Boeing Co. said Tuesday that its grounded 737 Max jets likely won’t be approved to return to service until mid-2020.
Boeing BA, -3.55% shares were halted ahead of the announcement, when they were down 5.5%. They resumed trading off 4.8%.
“This updated estimate is informed by our experience to date with the certification process. It is subject to our ongoing attempts to address known schedule risks and further developments that may arise in connection with the certification process,” Boeing said in a statement.
That timeline “also accounts for the rigorous scrutiny that regulatory authorities are rightly applying at every step” of their review of the 737 Max’s flight control systems and future pilot training requirements, the company said.
The 737 Max jets have been grounded since March after two deadly crashes less than five months apart, and the company has been mired in criticism for the way it handled the plane’s certification and further missteps in the recertification.
A return-to-the-skies date, initially thought to take only a few weeks, has stretched for months on end, with the company announcing a 737 Max production halt in December.
Several allegations of Boeing mishandling the plane’s certification and post-crashes recertification have surfaced. Earlier this month, a trove of emails surfaced against Boeing, including a recent trove of internal emails showing Boeing workers mocking the 737 Max’s design and bragging about fooling federal regulators.
