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:
- 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.

Note 2: At each 500 hours time in service between overhaul and on any other occasion when its removal is necessary, the dome assembly shall be partially dismantled and cleaned of carbon and sludge.
Note 3: Attention is drawn to the regular inspection requirements for fixed pitch propellers contained in Civil Aviation Orders Part 107 - Airworthiness Directive AD/PFP/1 Amdt 3.
Note 4: For Hartzell propellers fitted to aerobatic aircraft each hour engaged in aerobatics shall be counted as equivalent to 2 hours normal flight time.
Note 5: Refer Dowty Rotol SB 61-996 Revision 18 for details of the TBO requirements and life sampling programme.
Note 6: For all model Hartzell propellers installed on Franklin 6A8-215, Bristol Siddeley Gipsy Queen 30 MK-2, Jacobs R-755 and Ranger 6-440-( ) engines, time in service between overhaul shall be 1000 hours or 10 years calendar time whichever occurs first. For all model Hartzell propellers installed on Franklin 6( )-355 and 6( )-350, time in service between overhaul shall be 1500 hours or 10 years calendar time whichever occurs first.
Note 7: Refer also to specific aeroplane schedules in the CAO 105 series for any applicable ultimate blade life limits.
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.
Note 9: For mt-propeller overhaul, flying hours or calendar time, storage, overspeed, ground strike or aerobatic requirements refer mt-propeller Service Bulletin 1 Revision X.
Note 10: 2400 hours TBO may apply. Refer McCauley Service Bulletin 137W.
