Fatigue review final report: implementation considerations

Closes 22 Apr 2018

Opened 21 Mar 2018


A team of leading international specialists has confirmed the need to modernise Australia’s fatigue rules for air operators and pilots.

The CASA Board has released the final report of the independent review of aviation fatigue rules for operators and pilots. It includes 24 recommendations to improve the fatigue rules contained in CAO 48.1 Instrument 2013 and their implementation.

The independent review considered the safety need for updating the rules, processes underpinning their development and communication to industry, their scientific basis and validity, international alignment, and the impact on the Australian aviation industry.

Key recommendations to improve the fatigue rules include:

  • Revising flight duty period (FDP) limitations by adopting limits more closely aligned with international averages.
  • Increasing the flexibility of the Fatigue Risk Management System (FRMS) option to enhance scalability through additional risk-based tiers.
  • Introducing a standardised approval process (other than an FRMS) to offer limited flexibility for operators to operate beyond the prescriptive limits with specific fatigue risk mitigation measures in place.
  • Removing Part 137 aerial application operations from CAO 48.1 or adopting limits from CASR Sub part 137.Q.
  • A freeze on transition dates until changes flowing from the review are finalised in CAO 48.1 and material to support industry is ready.
  • Allocating appropriate resources to plan a detailed, coordinated implementation for finalising the reform of CAO 48.1.
  • A staggered approach to the next phase of change—addressing the highest risk areas first.

Why We Are Consulting

CASA invites the aviation community to comment on the recommendations in the review's final report. This is the time for industry stakeholders to raise any implementation issues and provide feedback to CASA on the highest priorities for action.

Relevant findings from the review report are provided within the online survey. However, to understand the full context of the review we recommend you read the executive summary of the review’s final report before providing your feedback in the online survey. A copy is provided below.

Please note that CASA intends to implement key changes flowing from the review this year. To achieve this timeframe, we will not be extending the consultation period or accepting late applications.

What happens next?

After the consultation has closed, all responses will be analysed and considered. We will publish responses on this page (where people have given us permission to do so) as well as our analysis of the results.

The Aviation Safety Advisory Panel (ASAP) is the primary advisory body through which CASA directs its engagement with industry. CASA anticipates the ASAP will establish a technical working group to help review industry input on implementing the review recommendations.

Following consultation, feedback received via the CASA Consultation Hub will be provided to the technical working group for consideration prior to CASA releasing a detailed response to the review, including an implementation timetable.

CASA expects to have key changes in place during 2018.
