You must also be aware of any overhaul life limits. Say for example you remove a part from a turbine module, which has a 3500 hour TBO, the removed part has that TBO also.
If the part has run 3400 hours and you fit it to a turbine which has run 1000 hours since overhaul, the part will over-run its TBO if left installed for more than 100 hours.
If we are to swap parts between engines, we overhaul inspect them, tag them and they can be used on any other engine.
