Dave Calhoun

Boeing is giving subcontractor Spirit Aerosystems $425 million in advance payments so it can maintain production and allow the U.S. aviation giant to fulfill its orders, a regulatory filing has shown.

Boeing has faced intense scrutiny since a near-catastrophic incident in January, when a fuselage panel blew off of a 737 MAX mid-flight.

Dave Calhoun, the CEO of Boeing, has announced his resignation, marking the end of his tenure at the helm of the aerospace giant by the year's end. Calhoun's departure comes amidst a mounting crisis surrounding the safety of Boeing's aircraft.

Boeing announced Monday a leadership shakeup headlined by the departure of CEO Dave Calhoun as the aviation giant faces heavy scrutiny following safety incidents and manufacturing issues.

Besides Calhoun, who will stay in his post through the end of 2024, Boeing announced two other major changes to company management.

Boeing's CEO said the company could cancel the 737 MAX 10 if regulators don't certify the jet before new crew alerting system standards take effect in December, according to a report.

Boeing will pay $2.5 billion to settle a Justice Department investigation and admit that employees misled regulators about the safety of its 737 Max aircraft, which suffered two deadly crashes shortly after entering airline service.

The government and the company said on Jan. 7 that the settlement includes money for the crash victims' families, airline customers and a fine.
