The Adam RA-15 Major was a French sporting plane developed and produced in the decade after World War II.

The RA-15 was developed in 1948 as a higher-powered successor to the Adam RA-14 Loisirs, utilising a number of refinements including a plywood-covered fuselage and an enlarged rudder.

It was a side-by-side two-seater with dual controls, wooden construction and a fabric-covered two-spar wing which folded for storage in hangars.

The Major was designed to use any flat-four engine in the 65-75 h.p.

[1] A small series of Majors was produced in the late 1940s and early 1950s.
