The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Challenger 300s. The AD was prompted by multiple reports of erratic electrical status indications on the pushbutton annunciators and the engine indication and crew alerting system (EICAS). Some of those reported incidents involved a momentary loss of electrical power and loss of flight displays. The AD requires modification of the DC power centers to prevent loss of electrical power, which could result in the loss of flight displays and reduced controllability of the airplane. This AD becomes effective April 15.
