             This Airworthiness Directive becomes effective on 12 April 2007.
Background:  The issuing of this AD is to prevent failure of the No. 3 bearing, which could result in an in-flight shutdown and smoke in the cockpit and cabin.  The smoke is a result of oil escaping from the bearing compartment due to a fracture of the No. 3 bearing race.
