               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.

               Requirement: Replace any of the above mentioned Dry Air Pumps in service ensuring that the replacement has been reworked as applicable.

               Note: FAA AD 86-01-06 and Airborne Service Letter No 30 refer.

    Compliance: Prior to the issue of the next Maintenance Release after 31 March 1986.

           Background:  The drive shafts of listed pumps may not have been correctly brazed during manufacture, and could therefore have a very short operational life.
