    8200 - FLUID SYSTEMS MAINTENANCE FAMILY   

This job family includes occupations that involve repair, modification, assembly, and testing of fluid systems and fluid system components of aircraft, aircraft engines, missiles, and mobile and support equipment. These fluid systems store, supply, distribute, and move gases or liquids in regulated amounts primarily to produce power, transmit force, and pressurize, cool, and condition cabins. Typical of such devices and systems are pumps, governors, regulators, flow control valves, regular valves, air turbines, actuating or slave cylinders, and major accessories that are components of fuel and oil systems; landing gear, brake, flap, door, and other hydraulic actuating and shock absorbing systems; and oxygen, fire prevention, and other pneumatic systems. The most characteristic knowledge and skills required by the work are those of controlling leakage of fluid under pressure; controlling vibration and heating in high-speed turbine operation; and understanding the principles, schematics, and sensing mechanisms involved in regulating fluid flow. Work on instruments that contain pneumatic and hydraulic components should be coded to the instrument work family, 3300.

Throughout the following information, an asterisk (*) stands for series with a published standard and a double asterisk (**) stands for series with a published flysheet.

Occupations in this family are:

8255 Pneudraulic Systems Mechanic*

This occupation includes jobs involved in the maintenance, modification, and repair of hydraulic and/or pneumatic systems and components that actuate mechanisms or produce, control, and regulate fluid flow. The work requires: a knowledge of the physical principles governing the behavior of fluids (liquids and gases) as they pertain to hydraulic and pneumatic systems or components; knowledge of basic electrical and mechanical principles; the ability to use technical manuals and schematics to test for and isolate malfunctions in hydraulic and pneumatic systems or components; and the skill to effect modification, repairs, or the complete disassembly and overhaul of such devices.

8268 Aircraft Pneudraulic Systems Mechanic*

This occupation includes jobs involved in the maintenance, modification, and repair of hydraulic and pneumatic systems associated with aircraft. The work requires: a knowledge of the physical principles governing the behavior of fluids (liquids and gases) as they pertain to hydraulic and pneumatic systems and their components; knowledge of aircraft structures and the relationship of hydraulic and pneumatic systems to the structure and other aircraft systems; knowledge of basic electrical and mechanical principles; the ability to use technical manuals and schematics and to test for and isolate malfunctions in hydraulic and pneumatic systems; and the skill to effect modifications, repairs, or maintenance required.
