Airworthiness Directive · Amendment 39-12327 · Gulfstream Model G-V Series Airplanes
Gulfstream Model G-V Series Airplanes
Model G-V series airplanes, serial numbers 501 and subsequent, certificated in any category.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
