Engines get changed ad hoc due to failures or pending faults but what I'm talking about is the returning of the original engines back to the original airframe. An airframe that is being scrapped for example. Seems strange as the engines will be amongst the first items to be removed.
as has been said the engines 'belong' to the aircraft so need returning. Same at any end of lease handback for engines, Apu and gear unless negotiated otherwise. Usually have to be in a preagreed condition aswell, whether that be by recently visiting the engine shop and/or confirmed by a video borescope. Otherwise they'll be big financial penalties.
Imagine if you were the owner of the newest 747 and it had 2 or 3 of the oldest engines. You wouldn't be happy.
These are the parts that will have the biggest value if the aircraft are going to be parted out.
