Embraer is facing a delay in the first flight of its Legacy 500 midsize executive jet because software development for the aircraft's fly-by-wire control unit is running behind schedule.
The Brazilian manufacturer says it is "revisiting the first flight schedule" while it "works closely with the supplier on this issue. Meanwhile, aircraft ground testing will commence on schedule."
Embraer has mated the wing and fuselage for the first of the three prototype Legacy 500s it has in production.
Systems installation is underway for the first aircraft, which is also having its vertical and horizontal stabilizers, cabin door, rudder and elevator assemblies fitted. Its Honeywell HTF7500E turbofans have been delivered to the assembly facility, said Embraer.
