The revision of this AC is not a result of the newly made Part 139 which came into effect in August 2020.

A copy of the draft AC is provided below and within the consultation. Please read the AC before providing your feedback in the online survey.
What happens next

We will make all submissions publicly available on the CASA website, unless you request your submission remain confidential. We will also publish a Summary of Consultation which summarises the feedback received, outlines any intended changes and details our plans for the AC.
