Benefits of the aircraft commonality are elaborated in the following paper by applying advantages offered by commonality which are represented thought reduction of operational costs; those are calculated by means of making use of the modified Boeing Airplane Economics Group methodology. Similarities of the newly acquired and existing aircrafts are analyzed in the operator’s fleet, which consists of five TJ50 (existing) and three TJ70 (new), thought crew training and spare parts costs. For determining the aircraft cost the methodology developed by Roskam J. for level 2002, is being used. Crew training costs are explored on the base of principal CCQ-Cross Crew Qualification or MFF-Mixed Fleet Flying. Spare parts with commonality are determined on the percent basis of the spare parts value and are the same for both existing and newly acquired aircraft. In this paper the percentage of the common spare parts value is defined as the commonality coefficient. Benefits of the commonality are represented in terms of reduction of flight crew costs, the total cost per flight and decreasing cost of ownership.
