Boeing CEO Dave Calhoun will step down at the end of the year, the company said in an announcement Monday.

The leadership shakeup comes amid fallout from a high-profile safety failure onboard an Alaska Airlines flight in January, when a door plug blew out of Boeing’s 737 Max 9 aircraft while the plane was in flight.

In a statement on Monday, Calhoun acknowledged the challenges facing Boeing.

“The eyes of the world are on us, and I know that we will come through this moment a better company,” Calhoun said. “We will remain squarely focused on completing the work we have done together to return our company to stability after the extraordinary challenges of the past five years, with safety and quality at the forefront of everything that we do.”
