Airworthiness Directives; The Boeing Company Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) certain The Boeing Company Model 737-700, -700C, -800, and -900ER series airplanes. This proposed AD was prompted by a leak through the form-in-place (FiP) gasket at the engine fuel shutoff valve access panel found during a leak check. This proposed AD would require a detailed inspection of the left and right side FiP gasket at the engine fuel shutoff valve access panel, for correct sealant installation, a fluid leak test of the engine fuel shutoff valve access panels for any leak, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
