The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-8 and 737-9 airplanes. This proposed AD was prompted by a determination that the loss of ground through the P6 panel results in the failure of the standby power control unit (SPCU). The loss of the SPCU and P6 would result in the loss of significant flight crew instrumentation and displays. This proposed AD would require installing two bonding jumpers from the P6 panel structure to primary structure. The FAA is proposing this AD to address the unsafe condition on these products.
