Amateur built and experimental aircraft
Amateur-built aircraft can be built from scratch, based on original or established designs, or from a kit. If a kit is used, the builder must have completed the majority of the build for it to be considered an amateur-built aircraft.
Amateur-built aircraft can be registered with CASA as VH registered aircraft. If they meet certain performance, weight and design limitations, they can be registered with a self-administering organisation. We work with a number of self-administering organisations to provide support for aircraft builders through training, test flights and airworthiness administration and approval processes.
Experimental and amateur-built aircraft include any aircraft that is fabricated and assembled by anyone for their own education and/or recreation.
There are hundreds of different designs and models of aircraft across the Australian amateur-built fleet. These include piston and jet-powered, single or twin-engine, and high-performance aircraft but may also include amateur-built balloons, gliders, gyroplanes or helicopters.
As designs and technology have developed, the materials used to build aircraft have also advanced, with the traditional wood, fabric and metal tubing construction techniques of the 1930s often giving way to new construction methods using advanced and lightweight composite materials.
For further information and guidance relating to VH-registered amateur-built aircraft, see CASR subpart 21 certification and airworthiness requirements for aircraft and parts.
