The Lorraine-Hanriot SGA 41 was a French aircraft built bt Lorraine-Hanriot in 1930 to compete for the Michelin Cup long-distance flying competition, which it won in 1931 and 1932.

Design
The SGA 41 was a low-wing monoplane with a fixed undercarriage powered by a 230 hp Lorraine Algol Junior air-cooled radial engine: the rules of the Michelin competition then in force restricted the power of competing aircraft to 230 hp. The aircraft was first flown with the engine uncowled: later a townend ring was fitted and subsequently the engine was enclosed in a NACA cowling, The airframe was constructed of wood, the fuselage being a conventional box-girder faired to a rounded section with the rear part fabric covered and the front covered with duralumin sheeting. The pilot occupied an open cockpit, in front of which the windscreen was incorporated in an elongated fairing. The wings were built up around three spars and were covered with birch plywood and had a small parallel-chord centre-section, outboard of which the wings were symmetrically tapered. The tail surfaces were also covered with birch ply. The fixed undercarriage consisted of spatted wheels with oleo-pneumatic suspension carried on faired-over V-struts and a sprung tailskid.

Operational history
