A simplified method of lifetime monitoring of aircraft engines key components suggested, designed to account for lifetime in case of temporary disability automated software system. The method is based on use of well-known simple work off counter and allows partially taking into account the influence of engine operating conditions, particularly the temperature at the inlet to the engine, on the number of worked off standard operating cycles . By the example of AI-450-MS major engine parts showed that the proposed simplified method of monitoring makes it possible to reduce the errors level of well-known simple work off counter up to two times.

Key words: lifetime, monitoring, damaging, resource counter.
