STCs for the Aero Commander Model S2R Thrush
This STC is to install a geared 1340 Pratt and Whitney
engine to
replace a 1340 Pratt & Whitney direct drive engine. The geared engine
uses either the 3S40 counter-weight or a 23D40 hydromantic with Otter
blades.
This STC is for an outside air scoop to brings outside air to
the engine thus lowering the air temp going into the engine by at least
125 degrees. The air going to the engine goes from a negative to a
positive air flow. This leads to lower fuel consumption, lower oil
temperatures, and increased engine performance.
These STCs have also been approved by Transport Canada.
