Curtiss Model 41 Lark

The Curtiss Model 41 Lark was a commercial biplane from Curtiss Aeroplane and Motor Company that pioneering airmail, airline and bush pilots flew in the 1920s. It was based on the Carrier Pigeon airmail plane and shared its longer-span lower wing, since all four wing panels were interchangeable. It was welded tube with fabric covering, carried a pilot and three passengers, and came with a Curtiss C-6, a Wright J-4 Whirlwind or a Wright-Hisso E engine; some were converted to floatplanes. A 200 hp Wright J-4 version tested for the Navy outperformed the Curtiss-engined model and became the basis of the Fledgling series. Operators included Patricia Airways, Florida Airways and Colonial Air Transport.
