2011-22-02: Electrical Power

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2011-22-02 Airbus: Amendment 39-16844. Docket No. FAA-2011-0255; Directorate Identifier 2010-NM-253-AD. Effective Date (a) This airworthiness directive (AD) becomes effective November 29, 2011. Affected ADs (b) None. Applicability (c) This AD applies to all Airbus Model A300 B4-601, B4-603, B4- 620, and B4-622 [[Page 65938]] airplanes; Model A300 B4-605R and B4-622R airplanes; Model A300 F4- 605R and F4-622R airplanes; Model A300 C4-605R Variant F airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; certificated in any category. Subject (d) Air Transport Association (ATA) of America Code 24: Electrical Power. Reason (e) The mandatory continuing airworthiness information (MCAI) states: An operator reported several cases of wire damages at the pylon/ wing interface. Analysis revealed that wires damages are due to installation quality issue resulting from lack of information in installation drawings and job cards. Moreover detailed analysis has highlighted that the Low Pressure Valve (LPV) wires were not segregated by design. * * * * * If left uncorrected, the wire chafing could impact fire protection and detection system. It may also induce dormant failure on LPV preventing its closure leading to a permanent and uncontrolled fire (in case of fire ignited upstream the High Pressure Valve (HPV)). * * * * * Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless theactions have already been done. Actions (g) Within 30 months or 4,000 flight hours after the effective date of this AD, whichever occurs first: Modify the electrical installation in the pylon/wing interface on the left-hand and right- hand side by doing a general visual inspection of wires for damage and doing all applicable repairs, replace the cable tie with lacing tape, improve the electrical installation at the level of the electrical ramp, and improve the segregation of both routes of the LPV channels 1 and 2 between LPV connector and ramp; in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-24-6106, excluding Appendix 01, dated March 31, 2010 (for Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes); or Airbus Mandatory Service Bulletin A310-24-2106, Revision 01, including Appendix 01, dated April 4, 2011 (for Airbus Model A310 series airplanes). Do all applicable repairs beforefurther flight. FAA AD Differences Note 1: This AD differs from the MCAI and/or service information as follows: No differences.
