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 Special Attention Service Bulletin 737-28-1225, Revision 1, dated October 30, 2006.
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 testing the electrical resistance of the bond between the bulkhead fitting for the fuel feed line and the front spar of the left and right wings, inspecting an adjacent bonding jumper to make sure it is installed correctly, and performing corrective and other specified actions as applicable. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent arcing or sparking in the fuel tank in the event of a lightning strike, which could result in 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 60 months after the effective date of this AD, test the electrical resistance of the bond between the bulkhead fitting for the fuel feed line and the wing front spar on the left and right wings, do a general visual inspection of adjacent bonding jumpers to make sure they are installed correctly, and do all applicable corrective and other specified actions. Do all the actions in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-28-1225, Revision 1, dated October 30, 2006. All applicable corrective actions and other specified actions must be done before further flight after the electrical resistance test.
Actions done before the effective date of this AD in accordance with Boeing Special Attention Service Bulletin 737-28-1225, dated January 12, 2006; are considered acceptable for compliance with the actions required by paragraph (f) of this AD.
