History of the fatigue rules
What are the fatigue rules for operators and pilots?
Transition deadline extended – CAO 48.1 Instrument 2019
Due to the impact of COVID-19 on many sectors within the aviation industry, in April 2020 CASA extended the transition to the fatigue rules by 12 months.
Most operators will now need to comply with the new rules from 1 July 2021.
The new rules – CAO 48.1 Instrument 2019
CAO 48.1 Instrument 2019 came into effect on 2 September 2019 with transitional provisions to take place over 2019 and 2021.
The 2019 rules were developed in response to an independent review and industry consultation.
The independent review confirmed the need to modernise Australia's fatigue rules for air operators and pilots in its final report delivered to the CASA Board in March 2018.
The final report included 24 recommendations to improve and implement the fatigue rules contained in CAO 48.1 Instrument 2013.
The independent review provided an evaluation of the safety rationale for updating the rules, processes underpinning their development and communication to industry, their scientific basis and validity, international alignment, and their impact on the Australian aviation industry.

Consultation on the proposed CAO 48.1 Instrument 2019 closed on 10 February 2019. The summary of consultation – summarising the feedback received – is available, and you can read the responses to our consultation where permission has been granted to publish.
Repealed rules – available under transitional provisions
The transitional provisions permit some operators to continue operating under previous rules for a limited period of time. Links to the previous rules are provided for convenience. Please note that the Federal Register of Legislation will show these rules as 'Superceded Version'.
CAO 48.1 Instrument 2013 as amended by the July 2016 improvements
In July 2016 CASA introduced improvements to CAO 48.1 Instrument 2013 including new appendices to cover ballooning, medical transport and emergency services, and daylight only aerial work operations including helicopter mustering. CAO 48.1 Instrument 2016 (No 1) amends CAO 48.1 Instrument 2013.
