Owner produced parts are components that an aircraft owner fabricates themselves, often for use in maintaining or modifying their own aircraft. However, there are important limitations on selling these owner produced parts. According to FAA operational guidance, while an owner may produce parts for their own use, the sale of these parts to others is restricted. This regulatory compliance measure ensures that parts entering the market meet safety and quality standards established by the FAA. Owners should be aware that producing parts for personal use does not grant the authority to distribute or sell those parts commercially, as this could violate FAA regulations and potentially compromise aircraft safety.
