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.
Navigating the 2026 preowned jet market requires looking beyond simple asking prices. Competition remains fierce for premium long-range models. Meanwhile, supply chain bottlenecks and maintenance requirements are reshaping aircraft valuations across all categories, making real-time market intelligence and expert guidance critical for both buyers and sellers.
Proper maintenance of starter and generator terminal blocks is critical for aircraft safety and reliability. A seemingly small issue, such as a loose wire or incorrect torque, can cause catastrophic failure through arcing, rapidly leading to melting, component disintegration, and potential damage to the surrounding aircraft structure.
The term situational awareness is frequently used in aviation, but what does it actually mean for a pilot in the flight deck? And how can modern avionics, like the Garmin G600 TXi, take that awareness to the next level? Watch this video and learn.
Aircraft buyers and sellers often face a significant question: What exactly constitutes damage history, and how does it affect an aircraft's value? This question is more complex than it seems, as damage is a subjective concept with no universal standard. To shed light on this issue, we spoke with three sales representatives from Duncan Aviation's Aircraft Sales & Acquisitions: Ann Pollard, Tim Barber, and Doug Roth.
Now that the Gogo 5G network is complete, Gogo is focusing on updating customers’ service and experiences on their licensed 3G/4G network by upgrading to AVANCE L3 or AVANCE L5 connectivity platforms, the latest LTE network technology.
When overhauling a Vertical Gyro, most facilities stop at replacing the components mandated by the Component Maintenance Manual. While this meets the requirements for returning the gyro to service, Duncan Aviation goes further, prioritizing what is right over what is merely required.
Follow these steps to troubleshoot classic Learjet spoileron systems.
There is only ONE way to safely and legally ship pressurized containers like oxygen cylinders, fire bottles, emergency air bottles, reservoirs, and water bottles. Keep reading to learn what that is.
During a typical business aircraft transaction, the Purchase Agreement is what is referenced when deciding what constitutes a discrepancy and who is responsible for paying for it. However, it provides little direction on how to perform the repair.
Most inspection tasks on the Honeywell AS907 (HTF7000) are straightforward, offering consistent turntimes and cost expectations. However, it's important to note that the Borescope inspections of turbine and compressor components can reveal issues that may extend downtime and increase costs
Gust locks lock the control column in place, preventing random movement and possible damage of the surface from wind while an aircraft is parked. It only takes a small investment to prevent damage that could cost tens of thousands of dollars and hours to repair.
