Boeing Commercial Airplanes said today the company has completed the battery fixes to all 50 787s that were delivered to customers before being grounded earlier this year.

“Six of our eight in-service customers have returned to passenger service, with the others following in just a matter of days,” Randy Tinseth, the company’s vice president for marketing, wrote on his Randy’s Journal blog. “We can’t thank all of them enough for their patience, partnership and support over the past several months.”

He also gave credit to the teams “that fanned out across the globe to complete this work. It was truly an integrated effort across all of Boeing — involving engineering, development, fabrication, supply chain management, regulatory and repair services.”

The 787 Dreamliner was grounded in mid-January after lithium-ion batteries overheated on two planes operated by Japanese airlines. The root cause has not been identified.

Beoing assembles the 787 in North Charleston and Everett, Wash. The local plant has delivered four of the jets, all to Air India.
