, and A321-232 series airplanes, certificated in any category; equipped with EIS2 (electronic instrument system 2) standard S4.2 (DMC disk part number F1419418) installed by Airbus Modification 34571, or Airbus Service Bulletin A320-31A1220; except those airplanes on which Airbus Modification 35270 or Airbus Modification 36725 has been embodied in production. Subject (d) Air Transport Association (ATA) of America Code 31: Instruments. Reason(e) The mandatory continuing airworthiness information (MCAI) states: Two incidents have occurred due to the lack of visibility on the Primary Flight Display (PFD) of the Traffic Alert and Collision Avoidance System (TCAS) indications. EIS2 standard S7 introduces modifications to the vertical speed indication to improve the legibility in case of TCAS Resolution Advisory. The modifications consist in changing the colour of the needle and increasing the width of the TCAS green band. This AD supersedes AD 2006-0108 [dated May 3, 2006]. Also, as all aircraft in this AD applicability have been retrofitted to at least S4.2 standard, the operational limitations contained in the Compliance paragraph 2. of AD 2006-0108 have already been addressed. This AD therefore mandates the installation of the improved EIS2 standard S7. We are issuing this AD to prevent possible mid-air collisions due to lack of visibility of TCAS indications on the PFD. Actions and Compliance(f) Unless already done, do the following actions. (1) Within 12 months after the effective date of this AD, install EIS2 standard S7 (DMC disk part number F1461768), in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A320-31-1276, Revision 01, dated March 5, 2008. Operators may stow software media in locations other than those described in the service bulletin. (2) Installations done before the effective date of this AD in accordance with Airbus Service Bulletin A320-31-1263, Revision 01, dated July 20, 2007; Airbus Service Bulletin A320-31-1263, Revision 02, dated August 10, 2007; Airbus Service Bulletin A320-31-1263, Revision 03, dated November 23, 2007; or Airbus Service Bulletin A320-31-1276, dated April 18, 2007; are acceptable for compliance with the requirements of paragraph (f)(1) of this AD. FAA AD Differences Note 1: This AD differs from the MCAI and/or service information as follows: This AD does not include the operational limitations specified in paragraph 1 of the MCAI. The MCAI carried these limitations forward from European Aviation Safety Agency (EASA) Airworthiness Directive 2006-0108, dated May 3, 2006. The FAA-approved Master Minimum Equipment List (MMEL) already contains these and more restrictive operational limitations, and we previously determined that no action was required on our part regarding this provision of EASA AD 2006-0108. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, ANM- 116, International Branch, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Tim Dulin, Aerospace Engineer, ANM-116, International Branch, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-2141; fax (425) 227-1149. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120- 0056. Related Information (h) Refer to MCAI EASA Airworthiness Directive 2008-0032, dated February 21, 2008; and Airbus Mandatory Service Bulletin A320-31- 1276,Revision 01, dated March 5, 2008; for related information.
