Continuing to improve upon the Couzinet 100, a light transport aircraft intended for touring flights, René Couzinet developed the Couzinet 101. This new model differed from its predecessor in its tail section design, a new landing gear, and a powerplant consisting of three 75 hp Pobjoy R engines.
The Genesis of the Couzinet 101
The Couzinet 101 made its inaugural flight in June 1934. In the same year, the aircraft successfully completed its trials and underwent certification, receiving the registration number F-AMTJ. Throughout 1935, the aircraft undertook promotional flights, but it failed to attract customers.
Testing, Certification, and Spanish Service
In 1936, the sole Couzinet 101 was acquired by the Republican government of Spain. Despite its innovative features, the aircraft did not achieve commercial success during its initial marketing phase, leading to its eventual sale abroad.
Evolution: The Couzinet 103 and 110
Later versions of the aircraft included the Couzinet 103, equipped with 80 hp Salmson 9Adr engines, and the Couzinet 110. The Couzinet 110 was particularly notable, featuring three Salmson engines, each with 135 hp (101 kW), an enclosed cockpit for one or two crew members, and a separate passenger cabin for four people. However, much like their predecessors, these advanced versions also failed to achieve commercial success.
