Statistical data clearly points out compressor train outage as one of the main reasons for the breakdown of aircraft power units. Outages are caused by various factors, including material conditions as the main one. Therefore, structural ultimate strength analysis of constructional raw material properties used in the production process of such an important part of an engine is not only of tremendous significance during the designing phase but also in a research phase and expertise associated with emergency situations. Considering the above-mentioned factors the article presents the outcomes of chemical composition, morphology, and phase structure of metallic material used to produce first row fan blades of RD-33 turbine jet engine, which is (currently) used by the Polish Air Force. Apart from typical material structure analysis, also the basic mechanical strength properties of materials have been determined including hardness, tensile, and impact tests. These may now constitute the basis for the analysis of substitute materials selection allowing the production of analyzed engine part.
