Abstract
The aviation industry still attracting the academicians and technical teams with its unique structure. National
Academies Press (NAP) declares that the added value of an airworthy part is sixty times more than
its equivalent in the automotive industry. In another meaning, a screw that is used on an aircraft has sixty
times more price of the same one in a car. On the other hand, aviation is an industry that has stiff regulations
since it is worldwide and has a precise process. Since the aviation industry adheres to rigid
requirements, the qualification of an aviation-grade part is very important. In this study, the
information regarding the manufacturing techniques and qualification methodology of the aviation-grade
part will be provided.
