Homebuilt aircraft are airplanes that individuals construct themselves, often from kits or plans. These aircraft can vary widely in design, size, and purpose, ranging from simple gliders to complex powered planes. Builders typically use materials like aluminum, wood, and composite materials, and they must adhere to safety regulations set by aviation authorities. Many enthusiasts enjoy the challenge and satisfaction of creating their own aircraft, often joining communities or organizations like the Experimental Aircraft Association (EAA) for support and resources. Homebuilt aircraft can be a cost-effective way to experience flying, allowing builders to customize their planes to meet personal preferences and needs.
