Reference to this SB will be found in the Requirement document. Terminating Action The installation of actuator P/N D23090000-6 at all thrust reverser pivot doors of both engines is terminating action for this Directive. Note 2: DGAC AD 2001-361(B) R1 refers. Compliance: Remains unchanged. As detailed in the Requirement document with the effective date of 4 October 2001. This Amendment becomes effective on 30 October 2003. Background: This Directive was originally issued to require the inspection and replacement of thrust reverser actuators following evidence that some actuators had accumulated more cycles in service than allowed by qualification. This amendment has been raised in response to a revision to the DGAC AD, that includes in the applicability actuators that may have been installed whose identification cannot be positively established. Note, that the effective date for compliance with this Directive remains the same as the original issue of this Directive.
