Large transport airplanes operated under Parts 91, 121 and 125 are the subject of an extensive proposal that realigns the design, installation and maintenance requirements of fuel tank system electrical wiring with already-adopted new regulations covering maintenance and inspections of fuel tanks themselves. Part 91 aircraft with a maximum payload capacity of 7,500 pounds or more, or type-certified for a passenger capacity of 30 or more–such as the Boeing Business Jet and Airbus Corporate Jetliner–dash;are included in the proposal. The planned compliance deadline is Dec. 16, 2008, to coincide with the deadline for the new fuel tank maintenance regulations. Comments on the proposal are due by Feb. 3, 2006. For more information, contact the FAA at (425) 227-2315 or (202) 267-7355.
