Valve blocks are products that are part of the aircraft flight system. This type of parts has several channels that make the fluid passage which are part of the control and operation of the system. During the manufacturing process of these products, it is necessary to open bores that allow the access of the tool that will perform the machining of the channels. After the machining process, it is necessary to seal these holes in order to ensure that the passage of the fluid works as designed. The component used to make this seal is called LEE PLUGS. The assembly process of this type of component contains some quality requirements that need to be ensured to avoid leaks and ensure the correct operation of the aircraft system. The assembly ofthis component is performed by interference and it is necessary to ensure a robust fastening system to the part can keep static during the assembly process. ln this way, the developments of fastening <levices essential to ensure the quality of the product. This work develops a methodology to validate the design of aircraft parts fixtures for the assembly process of Lee Plug. The study was developed through numerical simulation in the software Creo 3.0 and aims simulate the assembly conditions and evaluate the behavior of the part during assembly in order to verify if the modes of fixation are sufficient to ensure the stability of the part and quality the process as well
