Abstract : This report results from a contract tasking TsAGI as follows: The contractor will report on investigation into structural issues effecting aging aircraft. One of the most important problems in aviation is the one of ensuring safe operation of aging aircraft. Up to date many Russian aircraft types have worked out their design service lives. It is impossible to replace all of old aircraft types by newer ones in the nearest future, so it seems obligatory to prolong service lives and durability of aging aircraft beyond the design goals. This requires testing the long-operated aircraft for fatigue resistance, ensuring damage tolerance of the structures with widespread fatigue damage (WFD), studying the degradation of crack resistance and fatigue strength after long-term operation, and ensuring safe operation of corrosion-damaged structures. This paper outlines the experience of dealing with the above problems in Russia.
