The Model TSC-1A1 Teal amphibian has been developed
to provide extended range and increased useful load compared to the
Model TSC-1A. This has been done by adding 23 US gallon fuel tanks
to each wing leading edge between wing stations 36 - 72. These
tanks are located forward of the center of gravity. Increased
useful load capability has been provided by reviewing the airframe
structure to permit a gross weight of 2 200 pounds.
The 2 200 pound gross has been limited to land
operation; 2 100 pounds has been established as an upper gross limit for
water operation to provide satisfactory performance characteristics as
regards take off run and climb out of water areas surrounded by steep
banks and hills. These new gross weights exceed Model TSC-1A
limits by 300 and 200 pounds respectively.
As a further option, the 24.5 US gal hull fuel tank
may be retained with the wing tanks to provide a usable fuel capacity of
65 US gallons for longer range.
