Amiot 340 / 341

After its Amiot 143, the company produced the Amiot 340.01, modified from the long-range postal Amiot 341. First flown in December 1937 with two 686-kW (920-hp) Gnome-Rhone 14N-0/1 radials. Trials revealed the need for a fourth crew member, 761-kW (1,020-hp) 14N-20/21 engines, and a dihedralled tailplane with endplate vertical surfaces. This resulted in the Amiot 351.01.
