A new aircraft has appeared at the flying troops of the Hungarian Defence Forces which also brought about the emergence of a new maintenance strategy. The new strategy meant a switch of the operating technology at the same time, and it also posed a set of management problems, especially in certain stages of the conversion process. The morphostatic or morphogenetic nature of the change has been brought up as a fundamental question; the successful realization of this change requires various management procedures. In the present study I make an attempt to compare the two operation strategies that are simultaneously present, from which it may emerge that what processes are affected by the changes and at what level they are affected. In my view the usefulness of the analysis lies in the fact that the efficiency of integrating a new aircraft into the system may considerably increase in the future.
