Airworthiness Directive · Amendment 39-13436 · Gulfstream Model G-V Series Airplanes
Gulfstream Model G-V Series Airplanes
Model G-V series airplanes, certificated in any category; equipped with a landing gear selector dump valve (LGSDV) having part number 1159SCH512-7, -9, or -19.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Model G-V series airplanes. This action requires a one-time inspection of the landing gear selector dump valve (LGSDV) to determine the serial number (S/N). For any part with an affected S/N, or for any part for which the S/N cannot be determined, this action requires replacing the LGSDV with a cleaned part having an S/N within the affected range; or replacing the LGSDV with a new or serviceable part that has an S/N outside the affected range. This action is necessary to prevent uncommanded unlocking of the landing gear, which could result in collapse of the landing gear. 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.
