## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Cessna Model 750 airplanes, that requires replacement of reset circuit breakers for the auxiliary hydraulic pump system and the King KHF 950 high frequency communication system(s) with new circuit breakers. This amendment is prompted by a report from the airplane manufacturer indicating that the trip levels for the reset circuit breakers installed in the auxiliary hydraulic pump system and the King KHF 950 high frequency system(s) are too high, which can prevent corresponding high current remote control circuit breakers from tripping when excessive electrical loads are present. The actions specified by this AD are intended to prevent overloading of the affected airplane electrical wiring and circuits, which could result in a fire.
