An aircraft can technically fly for a very long time, like the DC9's mentioned and of course the DC3, although the DC3 does not have a pressurized cabin.
|Quoting Sampa737 (Thread starter):|
With stories of metal fatigue and other problems, just how long can a plane last with continual commercial use? I ask with reference to another post regarding the DC-8s of UPS
|Quoting Prebennorholm (Reply 10):|
That doesn't harm the DC-8-7x which is the only really successful re-engined old jet airliner with modern, fairly fuel efficient and noise compliant engines.
|Quoting Bmacleod (Reply 7):|
NWA has managed to hold on to their DC-9s for over 40+ years mainly due to extensive maintenance.
|Quoting Rampart (Reply 13):|
Weren't KC-135s re-engined in the same way? (IIRC, 707s were tested in the same way, but ended up not commercially available)
