Abstract: This paper describes the changes and additions to technical documentation, debugging and improving the technological process of building assemblies. Modification of the diaphragm of the wings will be technological processed and that document must be fully updated document, which entails a further operational planning for commissioning in the manufacture of aircraft, as well as quality control and standardization process of the mentioned elements. Amendments of the technological process is carried out directly in all working copies of the technological process, because this is case of an urgency. It will be explained the occurrence of modifications to the diaphragm of wings, standards related to it, factors affecting the economy in exploiting (less costs) and productivity of that element.

Key words: modification, technical procedures, quality control, standardization of the elements, economy of operation, and productivity.
