secured within an outer steel frame. The frame is both welded and bolted to the flight deck inboard of each of the deck sheaves at an approximate 45 degrees forward facing angle. The bolted section of the frame is removable in order to replace worn impact pads as needed. Upon initial arrestment by an aircraft the terminal will impact on the pads instead of the steel deck, minimizing damage to the fittings, purchase cable, and crossdeck pendants. Wire Supports The wire supports provide a method of raising the crossdeck pendant off the flight deck to ensure arresting (tail) hook engagement of the incoming aircraft. These wire supports are actually preshaped leaf springs that are designed to maintain a crossdeck pendant height of 2 inches minimum, measured from the bottom of the pendant to deck at its lowest point, and 5 1/2 inches maximum, measured from the top of the pendant to the deck at its highest point (fig. 3-30). The crossdeck pendant height is regulated by adjusting the wire support’s contour height. Each wire support is mounted directly to the flight deck. The forward end of the wire support spring is rigidly secured by use of a cam mounted in a deck recess and a follower and pin at the end of the wire support. The forward end of the spring is then held in the deck recess by the cam-end disc and the cam-end forward stop (fig. 3-31). Adjustment of the wire support spring height is made at its aft end. The aft end of the wire support is also pinned, and set between adjustable forward stops as required (fig. 3-31). Wire supports are replaced when they become deformed or damaged or when they fail to maintain the required crossdeck pendant height of 2 inches Figure 3-30.—Checking crossdeck pendant height. 3-34
