By virtue of being a primary builder, a primary builder is permitted to conduct maintenance to the extent permitted by the Regulations on the aircraft of which they are the primary builder or conduct maintenance on a similar aircraft.

General Competency Rule for AMT Certificate Holders:

The General Competency Rule is a cornerstone of achieving safe aircraft operations – in this context, through the conduct of correct and accurate aircraft inspection and maintenance activities. Before commencing any activity permitted by an AMT certificate or endorsement, a person must ask themselves ‘Am I capable of conducting this activity competently?’

This is the equivalent of the principle of the CASR Pt 61.385 General Competency Rule as it applies to pilots, or similar to the medical ‘fitness to fly’ question.

It means that an AMT holder needs to be sure they are competent to inspect and maintain IAW their AMT certificates and endorsements.

The General Competency Rule in respect of aircraft inspection and maintenance activities covers but is not limited to:

    • – maintaining aircraft records, certification and use of data
    • – use of tools and the conduct of basic practices and procedures required to conduct aircraft maintenance and aircraft periodic or any other inspection

The General Competency Rule has been included for two reasons. The first is to ensure that all persons holding AMT certificates consider whether they are competent to exercise the conferred privileges. This is about good practice.

The second relates to the anticipated inclusion of a General Competency Rule in the for-shadowed CASR Pt 43 legislation.

AMT Certificate Holders should also consider how familiar they are with a particular inspection and maintenance activity if they have not conducted that activity for some time.
