The US Federal Aviation Administration confirms it has cleared the Boeing 787 to return to service with 180min extended operations (ETOPS) intact.
That means the 787 can continue flying the same long-distance routes that include segments up to 3h flying distance from an emergency airfield.
The FAA had launched a separate review of the 787's ETOPS certification in tandem with the review of the aircraft's lithium-ion battery failures that grounded the fleet in early January.
Boeing always expected that the 787 ETOPS certification would not change as a result of the FAA's review.
The company included several reliability improvements in its campaign to gain approval for return to flight by the FAA.
