An Auxiliary Power Unit (APU) functions as a supplementary power source for the machine it is mounted on. In larger aircraft, such as commercial passenger jets, APUs serve multiple purposes. While their primary function is to start the main engines on the aircraft, they can also power the onboard lighting, cockpit avionics, and the interior heating and cooling systems. By utilizing an APU instead of the main engines, aircraft can save on fuel and maintenance costs associated with a more complex power plant.
We offer a wide selection of APUs and their corresponding parts. Whether you are searching for the top-selling APUs or parts 3840022-2, 3826125, 3822074-3, 3844011-1, 3826282-2, we can quickly source and ship the necessary components to you. As a result of our attention to detail, we have earned several awards and certificates, such as the FAA 0056B. We are confident that we can provide solutions that surpass those offered by other providers. Furthermore, we are fully equipped to handle any AOG requirements via our expedited shipping services.
