That's after a door panel broke off one of its Max 9 jets in midair last month, sparking a fresh crisis for the plane maker.

The MAX leader, Ed Clark, had been with Boeing for 18 years.

He had overseen production in the Washington state facility where the plane involved in the incident was completed.

Clark's departure is part of a larger shake-up Boeing announced on Wednesday, including a new senior position for quality and safety.

Regulators have curbed Boeing production and the company's been closely scrutinized by lawmakers and clients since the January incident.

A memo announcing the shake-up from CEO Stan Deal said Boeing was working to ensure that quote "every airplane we deliver meets or exceeds all quality and safety requirements."

The panel blowout had happened on a brand-new Alaska Airlines plane.

It forced pilots to make an emergency landing while passengers were exposed to a hole 16,000 feet above ground level.

The panel serves as a plug on some 737 MAX 9s instead of an extra emergency exit but the one on the Alaska Airlines jet appeared to be lacking four crucial bolts, according to a preliminary report earlier this month.

The report also said the door plug in question was removed to repair rivet damage but there has been no evidence the bolts were re-installed.

The findings angered Boeing's airline customers with some, like Alaska Airlines, announcing plans to implement stricter quality checks on planes before they depart the Boeing factory.
