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.
Don't get grounded by confusing nose wheel vibrations! A true nose gear shimmy—that rapid, side-to-side oscillation—is a serious issue often linked to play in the torque links, requiring immediate mechanical attention. In contrast, a simple vertical shudder felt during taxi or initial climb is often just an easily corrected wheel imbalance. This quick guide details the key differences and the essential steps to accurately troubleshoot the condition, starting with a simple inspection of the nose gear scissors.
Is your aircraft compliant? Missing small inspections tied to STCs or life-limited parts can lead to costly downtime and mandatory replacements. Learn why detailed records research is essential.
Don't Let Your Spare Aircraft Batteries Go Flat! Keeping a stock of essential aircraft batteries is crucial for operational readiness, but did you know that improper storage can drastically cut their lifespan and capacity? While temperature affects performance in the air, the storage environment is key to minimizing self-discharge and maintenance needs. Discover how optimizing storage temperature—from the effects of higher heat to the benefits of cold storage—can save you money, extend battery life, and ensure your spares are ready to deliver maximum performance when you need them most.
Honeywell has issued two Category II Reliability Service Bulletins, TFE731-79-3070 R1 and TFE731-79-5120, for the installation of new instruction plate decals on oil tanks to help prevent oil over-servicing.
To continue conducting business, operators need to stay connected to their contacts on the ground while at any altitude, anywhere in the world. Here is a low-cost alternative.
We urge a thorough inspection of this specific area during all future maintenance, especially as part of a pre-purchase evaluation, to detect and address cracks early.
Not sure why the engine computer light begins to flash after several flights and the only fault you can see is fault code 237, ECTM Buffer Filled? Keep reading to learn more.
Many factors will cause a low or high oil pressure indication on TFE731 engines. One of the more common causes is a faulty Breather Pressurizing Valve (BPV).
The unit requires to be function tested every 1200 hours or 36 Months, whichever occurs first. However, we have often witnessed that these actuators do not make it between function tests.
