Abstract
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.
