Regulation change designed for success

ADO approval gives organisations, rather than individuals the responsibility for aircraft design and modification

CASA is enabling a new era for the aviation industry in Australia by introducing approved design organisations (ADO). Under this new system of approval, design organisations will be able to:

  • independently give advice for minor damage
  • perform approvals of design
  • undertake certification of designs to CASA, and issue experimental certificates.

Introduced in March 2014, the new Civil Aviation Safety Regulation Subpart 21.J replaces the existing system where CASA approves all aircraft designs either by itself or through approved persons who act on its behalf.

The transition from approved persons to approved design organisation aligns the approval system with that of Europe.

Qantas received the first approval, in November 2014, but  the scheme also benefits smaller organisations. The changes decrease the reliance on the individual and provide credibility for the company to bid for work in larger projects rather than on a case-by-case basis as done now.

The new system also has potential to lead to mutual recognition of design organisations by aviation regulators including EASA and the FAA. Worldwide recognition has the potential to open many new markets for Australian ADOs.
