## Abstract

We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Model GVI airplanes. This AD requires revising the Normal and Abnormal Procedures sections of the airplane flight manual (AFM). This AD was prompted by potential failure of the bi-directional data bus that sends and receives critical signals between the flight control computer (FCC) and the flight control surfaces. We are issuing this AD to address the unsafe condition on these products.
