March 26 is the comment deadline for a widespread proposal that would require operators and manufacturers of airliner-size airplanes (including bizliners) to incorporate technology to meet reduced levels of flammability
exposure in fuel tanks “most prone to explosion.” The rules would apply to new airframe designs, as well as some 3,200 U.S.-registered Airbus and Boeing airplanes with center-wing tanks currently in operation. Airplanes with a certified passenger capacity of 30 or more or a payload capacity of 7,500 pounds or more operated under FAR Part 91, 121 and 125 would be affected.
