Modern general aviation (GA) maintenance relies on sophisticated avionics systems for navigation, communication, and safety. When something goes wrong, it can ground your aircraft or compromise your confidence in the cockpit. At AJ Aviation Services, our FAA-certified mechanics and avionics specialists use proven diagnostic techniques to keep your systems performing as they should. Here are five of the most common avionics issues we encounter and how we resolve them.
1. Communication Radio Failures
The Problem: Pilots often experience weak transmissions, static, or complete radio silence. This can stem from faulty wiring, antenna issues, or equipment failures.
How We Fix It: We perform detailed troubleshooting, from antenna continuity checks to radio unit bench testing. Once the source is identified, we repair or replace the faulty components and test the system for clear, reliable transmissions.
2. Navigation System Errors
The Problem: GPS or VOR systems can give inaccurate position data or fail altogether, especially in older avionics setups.
How We Fix It: Our team inspects antennas, wiring harnesses, and signal pathways. We also verify software updates and recalibrate systems as needed, ensuring accurate navigation support during flight.
3. Intermittent Instrument Displays
The Problem: Flight instruments or multifunction displays flicker, lose power, or present erroneous data.
How We Fix It: We trace the issue back to potential electrical faults, grounding problems, or internal component failures. Repairs often involve securing loose connections, replacing defective units, or recalibrating instruments for accuracy.
4. Autopilot Malfunctions
The Problem: Pilots may notice their autopilot disengages unexpectedly, won’t track properly, or fails to hold altitude.
How We Fix It: We run diagnostic checks on servo motors, flight control connections, and software settings. If components are worn or outdated, we replace or upgrade them to restore autopilot reliability.
5. Electrical Power Supply Issues
The Problem: Avionics depend on stable electrical power. Problems with alternators, batteries, or circuit breakers can cause system-wide outages.
How We Fix It: Our troubleshooting includes load testing batteries, inspecting alternators, and evaluating wiring for wear or corrosion. Once identified, we repair or replace the affected components and verify system stability.
