NTSB Recommends Fuel Tank & Wiring Systems Safety Measures


Sep 20, 2000 

The National Transportation Safety Board (NTSB) has made a number of recommendations to the Federal Aviation Administration (FAA) regarding aircraft fuel tanks and wiring systems.

The recommendations include:
  • "Examine manufacturers' design practices with regard to bonding of components inside fuel tanks and require changes in those practices, as necessary, to eliminate potential ignition hazards. (A-00-105)"
  • "Review the design specifications for aircraft wiring systems of all U.S.-certified aircraft and (1) identify which systems are critical to safety and (2) require revisions, as necessary, to ensure that adequate separation is provided for the wiring related to those critical systems. (A-00-106)"
  • "Require the development and implementation of corrective actions to eliminate the ignition risk posed by silver-sulfide deposits on fuel quantity indication system components inside fuel tanks. (A-00-107)"
  • "Regardless of the scope of the Aging Transport Systems Rulemaking Advisory Committee's eventual recommendations, address (through rulemaking or other means) all of the issues identified in the Aging Transport Non-Structural Systems Plan, including:
    • the need for improved training of maintenance personnel to ensure adequate recognition and repair of potentially unsafe wiring conditions;
    • the need for improved documentation and reporting of potentially unsafe electrical wiring conditions; and
    • the need to incorporate the use of new technology, such as arc-fault circuit breakers and automated wire test equipment.
"To determine whether adequate progress is being made in these areas, the Safety Board believes that, within 90 days, the Federal Aviation Administration should brief the Safety Board on the status of its efforts to address all of the issues identified in the Aging Transport Non-Structural Systems Plan. (A-00-108)"

The complete recommendation letter is available on the Web.
