As an Avionics Technician you install, test, inspect and maintain the electrical and electronic systems that keep aircraft safe and airworthy, including navigation, communication and flight control systems. Your day-to-day work involves reading engineering drawings and technical manuals, diagnosing faults using specialist test equipment, and carrying out repair or replacement work on aircraft systems. You work closely with aircraft maintenance engineers, quality assurance inspectors and airline operations teams to ensure all work meets strict regulatory standards set by the European Union Aviation Safety Agency (EASA). Avionics Technicians are typically based in maintenance, repair and overhaul (MRO) facilities, airline hangars or at airports, with shift work common in operational environments.
Listen: a day as an Avionics Technician
You arrive at the hangar at 06:30, badge through security and change into your overalls. The morning begins with a shift handover briefing from the night team. A supervisor runs through the status of three aircraft currently in for scheduled maintenance at the MRO facility. You are assigned to a narrow-body jet that has been flagged for an intermittent fault on its VHF communications radio — one of the systems aircraft must have fully operational before it can fly. You collect the aircraft's technical log and locate the relevant section in the approved maintenance manual, which you access on a tablet loaded with the operator's controlled documentation system. You work through the fault-isolation procedure methodically, connecting a specialist avionics test set to the radio rack in the electronics bay beneath the cockpit. The fault does not show up immediately, so you spend the best part of ninety minutes running checks and swapping out line-replaceable units before isolating a faulty connector.
A strong Leaving Certificate with passes in Mathematics, Physics and Technical Drawing is advantageous for entry into avionics programmes. The typical Irish route is a QQI Level 6 Advanced Certificate in Avionics or Aircraft Maintenance, offered through providers such as TU Dublin or Shannon College of Hotel Management's aviation partners, or via the SOLAS-approved aircraft maintenance apprenticeship. From there, technicians work towards an EASA Part-66 Category B2 Aircraft Maintenance Licence (Avionics), which is the essential industry authorisation required to certify maintenance work on aircraft electrical and electronic systems. Some technicians progress to an NFQ Level 7 or Level 8 degree in Aerospace Engineering or Electronic Engineering through institutes such as TU Dublin or the University of Limerick, which can open further career avenues. Continuous professional development and type-rating courses on specific aircraft are a normal part of the career.
Most Avionics Technicians begin their career as apprentice or trainee technicians, working under supervision in an MRO facility or airline maintenance base while completing their EASA Part-66 B2 licence. Once licensed, you take on independent maintenance and certification tasks, and may specialise in particular aircraft types or systems such as avionics integration or flight management systems. With experience, senior technicians can progress to team leader, quality assurance inspector or technical training roles within an MRO or airline. Further academic study or management qualifications can lead into engineering management, continuing airworthiness management or regulatory roles with the Irish Aviation Authority (IAA).
AI-assisted diagnostic tools are increasingly being introduced in MRO environments, helping Avionics Technicians pinpoint faults more quickly by analysing large volumes of aircraft health monitoring data. Predictive maintenance systems powered by AI are shifting some routine inspection work from scheduled to condition-based maintenance, changing how workloads are planned. However, the hands-on work of physical installation, repair and certification remains firmly human, as regulatory frameworks require qualified technicians to personally verify and sign off on all aircraft maintenance. Overall, AI is likely to enhance rather than replace the role, making technicians more efficient and better informed.
