AIRWORTHINESS DIRECTIVE For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/PROP/1 Amdt 1 and issues the following AD under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section. Propellers - General AD/PROP/1 Amdt 2 Propellers - Overhaul 12/2003 Applicability: All propellers; other than propellers installed in: 1. Aircraft administered by an approved sports aviation body; and 2. Aircraft administered by the Australian Sport Rotorcraft Association; and 3. Aircraft issued with a special certificate of airworthiness under Civil Aviation Regulation (1998) 21.189 (1) (a) (ii); and 4. Aircraft issued with an experimental certificate under Civil Aviation Regulation (1998) 21.195A; and 5. Aircraft maintained under a system of maintenance. Requirement: Overhaul: Propellers, and components as listed in the propeller manufacturer's parts catalogue, shall be overhauled by an approved organisation using the manufacturers overhaul procedures, or other approved data. Compliance: Overhaul: Commencing the effective date of this Directive the propeller shall be overhauled in accordance with: The propeller manufacturer's published TBO; or The CASA TBO period as listed in Appendix 1 of this Directive. Note 1: Where the manufacturer provides supporting data in allowing a temporary overrun to the published Time Between Overhaul (TBO) the operator can use the data provided. This Amendment becomes effective on 27 November 2003. Background: This amendment has been issued to detail which propellers are applicable to the Directive, details the standards required for overhaul and the required time between overhauls. References to minimum standards other than approved data have been removed and options for the compliance with the overhaul period have been included in the addition to the existing CASA published TBO period. This Directive was issued to establish time in service periods and minimum overhaul requirements for propellers installed in Australian registered aircraft. Amendment 1 of this Airworthiness Directive became effective on 29 January 1988. The original issue of this Directive became effective on 1 January 1988. Jim Coyne Delegate of the Civil Aviation Safety Authority 17 October 2003 The above AD is notified in the Commonwealth of Australia Gazette on 5 November 2003.

Note 8: The start date for Calendar Years will be from the date the propeller is first installed on an engine. Propellers with zero hours since new or overhaul that have been in long term storage have additional inspection requirements. These are specified in Hartzell's Standard Practice Manual No 202A.
