Draft CAAP 48-01 v3.0 – Fatigue management for flight crew members

Closed 1 Sep 2019

Opened 16 Aug 2019


Following extensive consultation with the aviation community, we have finalised the new fatigue rules under Civil Aviation Order (CAO) 48.1 Instrument 2019. Links to the latest rules and a summary of consultation, including CASA’s rationale for the changes are available below:

Civil Aviation Advisory Publication (CAAP) 48-01 v3.0 provides guidance on meeting the Air Operator’s Certificate holder, Part 141 certificate holder and flight crew licence holder obligations in relation to fatigue risk management, required under CAO 48.1 Instrument 2019.

This CAAP does not provide guidance in relation to fatigue risk management systems (FRMS) which are covered by other guidance documents.

This CAAP does not cover operational aspects specific to ultra-long range operations, which are operations involving flight duty periods greater than 18 hours. CASA intends to develop additional guidance for these operations to supplement existing FRMS guidance.

Why We Are Consulting

This version of the CAAP aligns CASA guidance with changes introduced in CAO 48.1 Instrument 2019 and incorporates recommendations of the independent review team. Feedback on these changes is now being sought.

All references in this CAAP to CAO 48.1 are references to CAO 48.1 Instrument 2019.

It is important to note that we are not consulting on fatigue management policy, but rather to ensure that the CAAP provides guidance on meeting the obligations in relation to fatigue management, required under Civil Aviation Order (CAO) 48.1 Instrument 2019.

Upon completion of this consultation, CASA will commence a program to assist industry to transition to the new rules. We anticipate that there will be additional feedback as operators prepare to transition to the new rules. To address this feedback, CASA intends to initiate an extended consultation to capture feedback during transition to the new rules and continue improving our guidance.

Please note: CASA can no longer offer the option to upload files because of the potential risk of malware.

What happens next

At the end of the response period for public comment, we will review each comment and submission received through the online response form. We will make all submissions publicly available on the CASA website unless a respondent requests that their submission remain confidential. Information about how we consult and how to make a confidential submission is available on the CASA website.

When the responses to the consultation, for which consent to publish has been granted, are published, we will also publish a summary of consultation (SOC). The SOC will summarise feedback received, describe any intended changes and detail our plans for this CAAP.
