Fatigue Critical Components - Retirement Lives
This AD applies to each Ted Smith Aerostar, Piper Aerostar or Aerostar Aircraft model 600, 601, 601P or 602P aeroplane (the aircraft) with:
(a) a Machen-modified Lycoming IO-540 or TIO-540 series engine; and

The registered operator of the aircraft must ensure that the propeller blade is retired from service.
The propeller blade must be retired from service at or before 10 500 hours component time in service.
This Amendment becomes effective on 21 August 2013.
Hartzell Propeller Owner’s Manual No. 115N, Airworthiness Limitations refers to the mandatory propeller blade retirement life for the propeller and engine combination to which this AD applies. Associated hub parts are not affected.
The original issue of this AD established propeller blade life limits for Machen installations. It also incorporated the component retirement requirements of
Amendment 1 expanded the requirements of the AD to apply window and windshield life limits to all pressurised Aerostar models.
Amendment 2 removes the requirement relating to windshield and window life limits. The requirements for windshield and window retirement are contained in the aircraft airworthiness limitations (AWL). Subsection 9 of Civil Aviation Order 100.5 (General requirements in respect of maintenance of Australian aircraft) 2011 directs the registered operator of an Australian aircraft to comply with AWL.
The requirement 2 relating to the propeller life limit is retained unchanged.
