Bendix Magnetos earned their notoriety and popularity due to their significant production during World War II from the Bendix factory in Sidney, NY. The growth of Bendix Magnetos and all other types of magnetos owe their success to Robert Bosch. Bosch was the first person able to adapt a magneto to an automotive engine. After this innovation in 1897, magneto use proliferated and allowed for the expansion of aviation in the 1920s and 1930s. The Scintilla Magneto Company, a Swiss company, started a manufacturing plant in Sidney, NY after World War I ended. The extensive use of magnetos in America led to Bendix Aviation Corporation purchasing Scintilla Magneto Company in 1929. The production of the Bendix Magnetos was expanded in 1935 and would continue until the end of World War II. By 1942, the labor force at the Bendix Magneto plant had risen from 600 to 4,000 workers. Near the…

"I need to check the 'drop' on my dual magneto. Can you provide some easy instructions?" Lycoming engine operators should be aware of Lycoming Service Instruction 1132B, issued June 18, 2010, which provides a procedure to use if magneto drop exceeds 175 RPM during the pre-flight check.   A basic magneto drop-off check based on engine speed is typically done during the before-takeoff check to determine the loss of engine speed that occurs when magnetos are switched from both magnetos to one (left or right) magneto. The maximum drop-off limit is in the Pilot's Operating Handbook (POH).   Although this basic drop-off check, based on just engine speed, is satisfactory under most normal conditions, it does not take into account unusual circumstances of temperature, humidity and engine wear.   If the RPM drop exceeds 175 RPM, set the throttle to obtain 1,800 RPM. Slowly lean the mixture until the RPM…

A dual magneto is an aircraft magneto that incorporates a single drive source powering two magnetos. This makes for an arrangement in which the left and right magnetos are contained in a single housing and operated by a single magnet rotor and engine drive. A dual magneto is a convenient solution for most aircraft owners, as aircraft magnetos are almost always used in pairs, and dual magnetos contain just that.   Quality Aircraft Accessories offers a great selection of dual magnetos as well as other reputable models such as the Slick magneto and Bendix magneto.

Here at Quality Aircraft Accessories, we specialize in aircraft magnetos and aircraft magneto service. We take pride in our wide breadth of knowledge surrounding aircraft parts and thought we'd share some of that expertise to provide a better understanding of just what an aircraft magneto is and how one works.   An aircraft magneto is an engine driven electrical generator that uses permanent magnets and coils to produce high voltage to fire the aircraft spark plugs. Aircraft magnetos are used in piston aircraft engines and known for their simplicity and reliability. Often sold in pairs, or as a dual magneto, this compact device requires no external electrical source to operate.   You can learn more about a dual magneto by clicking here.   Here's how an aircraft magneto works. Aircraft piston engines are designed with two independent ignition systems. This is made up of two aircraft spark plugs per cylinder…
