CHAPTER 12 LANDING GEAR, BRAKES, AND HYDRAULIC UTILITY SYSTEMS Chapter Objective: Upon completion of this chapter, you will have a working knowledge of the maintenance required for the aircraft landing gear and brakes. You will have a working knowledge of the hydraulic utility systems, such as nose gear steering, catapult, arresting gear, skid control systems, and other related systems. Maintenance on the landing gear and brakes, at times, requires maintenance of related systems. In this chapter, we will discuss the general landing gear systems and brake systems first, and then we will discuss various hydraulic utility systems. We will also examine drop checking procedures, troubleshooting, and the alignment and adjustment of the landing gear. The systems discussed in the following paragraphs are representative. For training purposes, we will use many values for tolerances and pressures to illustrate normal operating conditions. When actually performing the maintenance procedures discussed, you must consult the current applicable technical publications for the exact values to be used. LANDING GEAR SYSTEMS Learning Objective: Identify the various types of landing gear systems used on fixed-wing and rotary-wing aircraft. Every aircraft maintained in today’s Navy is equipped with a landing gear system. Most Navy aircraft also use arresting and catapult gear. The landing gear is that portion of the aircraft that supports the weight of the aircraft while it is on the ground. The landing gear contains components that are necessary for taking off and landing the aircraft safely. Some of these com- ponents are landing gear struts that absorb landing and taxiing shocks; brakes that are used to stop and, in some cases, steer the aircraft; nosewheel steering for steering the aircraft; and in some cases, nose catapult com- ponents that provide the aircraft with carrier deck takeoff capabilities. FIXED-WING AIRCRAFT Landing gear systems in fixed-wing aircraft are similar in design. Most aircraft are equipped with the tricycle-type retractable landing gear. Some types of landing gear are actuated in different sequences and directions, but practically all are hydraulically operated and electrically controlled. With a knowledge of basic hydraulics and familiarity with the operation of actuating system components, you should be able to understand the operational and troubleshooting procedures for landing gear systems. Main Landing Gear The typical aircraft landing gear assembly consists of two main landing gears and one steerable nose landing gear. As you can see in figure 12-1, a main gear Figure 12-1.–Tricycle landing gear. 12-1
