Which rating is responsible for maintaining aircraft electrical systems?

The rating responsible for maintaining aircraft electrical systems is Aviation Electrician's Mate, abbreviated as AE. This role specifically focuses on the electrical components of aircraft, including the installation, maintenance, troubleshooting, and repair of electrical systems. AEs are trained extensively in understanding electrical theory, electrical wiring, power distribution, and adherence to safety practices to ensure the reliable operation of aircraft systems.

While the other ratings have important roles in aviation maintenance, they do not primarily focus on electrical systems. Aviation Machinist’s Mates (AD) specialize in aircraft engines, Aviation Structural Mechanics (AM) work on airframe structures, and Aviation Electronics Technicians (AT) focus on electronics but are more concerned with navigation, radar, and communication systems rather than the broader scope of electrical systems. Thus, the AE rating is uniquely positioned to handle all matters relating to an aircraft's electrical systems, which is why it is the correct answer.
