## Abstract

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.
