## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to Raytheon Aircraft Company (Raytheon) Beech Models 65-90, 65- A90, B90, and C90 airplanes that incorporate a certain engine and propeller configuration. This AD prohibits you from operating any affected airplane with this engine and propeller configuration and prohibits its future installation. Results of an accident investigation involving one of the affected airplanes reveals installation discrepancies with the engine and propeller configuration. These discrepancies, if not corrected, could lead to engine failure and the inability to feather the propeller. The actions specified by this AD are intended to prevent an uncontained engine failure due to suspect engine and propeller installation, which could result in loss of control of the airplane.
