CAMS 58

The CAMS 58 was a transport flying boat developed in France in the early 1930s as a successor to the successful CAMS 53. Compared to its predecessor, the CAMS 58 featured a newly designed biplane wing cellule and replaced the wooden hull with an all-metal one. Work was slow, with three years passing from the start of design work to the prototype's first flight. When the newly formed Air France showed no interest in purchasing the type, CAMS redesigned it to be powered by two pairs of engines in tractor-pusher installations. Again, no interest was forthcoming. The final iteration of the design, reverting to a single pair of more powerful engines and a wooden hull, met with only slightly more success. Air France purchased two aircraft and operated them briefly before deeming them uneconomical and withdrawing them from service.
