A life tracking system (LTS) provides a life history recording for each module of a gas turbine engine, including module type and serial number together with total use, or operating time for each module. The total use may include total actual operating hours, total operating time under known high stress conditions, a weighted total time reflecting operational parameters, or any combination of these use indicators. The module information is stored as a permanent record with the module identification (ID) in a read/write non-volatile memory which may be read by a ground based data system. As such, each engine module may be tracked, automatically, from manufacture through its total life cycle in each engine configuration and/or aircraft in which it is used, without the necessity of human recording.
