AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/AIRCON/3.

 

Requirement:

CANCELLED.

 

This AD is cancelled on 24 September 2009.

Background:

This unique Australian AD raised in 1968 required an inspection to dynamically balance cabin supercharger rotors in accordance with technique specified in the approved overhaul manual.

Compliance was:  New Rotors:  Before initial installation in an aircraft.  Used Rotors:  Before installation in an aircraft following each overhaul completed after
30 January 1968.

The requirements of this AD have been superseded by legislation requiring compliance with approved maintenance data; therefore this AD is considered to be no longer required.

Delegate of the Civil Aviation Safety Authority
