Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes

Zusammenfassung

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This AD requires repetitive inspections for discrepancies of the grease and gear teeth of the radial variable differential transducer of the nose wheel steering gearbox; or repetitive inspections for damage of the chrome on the bearing surface of the nose landing gear (NLG) main fitting barrel; as applicable. And, for airplanes with any discrepancy or damage, this AD requires an additional inspection or corrective actions. This AD also adds a terminating action. The actions specified by this AD are intended to prevent incorrect operation or jamming of the nose wheel steering, which could cause reduced controllability of the airplane on the ground. This action is intended to address the identified unsafe condition.
