DP 1518CS – Design organisations and approval of modifications and repairs for Australian aircraft
CASA is reforming the civil aviation legislation, which includes progressively transferring and updating the regulations from the Civil Aviation Regulations 1988 (CAR) to the Civil Aviation Safety Regulations 1998 (CASR).
The regulations covering aircraft design and certification have been fully transitioned to Part 21 of CASR. The final elements were transitioned with the making of the Civil Aviation and Civil Aviation Safety Amendment Regulations 2011 (No. 1), which covered approval of modifications and repairs, and the Civil Aviation Legislation Amendment (Subpart 21.J) Regulation 2013, which covered ADOs.
CASA is carrying out a post implementation review of Part 21, with particular emphasis on the recently made Subpart 21.M – Designs of modifications of, and repairs to, aircraft, aircraft engines, propellers and appliances; and Subpart 21.J – Approved design organisations.
It has become apparent that whilst the new regulations do provide safety and cost benefits, in some cases, particularly for small organisations, simple designs and small general aviation aircraft, some of those benefits may not be realised in practice.
In addition to these issues, the European Aviation Safety Agency (EASA) has recently made significant changes to the European Implementing Rules and Certification Specifications for standard modifications and repairs. The European requirements are now similar to the requirements currently in place in the USA whereby certain kinds of simple or standard modifications and repairs do not require a design approval.
The Australian requirements for approval of design organisations and modifications and repairs are more onerous than those of Europe and the USA. CASA seeks to address this through regulatory amendment. This DP explains the considerations for selection of appropriate requirements and describes a number of potential options for changes to the regulations and the associated implementation plans.
CASA recognises the valuable contribution that industry consultation makes to the regulatory development process, and issues this DP as the next stage of development of the requirements for approval of design organisations and modifications and repairs for Australian aircraft.
