Abstract
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-8 and 737-9 airplanes. This AD was prompted by manufacturing design changes to certain metallic support panel assemblies installed in the flight deck, which resulted in insufficient electrical bonding of the panels and consequent insufficient electrical grounding of installed equipment. This AD requires modification of the electrical bonding of these assemblies to provide sufficient electrical grounding for equipment installed in the flight deck. The FAA is issuing this AD to address the unsafe condition on these products.
