Levasseur PL.10

The Levasseur PL.10 was a carrier-based reconnaissance aircraft developed in France in the late 1920s.[1] It was a conventional, single-bay biplane along similar lines to Levasseur's contemporary designs for the French navy, including a watertight, boat-shaped fuselage, small underwing floats, and undercarriage that could be jettisoned in flight in order to improve the changes of a successful ditching.

Levasseur PL.10 in flight

Levasseur PL.101

Thirty of these machines were purchased by the Aéronavale, entering service aboard the carrier Béarn in 1931 under the designation R3b.[2] In 1935, these were followed by thirty examples of an improved version, the PL.101, which replaced the original PL.10s in service aboard the carrier.[1]

The PL.10 also radically revised in the PL.107 torpedo bomber prototypes of 1937. These featured a fully enclosed cockpit that also enclosed the mounting between the fuselage and upper wing, therefore moving the fuselage higher in the interplane gap. To compensate for this, the lower wing was replaced with one of inverse gull design, and the main undercarriage units were moved to its "low points" and provided with spats. Two prototypes were evaluated and rejected by the Aéronavale. Levasseur then made one final attempt to sell the PL.10 design in the PL.108, which was generally similar to the PL.107s. This first flew on 26 September 1939, but proved no more promising than its predecessors.
