Hartzell Engine Technologies has started an informational series regarding their products. The first entry in the series is a video entitled “Understanding Your Aircraft Starter’s Duty Cycle”. The video is a little over three minutes long and provides information of the duty cycle of different starters. The information provided is great and should be used by all pilots. However, if you are like me you would like to know what is happening in the starter when these guidelines are not followed. The results of overheating your starter will definitely lead to frustration and the purchase of a new starter.The first thing to know about aircraft starters or starters in general is that they are very powerful components of your ignition system. The electric motors...

Turbocharger Cool Down

by Seth Black

Hartzell Engine technologies has produced a second video in their educational series highlighting their product line. The second installment is titled "The Importance of Cool Down Time for Your Aircraft's Turbocharger". The video details the effects of cutting short your cool down time. Hartzell also goes into proper procedures for cool down to prevent these effects. We highly recommend watching the below video if you are needing information about cool down times as this extends the life of your turbocharger.     The video does not fully illustrate the effects of a shortened cool down for a turbocharger. According to our experienced turbocharger technician, J.R. Hargrove, the more damaging stress of short cool down will occur in the turbine housing of the turbocharger. When the part is not allowed proper...

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...

Overhaul and Rebuild are terms commonly used in Aviation to refer to the condition of a part. People in the Aviation industry often use these words interchangeably; it is easy to see the parts as the same and generally the overhaul is less expensive. Often people are left asking, “why should I get a Rebuilt unit when an overhauled is the same for less?”. The two terms are different because of the type of work performed. An Overhaul means that a part is disassembled and examined, parts are replaced as necessary according to the manufacturer’s overhaul manual. To consider a part in Rebuilt condition it must be brought back to factory new specifications as per the manufacturer. Contrasting the two definitions highlights the disparity between Rebuilt and Overhauled. The differences between a Rebuilt and Overhauled...

Magneto failure is uncomfortably commonplace. Mags are full of plastic components that are less than robust; plastic is used because it’s non-conductive. Fortunately, our aircraft engines are equipped with dual magnetos for redundancy, and the probability of both magnetos failing simultaneously is extremely remote. Mag checks during preflight runup can detect gross ignition system failures, but in-flight mag checks are far better at detecting subtle or incipient failures. Digital engine monitors can reliably detect ignition system malfunctions in real time if the pilot is trained to interpret the data. Magnetos should religiously be disassembled, inspected and serviced every 500 hours; doing so drastically reduces the likelihood of an in-flight magneto failure. Written by: Mike Busch

Turbocharging Systems While turbocharging systems are used in many applications from automotive to marine, they were first developed for aviation –with experimental installations beginning in the 1920’s. The function of an aircraft turbocharging system is to maintain desired manifold pressure at a given throttle setting, regardless of varying conditions or ambient air pressure. This is obtained by a turbocharging system, generally consisting of a turbocharger, a bypass valve and one or more controllers. As a fail-safe feature, many applications also include a pressure relief valve that can avert a total control failure or cold start overboost. A turbocharger operates by taking engine exhaust gas and diverting it through a turbine. Exhaust gas pressure and heat energy extracted from the gas will cause the turbine wheel to rotate the compressor wheel. Rotation of the compressor wheel takes ambient air, draws it into the compressor housing where it is...

"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...
