Unsafe Condition
Erratic indications caused by contamination of electrical contacts in the left-hand (LH) direct current power center (DCPC) internal communication data bus, leading to misleading electrical system status indications (push button annunciators (PBA) and engine instrument and crew alerting system (EICAS)). This could cause the flightcrew to turn off fully operational electrical power sources, leading to partial or complete loss of electrical power, resulting in loss of flight displays and reduced controllability of the airplane.
