Project OS 02/03 - Fatigue risk management systems
Previously, Part 48 CAOs (comprising CAO 48.0, CAO 48.1, CAO 48.2, CAO 48.3 and CAO 48.4) contained flight and duty time limitations and related rules for various members of an aircraft’s flight crew. Exemptions from the requirements of these CAOs were also issued to some operators under paragraph 4.1 of CAO 48.0, but subject to conditions amounting to revised, standardised flight and duty time limitations.
In July 2011, the International Civil Aviation Organization (ICAO) issued Standards and Recommended Practices (SARPs) for fatigue risk management for flight crew members, including standards for FRMS. The 2013 CAO was CASA’s regulatory response to the ICAO SARPs and it was informed by advanced international scientific understanding of fatigue, fatigue risk and fatigue risk management. The objective was to improve aviation safety, address known risks, and maintain Australia’s reputation for safety in aviation.
The 2013 CAO prescribed both specified flight and duty time limitations, minimum rest requirements and fatigue self-management obligations, while also offering relevant operators the opportunity to develop a customised, data-driven and scientifically informed FRMS. Thus, AOCs operating outside of prescribed limitations could tailor their operations based on a scientifically supported risk managed approach.
In 2017 CASA’s Board commissioned an independent review of the fatigue rules for operators and pilots contained in Civil Aviation Order (CAO) 48.1 Instrument 2013. In its final report delivered to the CASA Board in March 2018, the independent review team confirmed the need to modernise Australia’s fatigue rules for air operators and pilots. The final report included 24 recommendations to improve and implement fatigue rules for Australian operators.
The fatigue rules for air operators and pilots were updated as part of CASA's regulation reform program, which seeks to align Australia’s rules with international standards, improve aviation safety, address known risks, and maintain our reputation for safety in aviation.
Civil Aviation Order 48.1 Instrument 2019 (CAO 48.1 (2019)) was signed on 13 August 2019.
CAO 48.1 (2019) makes use of international standards concerning fatigue, reflects advanced international scientific understanding of fatigue, fatigue risk and fatigue risk management, and is informed by an independent panel of experts appointed by CASA.
The new CAO is effectively a remake of the 2013 CAO but with significant revisions and amendments arising from the independent review and industry consultation.
CASA has commenced implementation of the new rules and will be updating guidance material.
