AD 2005-20-22 Airworthiness Directives; BAE Systems (Operations) Limited Model ATP Airplanes

Models named: ATP. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to all BAE Systems (Operations) Limited Model ATP airplanes, certificated in any category.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Repetitive Inspections and Corrective Actions (f) Within 18 months after the effective date of this AD, perform detailed inspections for environmental damage, including but not limited to corrosion, of the fuselage and wing structure and any applicable corrective action in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletin ATP-51-001, dated August 14, 2002, except as provided by paragraph (g) of this AD. Any applicable corrective actions must be accomplished before further flight. Thereafter, repeat these inspections at intervals not to exceed those specified in the ATP Maintenance Review Board Report and the Maintenance Planning Document, as applicable, in accordance with the service bulletin. Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.” Exception to Service Bulletin Instructions (g) If damage is found that is outside the limits specified in the structural repair manual, as referenced in BAE Systems (Operations) Limited Service Bulletin ATP-51-001, dated August 14, 2002, and the service bulletin specifies reporting the details of the damage to In-Service Engineering and asking for repair instructions: Before further flight, repair the damage in accordance with a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Civil Aviation Authority (or its delegated agent). No Reporting (h) Although British Aerospace ATP Service Bulletin ATP-51-001, dated August 14, 2002, specifies reporting inspection results to the manufacturer, this AD does not require that action. Alternative Methods of Compliance (AMOCs) (i)(1) The Manager, International Branch, ANM-116, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19.

This AD results from information indicating the potential for environmental damage of the fuselage and wing structure. We are issuing this AD to detect and correct such damage, including corrosion, in the fuselage and wing structure, which could result in cracking and consequent reduced structural integrity of the fuselage and wing structure.
