TheConsolidated Model 17 Fleetsterwas a 1920sAmericanlight transportmonoplaneaircraft built by theConsolidated Aircraft Corporation.^[2]There was several closely related types the Model 17, Model 18, Model 20; then the C-11, C-22, and XBY military versions.

Design and development[edit]

The Fleetster received ApprovedType CertificateNumber 369 on 29 September 1930.^[3]It was designed to meet a requirement of theNew York, Rio, and Buenos Aires Line(NYRBA) for an aircraft to serve the coastal routes in South America. The Fleetster had a streamlined all-metalmonocoque fuselagewith a wooden wing. Thepowerplantwas a 575 hp (429 kW)Pratt & Whitney R-1860 Hornet B radial engine.It was available as a landplane or seaplane and could accommodate up to eight passengers, although the three NYRBA aircraft were fitted with two full-width seats each for three passengers.

Aparasol-wingversion (theModel 20 Fleetster) was also developed with the wing supported by four short struts. The open cockpit was moved behind the passenger cabin and the resultant space was used as a cargo compartment. Three aircraft were built for NYRBA and a privateCanadiancustomer.

In 1932 a carrier-borne dive bomber version (Model 18) was evaluated by theUnited States Navyas theXBY-1,it was not ordered but was the firststressed-skinaircraft, and the first aircraft with so-called "wet wing"integral fuel tanks in the wings operated by the Navy.
