Homebuilt airplanes are aircraft built by individuals and then licensed as “experimental”. They are used solely for educational or personal purposes. Many thousands of homebuilt airplanes are being flown in the world, and there are four main types.

The first is built from steel tubing which is welded together and then covered with fabric. The fabric used for these homebuilt airplanes is durable Dacron. Another type of homebuilt airplane is that made of aircraft plywood and spruce. The third homebuilt airplane is built of aluminium. This is the easiest type for an amateur to put together. The final type of homebuilt airplane is a composite airplane.

The airplane is cared from lightweight plastic foam. It is then covered with fibreglass or carbon fibre skins containing epoxy resin. This method gives the homebuilt airplane a smooth surface.
