AD: Boeing

AD NUMBER: 2010-20-12

MANUFACTURER: The Boeing Company Model 747-400, 747- 400D, and 747-400F Series Airplanes
SUBJECT: Airworthiness Directive 2010-20-12

SUMMARY: This AD requires installing a hot short protector (HSP) for the fuel quantity indicating system (FQIS) of the center fuel tank and, for certain airplanes, the horizontal stabilizer fuel tank. This AD results from fuel system reviews conducted by the manufacturer. The FAA is issuing this AD to prevent an electrical hot short from a source outside the FQIS to the densitometer wiring from causing failure of the FQIS densitometer resistors, which could result in an ignition source inside the center or horizontal stabilizer fuel tanks. An ignition source, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. This AD is effective November 5, 2010.
