SBF100-28-052 Jun 15/09 Page 2 C. Reason

(1) On an aircraft equipped with an Integral Center Wing Tank (ICWT) and the automatic center tank fuel transfer syst em selected in the automatic mode, the center tank pumps will switch off automatically without indications on the flight deck when the center tank is empty.

(2) However when Service Bulletin SBF100-31-067 (issued in January 2008) is incorporated, a ”CTR TK PUMP 1 and 2” alert will be presented on the Multi function Display (MFDU) and the FAULT indication will appear for both center tank fuel transfer pumps on the fuel control panel when the center tank is empty. The operational procedure associated with this alert instructs the crew to switch the center tank pumps off. These fault indications have resulted in pilot reports and unnecessary maintenance follow up.

(3) Only a limited number of ICWT equipped aircraft are still equipped with the automatic center tank fuel transfer syst em. Modification of the automatic center tank fuel transfer system into the semi-aut omatic center tank fuel transfer system will prevent the unnecessary maintenance follow up. This Service Bulletin contains the instructions for that modification.

D. Description

(1) This Service Bulletin is divided into 3 parts as follows:

Part 1 : The modification of the Center Wing Tank Fuel Transfer Logic. This part tells you how to: - Remove the Fuel Control Panel and replace the connector - Remove the Combined Processor Totalizer and replace the connector

- Perform the inspection for the presence of the “autofeed fault enable” wire

- Install the Combined Processor Totalizer and the Fuel Control Panel

- Perform the operational test of the fuel control panel, the BITE test of the Combined Processor Totalizer and the operational test of the fuel transfer pumps.

- Perform the verification of the CENTER TANK Program Pin on both MFDU’s.

Part 2 : The rework of the wiring for MFDU 1 and MFDU 2. This part tells you how to:

- Remove both MFDU’s

- Rework the wiring for the MFDU’s

- Install the MFDU’s

- Do the after installation test of both MFDU’s.

NOTE : Part 2 of this Service Bulletin is only applicable when the verification in accordance with Part 1 of this Service Bulletin reveals that the CENTER TANK discrete input shows “ICW”.

7. Job Set-Up

A. Do a check of the fuel tank contents (1) Open the access door(s) 178BR. (2) On the Fueling Control Panel (FCP), open the safety guard and set the POWER switch to ON. (3) On the FSP, make sure: - The CENTRE - OVERFLOW VALVES OPEN light comes on - The CENTRE tank display shows a minimum of 400 kg (880 lb) of fuel - The LH and RH MAIN tank displays show approximately, but no more than 3300 kg (7250 lb) of fuel.

NOTE : If the CENTRE - OVERFLOW VALVES OPEN light does not come on, one or both overflow valves are not completely open. Set the POWER switch to OFF and then to ON again to open both overflow valves.

NOTE : There must be enough fuel in the center tank to fill each main tank to at least 3500 kg (7720 lb).

(4) If necessary, adjust the fuel quantity in the tanks, refer to 12-11-01-650-823 for corrective action. (5) On the FCP, set the POWER switch to OFF and close the safety guard.

NOTE : If one or both center-wing tank overflow-valves is (are) not closed the power will not go off. Set the POWER switch to ON and wait for a moment. Then set the POWER switch to OFF again to close the overflow valve(s).

SUBTASK 28-16-00-860-045-B00 C. On the multifunction control panel turn the brightness control knobs clockwise to switch the MFDU on.

Procedure

A. Do the operational test of the transfer pumps

NOTE : For this test the system must be in the automatic mode. This means the MAN legend in the AUTO FEED push switch must be off.

NOTE : Automatic transfer starts when the contents of both main tanks are less than 3300 KG (7250 LB) and the ground/flight sensors detect flight. The transfer stops when

one or both main tank contents becomes more than 3500 KG (7720 LB).

Action Result
(1) Install the target and anti-target, proximity sensing system set (tool No. 28-0-4733) part of target (tool No. 28-0-4733-08) on the LH ground/flight proximity sensor.

Action Result
(2) In the flight compartment on the FUEL control panel push (in) the CTR TANK PUMP 1 and 2 push switches (a) The ON legends in the CTR TANK PUMP 1 and 2 push switches come

on. (b) The fuel transfer from the center wing tank (CWT) to the main tanks starts. (c) On the tank contents displays (TCD's):

- The fuel quantity on the center

TCD decreases - The fuel quantities on the LH and

RH TCD increase.

NOTE: Each transfer pump transfers approximately 20 kg (45 lb) per minute.

Action Result
(3) Open the circuit breaker(s):
CENTER TANK PUMP 1 CTL P1 (a) The fuel transfer stops. (b) After 5 minutes the FAULT legend

(b) The FAULT legend in the AUTO FEED push switch goes off. (c) On the MFDU, the FUEL AUTO FEED message goes off. (7) Wait until the total fuel quantity in either main tank increases to approximately 3500 kg (7720 lb). (a) The fuel transfer stops.

NOTE: If the fuel quantity in either main tank does not get to 3500 Kg (7720 LB) because there is not enough fuel in the center tank, 15 minutes (if pre SBF100-31-067) or 1 minute (if post SBF100-31-067) after the center tank became empty: - the LOP legends in the CTR TANK PUMP push switches come on - the MFDU shows the CTR TK PUMPS alert message.

Action Result (8) Push (out) the AUTO FEED push switch. (a) The MAN legend in the AUTO FEED push switch comes on. (b) The fuel transfer starts again. (9) Push (in) the AUTO FEED push switch. (a) The MAN legend in the AUTO FEED push switch goes off. (b) The fuel transfer stops. (10) Push (out) the CTR TANK PUMP 1 and 2 push switches (a) The ON legends in the CTR TANK PUMP1 and 2 push switches go off.

Change FUEL TRANSFER on page 1 with the following:

FUEL TRANSFER

Fuel from the center tank is transfe rred to the wing tanks by two center tank pumps. Each pump supplies t he onside collector tank. When a collector tank is full, the excess fuel flows into the outer tank. Normally, when the center tank pum p push buttons are switched ON and the AUTO FEED push button is bl ank fuel transfer is controlled automatically. Automatic fuel transfer takes place onl y in flight when the fuel quantity in the wing tanks falls below a predetermined value. If the automatic transfer fails, fuel transfer can be controlled manually. Manual control is possible only w hen the AUTO FEED push button is depressed to MAN. In this case fuel transfer is controlled directly with the center tank pump push buttons. If the center tank becomes empty, a center tank pumps alert is presented. Pump Failures Pump failures will be indicated by a center tank pump low pressure alert. If one pump is inoperative the remain ing pump will result in a fuel asymmetry between the wing tanks. If both pumps are inoperative the center tank contents become unusable.
