- What it does
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-700, -700C, -800, and -900ER series airplanes. This 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 AD requires 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 issuing this AD to address the unsafe condition on these products.
