The Weatherly Aviation Company was formed by John C Weatherly and the company began by converting examples of the Fairchild M-62 Cornell for agricultural duties as the Weatherly WM-62C (19 built). The Weatherly 201 (2 built) was developed from the WM-62C and the type entered production in 1968 as the Weatherly 201A (5 built) powered by a 450hp Pratt & Whitney and with a maximum take-off weight of 4800lb(2179kg). The Weatherly 201B (45 built) entered production in 1971 and featured a number of small improvements and was followed by the Weatherly 201C (38 built) which entered production in1975 which had further small improvements made. The Weatherly 620 series are generally similar but have a greater maximum take-off weight. The Model 620 entered production in 1979 and was followed by the Model 620A in 1989 which has greater fuel capacity. The Model 620B is 4" longer than the previous models. One example of the Model 620TP has been flown powered by a 500shp(373kW) P&W turboprop. A large number of Weatherlys are active in South America.
