Airbus’ A350-900 has moved closer to entering service after the FAA granted the aircraft type certification.
It follows EASA awarding the A350-900 certification in September.
Both certifications followed a series of trials to ensure airworthiness criteria were met, including an 81,700nm (151,300km) route proving tour.
The A350-900 can carry 315 passengers and has a range of 7,750nm (14,500km).
Powered by Rolls-Royce’s Trent XWB, the aircraft is expected to enter service with launch customer Qatar Airways by the end of the year.
