"A lot of great things are happening at our 787 factory in Everett," Boeing Vice President of Marketing for Commercial Airplanes Randy Tinseth wrote in a blog post on the company's website.
"In just the past few days, the first major piece of the 787-9 arrived — and the first 787 built at the increased production rate of 7 airplanes per month rolled out of the factory," he continued. "Today, we marked another important moment as 787 deliveries got back underway with a delivery to ANA."
Boeing announced last week that it was increasing its production rate of 787s because the company said demand for the airplane was impacted by its three-month grounding.
The Dreamliner was grounded from mid-January until April after a string of incidents in which the aircraft's lithium-ion batteries caused at least one fire and several other close calls.
Two of the planes that malfunctioned were owned by ANA Airlines and its Japanese competitor Japan Airlines. A third plane owned by United Airlines, which was the only U.S. airline flying 787s, exhibited similar issues before the FAA rescinded its certification of the Dreamliner.
Tinseth said the grounding did not impact Boeing's ability to sell the 787 to airlines, however.
"The health of our 787 factories in Everett and North Charleston has never been better or more efficient," he wrote. "And despite the disruption in deliveries over the past several months, we still expect to deliver all the 787s we originally planned to by the end of the year."
