The Curtiss Model 41 Lark was a commercial biplane manufactured by Curtiss Aeroplane and Motor Company that was used by pioneering airmail, airline and bush pilots in the 1920s.
Development
[edit]The biplane was based on the Curtiss Carrier Pigeon, a purpose-built aircraft for airmail operations. The Lark also had a longer-span lower wing, similar to the Carrier Pigeon. Some models were converted to floatplane configuration with a central mounted pontoon and wing-mounted floats.[1]
The biplane was made of welded tube with fabric covering. It was available with three engine choices, the Curtiss C-6, the Wright J-4 Whirlwind, and the Wright-Hisso E. All four wing panels were interchangeable, giving the aircraft its unusual longer lower wings.[2]
A 200 hp Wright J-4 variant was tested for the United States Navy. This installation proved superior in performance to the Curtiss engined model.[3] This version eventually became the basis for the Curtiss Fledgling series of aircraft.[4]
Operational history

Patrica Airways operated a Lark for early bushplane operations. The aircraft flew with floats in warm weather, and skis in the winter.[5] The aircraft was pressed into service as an early hearse once, with the cargo needing to be seated upside down in the open seat and secured with haywire.[6]
Florida Airways operated a Curtiss Lark Miss Tallahassee on its CAM-10 U.S. airmail route between Miami and Atlanta. The aircraft was bought to take the place of two lost Stout 2-AT Pullman aircraft that could not operate out of the poorly prepared airstrips.[7]
Colonial Air Transport owned a Curtiss Lark which was one of the first aircraft to be registered using the new Underwriters Laboratories all-letter system (1921 to 1923). This Lark, registered as N-AABC, was used on the CAM-1 U.S. airmail route.[8]
