This Airworthiness Directive becomes effective on 10 April 2002.

Background: FAA AD 2001-02-12 indicates that affected engines may have PS3 pressure line fittings that are incorrectly torque loaded. This Directive therefore requires actions contained in the FAA AD to be followed to ensure the fittings on the PS3 pressure line are correctly torque loaded to prevent the possibility of engine power loss.
