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.
As condensation collects on the windshield of our aircraft, it has to drip somewhere. And that somewhere is directly on this units below.
As the pre-owned aircraft market stabilizes, the Bombardier Global Express XRS has solidified its status as the top-tier value choice for ultra-long-range travel. Offering intercontinental reach and a proven platform at a significant discount compared to newer models, the XRS represents a strategic entry point for value-conscious operators. The following analysis breaks down the current pricing trends, critical value drivers, and the competitive landscape for this enduring market leader.
The precision of an aircraft’s Environmental Control System depends on small, often-overlooked temperature sensors. These units act as miniature vacuums, drawing in cabin air, along with dust and debris, to provide the real-time data necessary for passenger comfort. This article explores why regular cleaning and maintenance of these sensors is critical to ensuring the ECS delivers the precise climate control it was engineered to provide.
It’s a common question that many operators hesitate to ask, but the answer is a definitive no. In reality, regular gas-path cleaning is a vital pillar of preventive maintenance, especially for aircraft operating in salt air or polluted environments. A strategic wash schedule is your best defense against performance loss and the high cost of corrosion.
Affecting 600+ aircraft, these Learjet aileron Service Bulletins require specialized NDT inspections and structural modifications. Duncan Aviation’s experts break down the requirements, downtime expectations, and why choosing the right facility is vital.
Unscheduled avionics squawks are an operational nightmare, often grounding your aircraft at the worst possible moment. The challenge isn't just the repair—it's the downtime spent guessing if the fault lies in the unit or the airframe. Duncan Aviation’s Loaner Program solves this by providing immediate cross-diagnostic units, letting you verify the fix and return to service while your original hardware is on our bench.
For companies purchasing a business aircraft for the first time, the process often reveals a steep learning curve. While selecting an airplane can feel like the primary decision, acquisition specialists say the more critical factor is how well buyers understand the transaction before they ever make an offer.
Accurate airborne weather radar is a critical component of flight safety and operational efficiency. Convective activity, turbulence, hail, lightning, and windshear pose ongoing operational challenges, often resulting in delays, reroutes, structural damage, and increased maintenance costs. Advances in predictive radar technology are intended to improve detection accuracy, reduce crew workload, and enhance situational awareness in these environments.
Business aircraft operators with older audio systems often face challenges maintaining reliable communication and audio quality in the cockpit and cabin. For aircraft equipped with legacy Baker 1045 audio panels, the PS Engineering PAC37 offers a modern, plug-and-play replacement with enhanced flexibility and features.
There should never be a time during installation, testing, or adjustment when the potentiometer rods on the actuator are adjusted.
