the c.570 had a square section fuselage. its -long forward part, reaching aft to the wing trailing edges, housed the crew and up to eighteen troops and was built with aluminium longerons and frames, skinned in light alloy. there was a cabin in the nose for a crew-member who acted as navigator, bomb aimer and second pilot and behind that, ahead the engines, a well glazed pilot's cabin with side-by-side seating. immediately behind the pilot was a cabin for the wireless operator and also four passengers. next came the main cabin, which seated fourteen men and finally a small cabin for any injured. the distribution of the crew may have depended on the designated role, e.g. transport or bomber, as "flight" describes a different arrangement. access to the forward cabins was via a large port-side door. the main cabin had another large door on the starboard side at the rear; there was also a trapdoor large enough for four parachutists to leave together. the rear part of the fuselage was a welded chrome-molybdenum steel tube girder, fabric covered over a light wooden frame.
