6.6 Identification of CASA examiners (DAMEs, DAOs and COs)

Aviation Reference Number

Each designated examiner (including approved locum examiners) requires an individual aviation reference number (ARN), which must be obtained from CASA. Find out about applying for an ARN.


Locum approval must be obtained from CASA prior to the dates requested. CASA requires an email request including the requested date, the full name and contact details, CV, and evidence of current medical registration of the proposed locum. Once locum approval is gained in writing (by the issue of a CASRs 67.055 / 67.075 declaration that the locum is taken to be a DAME or DAO), the locum is able to perform aviation medical examinations and/or ophthalmological examinations using an issued non-regular examiner number.

Under the CASR, such locums are treated the same as DAMEs and DAOs in terms of indemnification, rights and responsibilities. Locums are required to abide by the Conditions of Appointment.
