Necessity truly is the mother of invention! In 1989 Floyd Jones, founder of F&M Enterprises, was changing the oil and cleaning the oil screen on his Cessna 150 Aerobat. While cleaning the mess made by the removal of the oil screen Floyd had an idea. His idea... an adapter that would bolt directly to the engine and provide a method for using a spin-on filter. Since its inception, the idea of an engine mounted oil filter was an instant success. Through the years, F&M Enterprises has received numerous requests to design aircraft engine mounted oil filter adapters that would accommodate everything from the small C-75 to the larger IO-520 engines. Today, F&M Enterprises manufactures five different adapters that allow aircraft owners an opportunity to lower the cost of routine maintenance, extend engine life, and provide an extra margin of safety.
