## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Gulfstream Model G-V series airplanes, that requires repetitively replacing the existing nose wheel steering actuator with a new or reworked actuator having the same part number. The actions specified by this AD are intended to prevent loss of nose wheel steering control without a corresponding alert message annunciation due to the effects of moisture intrusion into the rotary variable displacement transducer (RVDT) inside the steering actuator, and consequently, an over steering condition. If an over steering condition were to occur during landing, the airplane could depart the runway. This action is intended to address the identified unsafe condition.
