The Aircraft Electronics Association is asking the Bureau of Labor & Statistics to reject a June 4 proposal by various aviation industry groups to remove "Avionics Technician" from the government's database of existing occupations. The Standard Occupational Classification (SOC) system is used by federal statistical agencies to classify workers into occupational categories for the purpose of collecting, calculating or disseminating data. All workers are classified into one of 840 detailed occupations according to their occupational definition. For decades, the information provided by the SOC has been widely used for career recruiting throughout the industry. The proposal aims to replace the vague existing category "Aircraft Mechanics and Technicians" with three separate occupations—certificated mechanics, certificated repairmen and non-certificated technicians—to more accurately represent and differentiate between real-world maintenance jobs in the industry. However, as part of the proposal, the Aviation Technician Education Council (ATEC) and other groups are asking the BLS to re-classify "49-2091 Avionics Technician" as a certification. The AEA, which states that it "represents tens of thousands of avionics technicians working under the certification of an FAA Part 145 repair station", opposes the move, believing that avionics technicians should remain a distinct occupation.
