Commercial Airplanes 757 Service Bulletin
SPECIAL ATTENTION SummaryNumber: 757-28-0121Original Issue: August 18, 2010 ATA System: 2841 SUBJECT: FUEL-Fuel Quantity Indicating System (FQIS)- Fuel Quantity Processor Unit, Low Fuel Quantity Indication Test BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS SERVICE BULLETIN IMMEDIATELY.
CONCURRENT REQUIREMENTS None.
BACKGROUND This service bulletin provides test procedures to make sure that the Engine Indication and Crew Alerting System (EICAS) receives both, the LOW FUEL and the FUEL CONFIG discrete signals from the Fuel Quantity Processor Unit (FQPU), and the Fuel Quantity Indicating System (FQIS), is functioning correctly. If this service bulletin is not incorporated flight crews may be unaware of low fuel situations that can lead to fuel exhaustion and extreme emergency measures.
A 757-200 operator reported that the Low Fuel Indicating System failed to alert the flight crew that the fuel in Left Hand (LH) and Right Hand (RH) main tanks were depleted below the minimum 2,200 lbs in either tank. The Low Fuel Threshold is 2,200 lbs of fuel for either Main Fuel Tank. When the fuel in either LH or RH main tank is below 2,200 lbs, the EICAS should receive both the LOW FUEL and FUEL CONFIG discrete signals from the FQPU in order for EICAS to display the LOW FUEL caution message.
The Operator reported to Boeing that the airplane arrived at it’s destination with main tank fuel levels below the Low Fuel Threshold. The next flight crew reported 8,000 lbs of fuel in the Center Wing Tank (CWT), 1,800 lbs of fuel in the Right Hand Main Fuel Tank and 1,400 lbs of fuel in the Left Hand Main Fuel tank.
Boeing determined this to be a safety issue. Operators can expect to eliminate similar safety incidents by doing the interval tests in accordance with this service bulletin.
757/767-SRP-28-0124 is related to this service bulletin.
ACTION Test the Low Fuel Quantity Indicating System to make sure that the, Low Fuel Indication, and the Fuel Configuration indication are functioning correctly.
Make sure the EICAS displays the "LOW FUEL" caution message and the "FUEL CONFIG" light on the Pilots Overhead Panel (P5 Panel) comes "ON".
