0075 00TM 1-6625-724-13&P0075 00-8Figure 5. Forward/Aft Blade Tracker Bracket and UTD LocationPROCEDURE 4: AFT UTD INSTALLATIONa. If the flare dispenser will not be installed during the rotor smoothing operations, attach the aft UTD bracket(29724300) using MS35308-310 hardware on top three bolt locations of the dispenser. See figure 5.b. If mounting the UTD with the flare dispenser, replace the flare dispenser’s mounting bolts with the adapter kitscrews (MS35308-326). Place the bracket against the flare dispenser onto the top 3 bolts. Mount theassembly back on to the airframe.c. Attach the sun shield (29722100) by placing the sun shield over the UTD (29310700) sensor receiving lens.Then swing the locking arm under the body of the UTD, placing the UTD bolts through the arm. This will placethe arm between the UTD and bracket.d. Install the UTD (29310700) on the aft UTD bracket (29724300). Ensure that the arrow on the UTD body pointsin the direction of rotation.e. Attach 50-ft. UTD cable (29725500) to the breakout cable (29085700) connected to the DAU receptacle markedMULTI-CH.f. Install the 50-ft. UTD cable (29725500) and attach the cable with a small loop of slack to prevent unnecessarystrain on the UTD plug or cable potting and tie wrap the cable to the mounting bracket.g. Connect ground lug from cable (29725500) to the stud on the aft UTD bracket (29724300). h. Ensure that the tracker select switch on the front panel of the DAU is in the DAY position.NOTEThe following steps are to be followed if nighttimetracking is anticipated. If tracking is only to beperformed during the day, proceed to procedure 6.PROCEDURE 5: NIGHT TIME TRACKING INSTRUCTIONSa. Ensure that the tracker select switch on the DAU is in the NIGHT position.b. Ensure that UTD sunshields, if installed, are removed prior to flight.c. Ensure that the underside, trailing edge of all blades are as clean as possible. This is to ensure optimumadhesion of the reflective tape.d. Place a 6-ft. strip of reflective tape (10605000) on the bottom of the blade. The tape is applied on the trailingedge of the blade starting 6 inches inboard of the tab, and moving outboard. See figure 6. Do not follow thecontour of the tab.e. If verification of the tape placement and reflection quality is desired, it can be verified by holding a flashlightaligned with UTD and shining it at the rotating blades. Any misplaced tape or tape with reduced reflectivity willstand out.Note Sunshield installationP/N 29722100Install TrackerGroundSecure cable withreinforced tape
