1. Review AIRCRAFT TECHNICAL LOG and CABIN TECHNICAL LOG for reported discrepancies
(1) With the Flight deck door open, set Flight Deck Access System (FDAS) switch, on the door chime module to NORM, ensure keypad red LED is
on.
(2) Key in 123ENT, on the keypad, and ensure that a continuous tone is heard, red keypad LED goes out and amber LED illuminates.
(3) Ensure “AUTO-UNLK” light on the P5 panel is on.
(4) Select DENY on the P5 panel and release, ensure “AUTO-UNLK” light goes off, and that the amber LED on the keypad goes off, and the red LED comes on.
(5) Enter flight deck, close the door, ensure it cannot be pushed open, ensure that no further tones are heard for one minute.
(6) Select “UNLCKED” ensure a click is heard from the door solenoid, release the door switch.
(7) Rotate door handle and open the door, key in 123ENT and ensure that the following sequence occurs: a continuous tone is heard for 30 seconds with flashing “AUTO-UNLK” light. After tone, ensure door solenoid energizes for 5 seconds and green keypad LED is on. After 5 seconds green LED goes out and solenoid relaxes.
(8) Set Chime module FDAS switch to off, ensure lock fail light (P5) comes on.

33. SVC AMM 12-14-01-683-008-001 Zones: NRC NO YES, Number(s):
DRAIN THE POTABLE WATER SYSTEM WHEN AMBIENT TEMPERATURE FORECAST IS BELOW FREEZING CONDITION DURING NIGHT LAYOVER.
WARNING: IF THE POTABLE WATER SYSTEM IS NOT DRAINED OR IN NORMAL SERVICE A MINIMUM OF ONE TIME EACH THREE DAYS, THE GROWTH OF BACTERIA CAN OCCUR. IF BACTERIA GROWTH CONTINUES, AND YOU DRINK THE WATER, ILLNESS CAN OCCUR.
(1) Make sure the shutoff valves for the lavatories and galleys are open.
(2) Open the doors for the potable water service panel and for the potable water drain panel.
(3) Connect a drain line to each water drain connection.
(4) Move the handles for the WATER SYSTEM DRAIN VALVES to OPEN (one on each panel).
(5) Move the handle for the WATER TANK FILL VALVE to the OPEN POSITION. This will open the WATER TANK FILL VALVE.
(6) When all the water has drained from the potable water system move the handle for the WATER TANK FILL VALVE to the CLOSED position.
(7) Move the two handles for the WATER SYSTEM DRAIN VALVES to CLOSED.
(8) Disconnect the drain lines from the water drain connections.
(9) Close the doors for the potable water service panel and the forward potable water drain panel
(10) Open these circuit breakers and attach DO-NOT-CLOSE tags:
Number Name Panel 11U28 POT WATER PRESS P11 33H6 WATER SYS AIR CPRSR P33 34P10 WATER QTY/PRESS P34 36D6 or 36D7 or 36E7 WTR HTR LAV SYS 1 P36 37H7 or 37E7 WTR HTR LAV SYS 2 P37

34. GVI STG M40-10 14.B.3 Rev P or later Zones: 200 NRC NO YES, Number(s): GENERAL VISUAL INSPECTION AND SERVICING OF THE PHOTOLUMINSCENT ESCAPE PATH MARKING SYSTEM
Concern: The fuel spar valve actuator design can result in airplanes operating with a failed fuel spar valve actuator that is not reported. A latently failed fuel spar valve actuator could prevent fuel shutoff to an engine. In the event of certain engine fires, the potential exists for an engine fire to be uncontrollable. NOTE: In case aircraft is dispatched per MEL 28-40-02 perform option 2 Option 1: Operational check without engine operation. 1. Supply electrical power to the airplane using standard practices. 2. Make sure all fuel pump switches on the Overhead Panel are in the OFF position. 3. If the auxiliary power unit (APU) is running, open and collar the L FWD FUEL BOOST PUMP (C00372) circuit breaker on the Main Power Distribution Panel. 4. Make sure LEFT and RIGHT ENG FIRE switches on the Aft Aisle Stand are in the NORMAL (IN) position. 5. Make sure L and R ENG START Selector Switches on the Overhead Panel, are in the OFF position. 6. Do an operational check of the left engine fuel spar valve actuator.
a. Move L FUEL CONTROL switch on the quadrant control stand to the RUN position and wait approximately 10 seconds. NOTE: It is normal under this test condition for the ENG VALVE disagreement light on the quadrant control stand to stay illuminated. b. Move L FUEL CONTROL switch on the quadrant control stand to the CUTOFF position. c. Verify the left SPAR VALVE disagreement light on the quadrant control stand illuminates and then goes off. d. If the test fails (light fails to illuminate), before further flight, repair faults as required (refer to Boeing AMM 28-22-11).
7. Do an operational check of the right engine fuel spar valve actuator.
a. Move R FUEL CONTROL switch on the quadrant control stand to the RUN position and wait approximately 10 seconds once the FUEL CONTROL switch is in the RUN position. NOTE: It is normal under this test condition for the ENG VALVE disagreement light on the quadrant control stand to stay illuminated. b. Move R FUEL CONTROL switch on the quadrant control stand to the CUTOFF position. c. Verify the right SPAR VALVE disagreement light on the quadrant control stand illuminates and then goes off. d. If the test fails (light fails to illuminate), before further flight, repair faults as required (refer to Boeing AMM 28-22-11).
8. If the L FWD FUEL BOOST PUMP circuit breaker was collared in step 3, remove collar and close.
Option2: Perform an inspection of the fuel spar valve actuator position. NOTE: This inspection may be most useful whenever the SPAR VALVE light does not function properly. 1. Make sure the L FUEL CONTROL switch on the quadrant control stand is in the CUTOFF position. NOTE: It is not necessary to cycle the FUEL CONTROL switch to do this inspection. 2. Inspect the left engine fuel spar valve actuator located in the left rear spar. NOTE: The Fuel Spar Valve actuators are located behind main gear doors on the rear spar.
a. Verify the manual override handle on the engine fuel spar valve actuator is in the CLOSED position. b. Repair or replace any fuel spar valve actuator that is not in the CLOSED position (refer to Boeing AMM 28-22-11).
3. Make sure the R FUEL CONTROL switch on the quadrant control stand is in the CUTOFF position. NOTE: It is not necessary to cycle the FUEL CONTROL switch to do this inspection. 4. Inspect the right engine fuel spar valve actuator located in the right rear spar. NOTE: The Fuel Spar Valve actuators are located behind main gear doors on the rear spar.
a. Verify the manual override handle on the engine fuel spar valve actuator is in the CLOSED position. b. Repair or replace any fuel spar valve actuator that is not in the CLOSED position (refer to Boeing AMM 28-22-11).
