U.S. Transportation Secretary Sean Duffy said he’s asked Boeing CEO Kelly Ortberg to provide a “full accounting” of the planemaker’s actions to improve quality and safety in the wake of a near-catastrophe early last year.

In a post on X, Duffy said he asked that Ortberg come to Washington “as soon as possible,” and he planned to visit Boeing himself to evaluate the steps the company has taken “to ensure its planes meet the highest safety standards.”

U.S. aviation safety regulators significantly stepped up their oversight of Boeing after a door-sized panel blew off an airborne 737 Max in January 2024. U.S. Federal Aviation Administration (FAA) has placed additional inspectors at Boeing’s airplane factories, and imposed a cap on production of the cash-cow 737 Max jetliner, limiting output at no more than 38 jets per month.

Boeing has focused intently on improving quality and safety and is monitoring — along with the FAA — six measures of the health of its factories and supply chain to guide the pace of work inside its plants, such as the amount of manufacturing tasks that are performed out of the normal sequence.

Boeing representatives did not immediately respond to a message seeking comment.
