Differences –EZAP/SFAR 88• EZAP– zonal assessment– physical failure based– mitigates smoke/fireevents throughout allzones• SFAR 88– systems assessment– functional based– precludes developmentof ignition sources infuel tank system6

Similarities –EZAP/SFAR 88• Addresses EWIS failure conditions• Can be incorporated into MSG-3 process• Necessitates development of complianceplan• Necessitates review by ACO prior to MRB7
