Figure 7. Pilot Heel Vertical Accelerometer Mounting Plate (P/N 29317300)
Install washers (MS15795-810) between accelerometer and mounting plate and install accelerometer
(28110900). Use enough washers to prevent accelerometer from extending beyond plate into floor.
Connect accelerometer cable (29105600) from accelerometer (PHV) to the DAU receptacle marked ACC3.
If tail rotor balancing is to be performed, the tail rotor balancing equipment may be installed (task 6, procedures
1 through 3) at this time. If not, proceed to procedure 5.
PROCEDURE 5: NIGHT TIME TRACKING INSTRUCTIONS
The following steps are to be taken if nighttime tracking
is anticipated. If no flights will be performed after dusk,
proceed to procedure 6.
Ensure that the TRACKER MODE switch is in the NIGHT position.
Ensure that the underside, trailing edge of all blades is as clean as possible. This is necessary for optimum
adhesion of the reflective tape.
Place a single, 5-ft strip of reflective tape on the underside, trailing edge of each blade as shown on figure 8.
The tape should begin 18 inches before the hub-end edge of the trim tab, and proceed toward the blade tip.
Do not follow the contour of the tab. Ensure that the tape is smooth and as straight as possible.
If verification of the tape placement is desired, it can be viewed by holding a flashlight near your head and
shining it at the rotating blades. Any misplaced sections of the tape will stand out.
