The above listed pumps were not available for installation before 1 September 1985. Therefore, new Airborne Dry Air Pumps or Auxiliary Dry Air Pumps installed prior to that date are exempt from this AD. Pumps that have been reworked by Airborne will have a white date code stamped on the pump housing near the discharge port. This will indicate that the pump complies with this directive.
