Figure 5. Forward/Aft Blade Tracker Bracket and UTD Location
PROCEDURE 4: AFT UTD INSTALLATION
a. 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 dispensers mounting bolts with the adapter kit
screws (MS35308-326). Place the bracket against the flare dispenser onto the top 3 bolts. Mount the
assembly 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 place
the 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 points
in the direction of rotation.
e. Attach 50-ft. UTD cable (29725500) to the breakout cable (29085700) connected to the DAU receptacle marked
f. Install the 50-ft. UTD cable (29725500) and attach the cable with a small loop of slack to prevent unnecessary
strain 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.
The following steps are to be followed if nighttime
tracking is anticipated. If tracking is only to be
performed during the day, proceed to procedure 6.
PROCEDURE 5: NIGHT TIME TRACKING INSTRUCTIONS
a. 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 optimum
adhesion 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 trailing
edge of the blade starting 6 inches inboard of the tab, and moving outboard. See figure 6. Do not follow the
contour of the tab.
e. If verification of the tape placement and reflection quality is desired, it can be verified by holding a flashlight
aligned with UTD and shining it at the rotating blades. Any misplaced tape or tape with reduced reflectivity will
