Transportation Department, Federal Aviation Administration
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-300, -400, -500, -600, -700, -700C, -800, -900, and -900ER series airplanes; Model 757 airplanes; Model 767 airplanes; Model 777 airplanes; and Model 787-8 and 787-9 airplanes. This proposed AD was prompted by reports of fuel crossfeed valves failing to open when activated during flight. This proposed AD would require, for certain airplanes, revising the airplane flight manual (AFM); and for certain other airplanes, revising the minimum equipment list (MEL) to do an operational check of the fuel crossfeed valve prior to each extended range operations (ETOPS) flight if one fuel crossfeed valve (or the fuel balancing system on Model 787 airplanes) is inoperative. We are proposing this AD to address the unsafe condition on these products.
