There is an Antonov An-2 stationed at my city's airport. I checked the tail number - it entered service in the 50s and only recently had its engine changed.

    There are stories of B52 pilots flying the same plane as their grandfather. Not just flying but still in active military service.

    I suspect that 99% of the parts have been replaced through maintenance or upgrades, but technically, it is still the same plane.

    With parts and maintenance machines can last virtually forever.
