Authorised persons (APs) may carry out the following design activities for aircraft or aeronautical product or alterations to aircraft or aeronautical products:
- approval of technical data (CASR 21.009)
- approval of changes to aircraft flight manuals (CASR 21.006A)
- approval of minor changes in type design (CASR 21.095)
- modification/repair design approvals (CASR Subpart 21.M including 21.437)
- variations of supplemental type certificates (CASR 21.120B).
Instrument of Appointment
An Instrument of Appointment (IOA) details the scope of design activities that an AP is able to carry out.
To become an AP for design, you must:
- develop a design approval procedures manual (DAPM)
- be employed or contracted by an organisation that has a DAPM.
The DAPM describes your design activity processes.
Design approval procedures manual
You must prepare a DAPM to become an AP.
Alternatively, you may work for or contract to an organisation that is developing a DAPM or has one that is already approved. In the latter case, the DAPM may need amendments to reflect the addition of another AP.
includes guidance material for the approval of modifications and repairs under CASR Subpart 21.M.
You can find further advice and DAPM guidance in the CASA Design Instrument of Appointment Procedures Manual.
Assessment timeframes vary and rely on:
- when we receive your payment
- the quality of your documents
- the availability of our resources.
We will also interview applicants to assess knowledge of the CASRs and the specialities included in the requested scope. We may do an on-site inspection to verify the procedures in a new DAPM.
If you meet the regulatory requirements, we will issue an Instrument of Appointment. The certificate contains the:
- certificate number
- name and address of the organisation or individual (as applicable)
- approved design activities and any limitations
- approved scope including the types of aircraft, technical specialities, and any conditions.
