[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 chances of a successful ditching.

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.

To compensate for this, the lower wing was replaced with one of inverse gull design, and the main undercarriage units were moved to their "low points" and provided with spats.

Levasseur then made one final attempt to sell the PL.10 design in the PL.108, which was generally similar to the PL.107s.
