SBF100-28-047 May 10/10 Page 2 Revision 3, May 02/11 C. Reason

(1) Most of the present crossfeed indications are based on the crossfeed selection made by the flight crew and not on the actual positions of the crossfeed valve actuators. In combination with other factors, the indications have misled crews and resulted in single engine in-flight shutdowns and/or diversions. With the modified crossfeed indication logic, all crossfeed indications are based on the actual positions of the crossfeed valve actuators, and therefore provide crews with information on the actual status of the crossfeed system.

(2) As a result of a safety review of the fuel crossfeed system it was decided to change the electrical power supply to the crossfeed valve actuators and to the crossfeed indications on the fuel panel from the 28V DC bus to the 28V DC Emergency bus.

(3) To improve the reliability of the fuel crossfeed valve shut-off function and to reduce the response time of the crossfeed system to ON/OFF selections, the control of the crossfeed valve actuators will be changed from sequential to simultaneous.

(4) For aircraft serial numbers 11246 thru 11249, 11259, 11260 and 11263, the control of the engine fuel fire shut-off indication on the fuel panel changes. The CLOSED indication for engine 1 (2) is connected with the open limit switch of the engine 1 (2) fuel fire shut-off valve.

(5) If SBF100-28-047 Revision 3 is accomplished, SBF100-28-064 has to be accomplished concurrently. If a previous version of SBF100-28-047 has already been accomplished, no additional work is required and there is no concurrent requirement. However, to prevent economical damages it is in that case advised to carry out SBF100-28-064 as soon as possible. Fokker Services accepts no liability for any damages due to non-accomplishment of SBF100-28-064.

Reason for Revision

(1) This revision is made to:

- Incorporate SBCN SBF100-28-047/REV 2/01 and SBCN SBF100-28-047/REV 2/02

- Add SBF100-28-064 to the Concurrent Requirements

- Update the "Compliance" paragraph

- Change the effectivity of drawing W46254 for aircraft sn 11290

- Add AMM task numbers for some tests.

### - A collector tank low level alert may be expected if the collector tank quantity drops

below 500 kg / 1100 lb. This may occur in two conditions: - The wing tank quantity is low. - The jet transfer pumps are blocked. Fuel transfer from the wing tank to the collector tank and fuel supply is quaranteed. - Selecting X-FEED will prevent, in case of a fuel leak, the detection of the affected side.

Replace Remarks: from the FUEL ASYMMETRY procedure with the following:

Remarks:
- A fuel asymmetry alert may be expected if di fference between the wing tank quantities is more

than 350 kg / 770 lb. The alert will disappear wh en the difference in wing tank quantity reduces to below approx 250 kg / 550 lb. - Fuel asymmetry may occur as a result of pr olonged APU operation, single engine operation,

one center tank pump failure or obstructed cente r wing tank fuel supply to the collector tank, unequal wing tanking in combination with difference in fuel flow to the engines. - A fuel asymmetry as a result of a fast drop in quantity of one wing tank is considered a fuel leak

at that side. Apply FU EL LEAK PROCEDURE. - Selecting X-FEED will prevent, in case of a fuel leak, the detection of the affected side.

To isolate the LH from the RH fu el system, deselect X-FEED and apply FUEL LEAK PROCEDURE.

X-FEED ............................................................................................... ON
- Check that the DISAGR indication on the fuel panel comes on and extinguishes. - Check that the FUEL X-FEED ON message on the MFDS comes on.
X-FEED ............................................................................................... OFF
- Check that the DISAGR indication on the fuel panel comes on and extinguishes.
- Check that the FUEL X-FEED ON mess age on the MFDS extinguishes immediately

NOTE 1: the DISAGR light will illuminate a few seconds after de(selecting) X-feed, when the X-feed valves are in transit. This is normal system behavior. 2: After X-feed selection, it may take a few seconds before the FUEL XFEED ON message appears on the MFDS. This is normal system behavior. Use the following FUEL X- FEED VALV E DISAGREE procedure in case of a DISAGR indication on the fuel panel

 If DISAGR light remains on after selecting FUEL X-FEED:

X-FEED ......................................................................................... OFF CONSIDER FUEL X-FEED INOPERATIVE

 If DISAGR light remains on after deselecting FUEL X-FEED:

QUANTITY WING TANKS ............................................................ MONITOR STATUS: one or both x-feed valves may be not fully closed. REPORT TO MAINTENANCE
