With the aim of a new aircraft development, single engine four-seater aircraft with fixed landing gear, analysis of the existing structure has been conducted. Analysed subject was earlier produced UTVA 75 structure, which has been used as the basis of the new aircraft prototype. Elements of the structure were tested with different Non-Destructive Testing (NDT) methods. This paper describes condition of existing structure and its test results, as well as necessary repairs and replacement of the damaged parts, in order to extend life cycle of the structure.
