Airworthiness Directive · Amendment 39-14636 · Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes
Boeing Model 737-600, -700, -700C, -800, and -900 Series Airplanes
This AD applies to Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes; certificated in any category; as listed in Boeing Special Attention Service Bulletin 737-28-1199, Revision 1, dated December 15, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires replacing the fuel shutoff valve wires and conduit assemblies in the left and right engine strut aft fairing areas. This AD results from a report that an operator discovered many small chafe marks and exposed shield braid on fuel shutoff wires routed through a conduit in the wing. We are issuing this AD to prevent exposed wires that could provide an ignition source in a flammable leakage zone and possibly lead to an uncontrolled fire or explosion.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 36 months after the effective date of this AD, replace the fuel shutoff valve wires and conduit assemblies in the left and right engine strut aft fairing areas with new fuel shutoff valve wires and conduit assemblies, by accomplishing all the actions in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-28-1199, Revision 1, dated December 15, 2005.
Actions accomplished before the effective date of this AD in accordance with Special Attention Service Bulletin 737-28-1199, dated September 9, 2004, are considered acceptable for compliance with the applicable action specified in this AD.
