Also, it was built early in the stressed skin era, and designers weren't really sure how strong the airframes were, and aircraft such as the DC-3 were overbuilt.The main reason why DC-3s and C-47s remained in service for so long is mainly due to two reasons; their availability, and their reliability. The aircraft were available in such large numbers in the years following the Second World War that you could buy a few for a dirt cheap cost. Their reliability was down to two major factors; their availability and their simplicity. Spares were in huge supply and the aircraft were relatively easy to maintain.
The only two aircraft (in my honest opinion) that can be called DC-3 replacements are the HS.748 and the Convair 240 series, however, these aircraft aircraft came nowhere near close enough to the DC-3, and only truly replaced them in mainline service.
HS.748? Not really; Fokker F-27/FH-27/FH-227 was the true turboprop successor to the DC-3 for many carriers in North-America, Europe, Latin America, Australia and parts of Africa and Asia.The main reason why DC-3s and C-47s remained in service for so long is mainly due to two reasons; their availability, and their reliability.
