Airworthiness Directives; Bombardier Model CL-600-2B16 (CL-604) Series Airplanes

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2001-03-52 that was sent previously to all known U.S. owners and operators of Bombardier Model CL-600-2B16 (CL-604) series airplanes by individual notices. This AD requires revising the airplane flight manual to provide the flight crew with revised aft center of gravity (CG) limits. This action is prompted by issuance of mandatory continuing airworthiness information by a foreign airworthiness authority. The actions specified by this AD are intended to prevent fuel migration under conditions of acceleration and/or climb, which could result in the airplane exceeding the aft center of gravity limit, and consequent loss of control of the airplane.
