                For the purpose of this AD, a bulk strip of an engine shall be carried out by an organisation approved for the purpose and in accordance with approved data.  CASA Airworthiness Bulletin (AWB) 85-005 elaborates on elements of an engine bulkstrip, where manufacturer's instructions are not available.

                Charter Operations:  Operations as detailed in Civil Aviation Regulation CAR 206 (1) (b).

                Overhaul:  This definition addresses the issue of varying definitions of overhaul and for the purpose of this AD, when carrying out an overhaul of a piston engine or a component necessary for the operation of the engine, the overhaul shall be carried out by an organisation approved for the purpose and in accordance with the engine and component manufacturer's published overhaul procedures; and / or other approved data, where manufacturer's data is not available.

                Private operations:  Operations as detailed in Civil Aviation Regulation (CAR) 2 (7) (d) and 2 (7A).

                Schedule 5:  Schedule 5 is the CASA maintenance schedule as described in Civil Aviation Regulations 1988.

                This Amendment becomes effective on 15 January 2009.

Background:  This Airworthiness Directive introduces condition checks for engines maintained in accordance with CASA maintenance schedule (CAR 42B).  This AD also mandates the overhaul periods for engines engaged in charter operations reflecting CASA policy related to the aircraft engaged in fare-paying passenger operations.

             Amendment 10 excluded compression-ignition engines from applicability list.  The current amendment clarifies the requirement for time between overhaul for engine components and makes some editorial changes, where appropriate.
