BOEING's under-fire CEO Dave Calhoun has quit after the aviation giant was plunged into crisis over a series of dangerous jet failures, reports The US Sun.

Mr Calhoun is set to be leaving at the end of the year, with other senior figures resigning following the death of a company whistleblower and a criminal investigation.

The planemaker said that Stan Deal, Boeing Commercial Airplanes president and CEO, would retire and Stephanie Pope would lead the business, effective immediately.

She recently became Boeing's COO after previously running Boeing Global Services.

Larry Kellner, chairman of the board, is also quitting and will have his last day at Boeing's annual meeting in May.

He has been replaced as chairman by Steve Mollenkopf, a Boeing director since 2020.

The departures come as airlines and regulators have been calling for major changes at Boeing following a slew of quality and manufacturing issues on their aircraft.

Scrutiny intensified after January 5, when a door plug on a relatively new Boeing 737 Max 9 blew out on an Alaska Airlines flight.

Mr Calhoun wrote to employees on Monday: "As you all know, the Alaska Airlines Flight 1282 accident was a watershed moment for Boeing.

"We must continue to respond to this accident with humility and complete transparency. We also must inculcate a total commitment to safety and quality at every level of our company."
