The Duncan Aviation /Garrett APU system interfaces with the aircraft’s electrical system and includes controls for operating, monitoring, and regulating the APU. As seldom as these systems fail, when they do, it can be confusing to determine which box is causing the problem.
As LITEF LCR-92/93 AHRS units become increasingly difficult and costly to support, legacy PC-12 operators need a practical way to address avionics obsolescence without a major flight deck upgrade. Archangel Systems’ FAA-approved replacement provides a current-generation solution designed to minimize installation time, aircraft modifications, and downtime.
Few business jets have had the staying power of the Dassault Falcon 900. More than 40 years after its first flight, the three-engine Falcon 900 remains a capable large-cabin business jet, thanks to decades of refinements to its engines, range, aerodynamics, and avionics. While the different 900 models may look similar on the ramp, their capabilities, maintenance needs, and market values can vary significantly. Understanding how each generation evolved—and what those changes mean for ownership—can help buyers make a more informed decision when considering a Falcon 900.
The first step to troubleshooting an inoperable NAV is to identify the NAV source the pilot was using at the time of the failure.

Ionization technology has been used in several industries for years. Watch this video learn how the system can work for your aircraft.
Grease alone is the number one defense against corrosion. Corrosion cannot be prevented, but the effects of it can be lessened and controlled if you are aggressive with your grease gun. The greasier the better.
Simply put, fuel starvation occurs when the available fuel is unable to reach the engines. Water, debris and microbes in aircraft fuel tanks clog fuel supply lines and filters and ultimately starve the engines of the necessary fuel.
Batteries deserve more credit in the successful operation of your aircraft. They are the first component to engage an aircraft’s electrical system and the last line of defense before everything shuts down in an emergency.
Time sometimes slips by faster than we realize. And while it does, components that are sitting on shelves as serviceable are aging.
