Historical Note:

The Franklin Series 6 engines represent an important chapter in American aviation engine development. Franklin Aircraft Engines, founded in 1944 in Syracuse, New York, specialized in air-cooled horizontally-opposed engines for light aircraft. The Series 6 engines, including the 6A4 and 6V4 variants, were widely used in post-war general aviation aircraft throughout the 1940s-1960s. These reliable powerplants powered numerous training aircraft, light sport planes, and experimental homebuilts. Franklin's innovative design featured direct-drive configurations and efficient air cooling, making them popular choices for aircraft manufacturers seeking dependable, lightweight engines. Though Franklin ceased aircraft engine production in the 1970s, these engines remain in service today, making accurate technical documentation essential for continued airworthiness.
