## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Model 60 airplanes. This AD requires modifying the aircraft cabin heat control wiring. This AD is the result of an incident on one of the affected airplanes where the circuit control that operates the aircraft cabin heater overheated and caused the cabin heater to shut down during in- flight operation. The actions specified by this AD are intended to prevent this circuit from overheating because of the current wiring design, which could result in possible smoke/fire if the heating system continued to operate in an ``over-temperature'' condition.
