## Abstract

The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires inspecting the three-phase circuit breakers and three-phase circuit breaker panels for discrepancies; and fixing any discrepancy and replacing unserviceable units with new units, if necessary. This AD results from reports of three-phase circuit breakers overheating on in- service airplanes. We are issuing this AD to prevent failure of a three-phase circuit breaker. Such failure could prevent an electrical load from being isolated from its electrical supply, which could result in smoke or fire in the flight deck.
