Airworthiness Directive · Amendment 39-14315 · BAE Systems (Operations) Limited Model ATP Airplanes
BAE Systems (Operations) Limited Model ATP Airplanes
This AD applies to all BAE Systems (Operations) Limited Model ATP airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model ATP airplanes. This AD requires one-time inspections for corrosion of the engine sub-frame tubes in zone 1 and of the engine attachment struts in zone 5, and corrective action if necessary. This AD results from reports of reduced thickness in localized areas of the engine sub-frame tubes due to corrosion, and reports that corrosion may also exist in the engine attachment struts in zone 5. We are issuing this AD to prevent failure of the engine sub- frame tubes or the engine attachment struts, which could result in separation of an engine from the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 180 days after the effective date of this AD, perform X-ray (radiographic) inspections for corrosion of the engine sub-frame tubes in Zone 1 and the engine attachment struts in Zone 5, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletins ATP-54-18 and ATP-54-19, both dated March 2, 2001. Although the service bulletins referenced in this AD specify to submit inspection results to the manufacturer, this AD does not require that action.
If any corrosion is found during the inspections required by paragraph (f) of this AD: Before further flight, replace the corroded component with a serviceable component, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletins ATP-54-18 and ATP-54-19, both dated March 2, 2001; or repair the corroded component 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).
