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 identified in Boeing Service Bulletin 737-28-1209, dated February 17, 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 modification of certain wire bundles located above the center fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent chafed wire bundles near the center fuel tank, which could cause electrical arcing through the tank wall and ignition of fuel vapor in the fuel tank, and result in a fuel tank 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 60 months after the effective date of this AD: Modify the wire bundles located below the passenger compartment, above the center fuel tank, aft of station (STA) 540 through STA 601 inclusive, at right buttock line and left buttock line 24.82 in accordance with the Accomplishment Instructions of Boeing Service Bulletin 737-28-1209, dated February 17, 2005. Lacing tape part number (P/N) BMS 13-54, having Type I, Class 2, Finish C, Grade D, shown in sheet 3 of Figures 5 and 6 of the Accomplishment Instructions of the service bulletin, does not exist; the correct material is BMS 13-54, having Type II, Class 1, Finish D/C, Grade D, white, or Type III, Class 1, Finish C, Grade D, white, any size.
