 Compliance: Before further flight.

           This Airworthiness Directive becomes effective on 29 November 2002.

           Background: There have been occurrences of excessive wear of the drive gears between the oil pump and the camshaft. This is due to different specifications regarding the hardness of the materials used for the manufacture of the gears. More than one manufacturer supplies the gears. Mixing of the gears can cause excessive wear and ultimately lead to the failure of the engine. This Directive addresses the problem by providing an in- service check for engines already fitted with a mixed set of gears, and a requirement for engines needing gears to be replaced at overhaul to have any gear replacements done in matched pairs.

 Delegate of the Civil Aviation Safety Authority 26 November 2002

 The above AD is notified in the Commonwealth of Australia Gazette on 29 November 2002.
