The Couzinet 33 Biarritz is a French monoplane built by René Couzinet whose first flight took place in 1931. He participated in the Raid Paris Noumea 1932. It made its first flight in November 1931. He had 27 hours of flight at the time of the departure of the first flight from Paris to Noumea he was to accomplish on March 6, 1932.
The plane was not designed specifically for the raid and nothing was planned for tropical flights, the mechanic astutely realized in stages, ventilation systems and engine cooling.
