Functional group code 06 corresponds to which aircraft system?

• A. Drive system
• B. Electrical system
• C. Hydraulic system
• D. Propulsion system

Answer: (A)

Functional group codes organize maintenance tasks by the system they belong to. Code 06 is assigned to the Drive system, which covers the mechanical parts that transmit power and motion—things like drive shafts, gears, gearboxes, and other linkages that cause actuators or mechanisms to move. This is the section you’d consult for components that physically drive motion, not for electrical power and wiring (electrical system), fluid-powered actuators (hydraulic system), or the engines and propellers themselves (propulsion system). So, code 06 points you to the Drive system because it specifically houses the mechanical transmission elements that enable movement.
