Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. This proposed AD was prompted by a report indicating that certain clip-on nuts with primer, in lieu of clip-on nuts with cadmium surface finish only (without primer), were inadvertently used to install the self-bonded saddle clamps, which support the fuel tank system tubing inside the left main, center, and right main fuel tanks. This proposed AD would require a general visual inspection (GVI) to identify affected parts, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
