What the agency says
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.
