Airworthiness Directives; Gulfstream Model G-V Series Airplanes

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 balance weight installation of the left and right ailerons for correctly installed attachment components, and corrective action if necessary. This action is necessary to prevent separation of the balance weights of the aileron, which could result in jamming of the pilot's aileron control system, subsequent loss of aileron control, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
