2. Internal Leak Check for the Rudder Power Control Unit (Procedure 6)
A. General
(1) Use this procedure to find the internal leakage of the rudder power control unit for hydraulic system A or B.
B. Reference
(1)
AMM 24-22-0/201, Manual Control
(2)

D. Prepare for the Main Rudder PCU Internal Leakage Check
(1)
Make sure this circuit breaker is closed:
(a) P6-2, Circuit Breaker Panel:
1) RUDDER LOAD LIMITER
(2)
Open the access door 9510.
(3)
Remove the access panels 9512 and 9514 from the vertical fin.
(4)
Do this task: Supply electrical power (AMM 24-22-0/201).
WARNING: MAKE SURE THET PERSON AND EQUIPMENT ARE CLEAR OF ALL CONTROL SURFACES BEFORE YOU SUPPLY HYDRAULIC POWER. AILERONS, RUDDERS, ELEVATORS, FLAPS, SLATS, SPOILERS, LANDING GEAR, AND THRUST REVERSERS CAN MOVE QUICKLY WHEN YOU SUPPLY HYDRAULIC POWER. THIS CAN CAUSE INJURY TO PERSONS OR DAMAGE EQUIPMENT.
(5)
Do this task: "Rudder Hydraulic System A and B Pressurization" (AMM 27-21-0/201).
(6)
Put the FLT CONTROL A and B switches, on the P5-3 panel, to the ON position.
(7)
Move the rudder pedals through 5 cycles of full travel.
(a) Move the rudder pedals until the rudder is in approximate center position.
(8)
Open the Electronic Equipment Access Door, 1201 to gain access to the main electronics equipment compartment.
(9)
Use a digital voltmeter to verify 4.38 Vdc to 5.62 Vdc between pin 1 and pin 2 of connector D10070 on the E2 shelf (stanchion station 351) in the EE bay.
(10)
Verify that the STBY RUD ON Light on the overhead panel P5-3 is not illuminated.
(11)
Put the FLT CONTROL A switch, on the P5-3 panel, to the OFF position.

E. Rudder Main PCU System B Internal Leakage Check in the Extend Direction
NOTE: You will need 3 persons to complete this task.
There is a time limit to complete some of the steps in this task.
(1) Use the Yaw Damper Coupler (YDC) to command the Rudder Pressure Reducer to the "Low" pressure state:
(a)
Push the ON/OFF key on the BITE keypad on the face of the yaw damper coupler located on the E1-3 shelf. 1) Make sure that the display shows ENTER BITE?
