The avionics technician diagnoses discrepancies across aircraft electrical, avionics, and mission-system installations, documents work performed accurately, and coordinates with engineering, quality, and maintenance personnel to ensure all work meets approved technical data, customer requirements, and FAA regulatory and repair-station procedures. Specialized technical execution is delivered by the Aircraft Integration Centre (AIC), a Part 145 facility focused on airframe modification, and Aerospace Design (ASD), which provides organic design engineering and FAA-authorized certification.
