| 2010-33000 | Airworthiness Directives; The Boeing Company Model 777-200, -300, and -300ER Series Airplanes | Proposed Rule | We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require installing an auto shutoff feature for the center override/jettison fuel pumps, and installing power control circuitry for the center override/jettison and main jettison fuel pumps. This proposed AD would also require installing new software in the electrical load management system (ELMS) electronics units in certain power management panels; installing airplane information management system 2 (AIMS-2) software in the AIMS-2 hardware; and making certain wiring changes. This proposed AD was prompted by results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. | 2010-12-30 | 2010 | 12 | https://www.federalregister.gov/documents/2010/12/30/2010-33000/airworthiness-directives-the-boeing-company-model-777-200--300-and--300er-series-airplanes | https://www.govinfo.gov/content/pkg/FR-2010-12-30/pdf/2010-33000.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to adopt a new airworthiness directive (AD) for the products listed above.
