Airworthiness Directives; Dornier Luftfahrt GmbH Model 228-212 Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Dornier Luftfahrt GmbH (Dornier) Model 228-212 airplanes that have a certain brake assembly installed. This AD requires you to inspect the brake housing subassembly for cracks, nicks, or corrosion (referred to as damage). This AD also requires you to replace damaged brake housing assemblies and modify the torque take-out cavity. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to detect and correct damage to the brake housing assembly, which could result in failure of this assembly. Such failure could lead to loss of braking action on landing and possible loss of control of the airplane.
