For transport category military helicopters, what are the fatigue regulations as specified by the US and Australian regulatory bodies?

I've managed to find that FAA has FAR 29.571 (US) but this could just be for civil helicopters.

    $\begingroup$ 'Relevant regulations' is very broad.. there's manufacturing, ongoing airworthiness, operations, licensing, noise.. the list goes on and they are often integrated or combined with fixed-wing regulations. What exactly are you looking for? $\endgroup$ – Ben May 29 '17 at 9:59
  • $\begingroup$ Ben thanks for the clarifications. I'm particularly interested in the regulations related from a structural airworthiness viewpoint. $\endgroup$ – Raptor May 29 '17 at 10:32

    $\begingroup$ @Raptor, perhaps you should edit your question to only ask about Australian CASA regulations. That part of your question is specific and answerable. Your question under Q1) a) seems too broad, since a proper answer would list every applicable regulation from every possible regulatory body worldwide. $\endgroup$ – J Walters May 29 '17 at 15:23

    $\begingroup$ Ok Everyone, I've made the question super specific and look forward to your thoughts. Thank you all for your feedback and helping me to sharpen my question. Best. $\endgroup$ – Raptor Jun 1 '17 at 7:28

The US Federal Aviation Administration does not regulate aircraft owned and operated by the military services. I suspect that is the same situation with Australia's CASA.

Parameters for aircraft service life for military aircraft are defined by the manufacturer. The aircraft is designed to meet the requirements specified by the agency requiring the aircraft. This is usually expressed in flight hours, cycles or a combination of that and possibly other parameters.
