Airworthiness Directive · Amendment 39-19746 · Fuel
The Boeing Company Airplanes
This AD applies to all The Boeing Company airplanes, certificated in any category, identified in paragraphs (c)(1) through (5) of this AD.
(1) Model 737-300, -400, -500, -600, -700, -700C, -800, -900, and -900ER series airplanes.
(2) Model 757-200, -200PF, -200CB, and -300 series airplanes.
(3) Model 767-200, -300, -300F, and -400ER series airplanes.
(4) Model 777-200, -200LR, -300, -300ER, and -777F series airplanes.
(5) Model 787-8 and 787-9 airplanes.
The FAA is adopting 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 series airplanes; Model 767 series airplanes; Model 777 series airplanes; and Model 787-8 and 787-9 airplanes. This AD was prompted by reports of fuel crossfeed valves failing to open when activated during flight. This AD requires, for certain airplanes, revising the existing airplane flight manual (AFM); and for certain other airplanes, revising the existing minimum equipment list (MEL) to do an operational check of the fuel crossfeed valve prior to each extended operations (ETOPS) flight if one fuel crossfeed valve (or the fuel balancing system on Model 787 airplanes) is inoperative. The FAA is issuing this AD to address the unsafe condition on these products.
For airplanes identified in paragraph (c)(1) of this AD: Within 120 days after the effective date of this AD, do the actions specified in paragraphs (g)(1) and (2) of this AD.
(1) Revise the “Extended Range Operations” subsection of the “Fuel System Limitations” section of the Section 1 Certificate Limitations of the existing airplane flight manual (AFM) by incorporating the information specified in figure 1 to paragraph (g)(1) of this AD. This may be done by inserting a copy of this AD into the existing AFM. When a statement identical to that in figure 1 to paragraph (g)(1) of this AD has been included in the “Extended Range Operations” subsection of the “Fuel System Limitations” section of the Section 1 Certificate Limitations of the general revisions of the existing AFM, the general revisions may be inserted into the existing AFM, and the copy of this AD may be removed from the existing AFM.
(2) Revise the “Extended Range Operations” section of the Section 3 Normal Procedures of the existing AFM by incorporating the information specified in figure 2 to paragraph (g)(2) of this AD. This may be done by inserting a copy of this AD into the existing AFM. When a statement identical to that in figure 2 to paragraph (g)(2) of this AD has been included in the “Extended Range Operations” section of Section 3 Normal Procedures of the existing AFM, the general revisions may be inserted into the existing AFM, and the copy of this AD may be removed from the existing AFM.
