Embraer on February 20 obtained FAA certification and JAA recommendation for its 70- to 78-passenger Model 170 regional twinjet, some 18 months later than originally planned. The delay has been particularly irksome for Embraer 170 launch customers US Airways and Alitalia. The certification includes a Honeywell fly-by-wire system, to which Embraer earlier attributed to program delays.
