The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This AD was prompted by a report of the lack of data to substantiate engine operability when an airplane is dispatched under a certain master minimum equipment list (MMEL) item. This AD prohibits dispatching an airplane under the operational procedures of the operator's minimum equipment list item corresponding to a certain MMEL item. The FAA is issuing this AD to address the unsafe condition on these products.
As of 60 days after the effective date of this AD: No person may dispatch an airplane under the operational procedures of the operator's minimum equipment list item corresponding to MMEL 75-33-01 (“Engine Intermediate Pressure (IP) Bleed Valves (RR)”).
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
