Aircraft buyers routinely evaluate both original equipment manufacturer (OEM) parts and Parts Manufacturer Approval (PMA) components to satisfy ongoing maintenance and replacement requirements. While both categories are widely used across aviation applications, they often differ in areas like approval pathways, documentation practices, and typical price points. In this blog, we will present a detailed aircraft parts comparison by outlining the advantages commonly associated with OEM components, discussing the benefits of PMA products, and clarifying key distinctions between the two.

Integrated Drive Generators (IDGs) are critical components used across most modern aircraft electrical systems to provide the stable, high-frequency power required for essential onboard operations. Each unit achieves this stability by combining core generating hardware with speed-regulating elements in a compact, modular configuration, which is designed to maintain consistent electrical output regardless of changes in engine RPM. In this blog, we will explore how IDGs operate, what design features support their performance, and how they are applied across a range of aircraft platforms.

Anybody can appreciate the complexity of an aircraft, especially knowing that thousands of individual components work together to keep the airplane flying. Since modern airline travel is predicated on safety above all else, almost every aircraft system has a backup device in case of failure. One of the most indispensable but overlooked aircraft components is the Auxiliary Power Unit, or APU. In this blog, we will inform you on what an APU does and how it facilitates power and exhaust within jet aircraft.

Since automobiles have mostly shifted from manual transmissions to automatic transmissions, the mechanical clutch that enabled drive shafts and driven shafts to be connected has since been replaced with more advanced technology. The torque converter is the equipment piece that replaced the clutch, coming in the form of a fluid coupling that directs rotating power from the internal combustion engine to a rotating driven load. With the use of such equipment, automobiles can now stop and speed up on demand with the press of pedals, making complex operations seem fairly simple. To fully understand how the torque converter revolutionized how automobiles and other applications function, we will discuss their design and operations.
