Military personnel holding MOS 68H (aircraft pneudraulics repairer) will use this manual as a general guide in the repair of pneumatic systems (using gases such as air) and of hydraulic systems (using liquids such as oil). The manual covers basic hydraulic principles and describes the hydraulic systems used in US Army aircraft. It discusses aircraft in general--not specific types of aircraft. For instructions on the repair of hydraulic systems on a particular aircraft, refer to the technical manual written for that aircraft. Additional general information about hydraulics can be found in TM 9-243, TM 55-1500-204-25/1, TB 55-1500-334-25, TB 750-103, and NAVPERS 10310-B.
