Most Airlines use a process called trend monitoring to decide when its time to change the engine or look in to what is causing a bad trend. Some engines last longer then others, They also have what are called chip detectors to check for ferrous metal in the oil, to big of a chip would require engine removal. Also they use oil samples that are sent to a lab to check for certain particle levels of material. My point is there is no exact number for each engine you could come up with just a average.

Most jet engines don't have a life span. Just repair as needed and inspect according to the manufacturer.

The best figures I have are that the Rolls Royce Trent, as fitted on some 777s, has a design life of 25,000 hours for the hot section and 50,000 hours for the rest.

It depends on what type of engine. Different aircraft use different engines depending on their function. Their lifespan is calculated in hours... how many hours it's been used in flight, etc.

The manufacturer of the engine will reccommend hours of operation before inspections, routine maint, etc. As far as total hours of operation depends on the engine, mechanic, and manufacturer.

their time goes by hours or T.T. , total time. their is a meter inside the aircraft telling the time on the engines and a stick er put on by your maintenance person who tells you when you need an overhaul. that is a fixing and upgrading of your engine.
