Seat Fireblocking

In their continuing efforts to upgrade aircraft cabin safety and improve occupant survivability in aircraft accidents, the FAA requires that seat cushions installed on transport category airplanes and rotorcraft meet improved flammability standards.  Amendments were issued to require that new type design transport category airplanes and rotorcraft, as well as aircraft in air carrier operation under Part 121 and large airplanes operated under Part 135, be equipped with seat cushions providing a high degree of fire resistance.
