2010-23-18 Airbus: Amendment 39-16507. Docket No. FAA-2010-1102; Directorate Identifier 2010-NM-016-AD. Effective Date (a) This airworthiness directive (AD) becomes effective November 24, 2010. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A380-841, -842, and -861 airplanes, certificated in any category, with serial numbers 15, 17, 19, 20, 21, and 22. Subject (d) Air Transport Association (ATA) of America Code 36: Pneumatic. Reason (e) The mandatory continued airworthiness information (MCAI) states: During inspection in production and on in-service aircraft, a number of OverHeat Detection System (OHDS) installation non- conformities have been identified along the bleed air ducting. Some installation issues which may lead to a degraded leak detection capability have been reported. In case of hot air leakage, the potential degradation of the OHDS would not allow preventing damages to structure or components, and therefore could lead to an unsafe condition. * * * * * Nonconforming installation or a failure of the OHDS could allow undetected leakage of bleed air from the hot engine/auxiliary power unit causing damage to the airplane structure and various airplane components and systems. Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Inspection and Corrective Actions (g) Within 3 months after the effective date of this AD: Do a one-time detailed visual inspection to ensure the correct installation of the OHDS sensing elements and insulation muffs, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A380-36-8009, including Service Bulletin Report Sheet, dated December 7, 2009. (h) If, during any inspection required by paragraph (g) of this AD, any sensing element or insulation muff is found to have been installed incorrectly, before further flight, bring the installation into compliant configuration, in accordance with Airbus Mandatory Service Bulletin A380-36-8009, dated December 7, 2009.
