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.
Honeywell issued Service Bulletin AS907-72-9094 that calls for the replacement of the #4 carbon seal on the HTF7000/AS907 series engines. We can do this as an engine-only event in as little as 4 days.
Are your aircraft's RVSM operations fully compliant? While FAA requirements shifted away from standalone approved programs, configuration control and height-monitoring standards remain strictly enforced. Learn the key differences between Section 9 and Section 3 pathways and Duncan Aviation’s role in keeping you airworthy.
As business travel demands grow, many owners of piston twins begin looking at turboprops for greater range, payload, reliability, and operational flexibility. But moving to turbine power involves more than buying a larger aircraft. From maintenance planning and pilot training to operating costs and regulatory requirements, a successful transition depends on carefully matching the aircraft to the mission. This article examines the key benefits, tradeoffs, and considerations to help buyers determine whether a turboprop is the right next step for their operation.
Most overhaul delays don't start in the shop. They start with the logbooks when the serial number stamped on a part doesn't match the one listed in the maintenance logs. Reconstructing that paper trail can ground an aircraft for weeks and force you to replace parts that are actually totally fine. Here's a quick breakdown of where Chapter 5 records often fall through the cracks and how to resolve discrepancies before your aircraft goes down.
While the FAA encourages the TCAS 7.1 upgrade, strict ICAO and EASA mandates make it a necessity for international operators. Learn how Version 7.1 improves flight safety, impacts your flight plans, and what certification path your aircraft requires.
A stunning new paint job can transform an aircraft, but a non-compliant registration number will quickly ground it. Under 14 CFR Part 45, the FAA enforces strict geometric rules for your tail number. Before you finalize your custom livery, make sure your design meets these non-negotiable dimensions.
Tracing an intermittent component failure on a static test bench is a frustrating guessing game. Fortunately, you are already carrying the solution. Documenting a live squawk with your smartphone camera provides technicians with unmistakable visual evidence, eliminating vague diagnostic loops and ensuring the problem gets fixed right the first time.
Is radar spoking cluttering your cockpit display? Whether it's caused by high-altitude arcing, external interference, or a recent maintenance, tracking down the source can be tricky. Keep reading to learn the common causes of radar anomalies and the essential troubleshooting questions to help you isolate the issue fast.
Tight maintenance schedules shouldn't ground your avionics upgrades. While MROs prioritize large, multi-shop jobs, Duncan Aviation’s Satellite shops offer a flexible alternative. Read how our teams can efficiently handle everything from connectivity installations to critical flight deck upgrades without the long wait times.
When buying or selling a business aircraft, there’s a big difference between how a model looks on a spreadsheet and how it performs in everyday operations.
