             This Airworthiness Directive becomes effective on 5 November 2007.
Background:  This AD is the result of continuing failures of the hydraulic pump outlet tubes and the need to incorporate improved design.  The issuing of this AD is to prevent failure of the hydraulic pump outlet tube and consequent leaking of hydraulic fluid.  Such leakage could result in a fire.  There is also a risk of loss of hydraulic system functions including normal gear extensions, speed brakes, roll spoilers, lift dump, and normal brakes.
