Airworthiness Directives; Raytheon Corporate Jets Model BH/HS 125-600A and -700A Series Airplanes

Résumé

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Raytheon Corporate Jets Model BH/HS 125-600A and -700A series airplanes. This proposal would require installation of two new circuit breakers in the 6 volt output circuits of the flight deck lighting transformers on electrical Panel `RY,' below the right pilot's seat. This proposal is prompted by a report of smoke in the flight deck due to a lighting transformer 6 volt output circuit short circuiting to ground. The actions specified by the proposed AD are intended to prevent smoke or fire in the flight deck due to inadequate circuit protection for 6 volt circuits of the flight deck lighting transformer.
