## Abstract

The FAA extends, by 24 months, the date for operators to comply with the fire penetration resistance requirements of thermal/ acoustic insulation used in transport category airplanes manufactured after September 2, 2007. This extension is from September 2, 2007, to September 2, 2009. This action is necessary to allow airframe manufacturers enough time, after getting an acceptable certification test facility, to select and certificate appropriate installations.
