## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-200, -300, -400, and -500 series airplanes, that requires replacement of existing door handle mounting hub assemblies with new, improved hub assemblies. This amendment is prompted by reports of cracked or broken mounting hub assemblies for the interior door handles on the cabin doors. The actions specified by thisAD are intended to prevent cracking or breaking of the door handle mounting hub, which could result in the interior door handle breaking off while the door is being opened. In an emergency situation, this could impede evacuation of the airplane.
