Proposed exemption – Part 145 temporary line maintenance facility approval (CD 2215MS)

Closed 10 Nov 2022

Opened 3 Nov 2022


We are seeking your feedback on our proposal to exempt Part 145 Approved Maintenance Organisations (AMOs) from the requirement to have certain new maintenance facilities approved by CASA.

We are proposing CASA approval will not be required for facilities that will be used on a temporary basis to carry out line maintenance activities.

This will bring forward corresponding outcomes from proposed future Part 145 policies. It will also reduce unnecessary administrative burden for industry and bring the Australian requirements into line with contemporary global practices.

Assessment of maintenance facilities and record keeping are important safety assurance measures associated with maintenance organisation approvals.

A condition of the proposed instrument will be the AMO has appropriate procedures for assessment of new facilities, and they have the appropriate record keeping procedures. These procedures would be included in the AMO’s exposition, enabling an individual approach to be tailored to each AMO's circumstances, and would be approved by CASA accordingly.

The exemption will be in place in November 2022.
