That earlier strike came as Boeing faced multiple federal investigations after a door plug blew off a 737 Max during an Alaska Airlines flight. The incident renewed safety concerns around the 737 Max, which was already linked to two crashes in 2018 and 2019 that killed 346 people. The Federal Aviation Administration capped Boeing's 737 Max production at 38 planes per month until it is satisfied with manufacturing safeguards. Ortberg said the company has reached that limit and plans to request approval to increase production later this year. Boeing reported narrower losses of $611 million in the second quarter, compared to $1.44 billion in the same period last year, alongside improved revenue.
