The developments in the big league are rapid Boeing airline after the scandal and uproar that has been caused with the faulty parts on the aircraft.

Boeing CEO, Dave Calhounwill step down at the end of the year, and the company’s chairman will step down this spring, it was announced Monday.

The president of the company, Larry Kellneris leaving the board of directors in May, while Mr Stan Dealits president and CEO Boeing Commercial Airplanesis resigning immediately, according to reports.

The company’s stock, which has fallen about 25% since the start of the year, rose more than 2.8% on Monday.

On January 5, the tail plug of a passenger plane Boeing 737 Max 9 performed by Alaska Airlines lost mid-flight.

The result was FAA to order the grounding of Boeing aircraft at airports so that the required inspection can take place. The grounding of the jets resulted in thousands of flight cancellations by Alaska and United Airlines.

Preliminary investigations determined that the incident may have been caused by loose bolts that needed to be tightened. In late January, the FAA gave the green light for the Max 9 jets to return to service.

Last month, the National Transportation Safety Board issued the initial findings of its investigation, which concluded that bolts were missing from the Alaska Airlines plane.

Earlier this month, the FAA released the results of an audit of Boeing and Spirit AeroSystems, its main supplier. While investigating her supplier Boeing Spirit AeroSystems to eject the door plug, the agency found that engineers were using hotel key cards and liquid dish soap as makeshift tools to check the part’s fit.

The agency said it “found numerous cases where companies allegedly failed to comply with manufacturing quality control requirements.”

Days later, the head of the NTSB, Jennifer Homendytold Congress that Boeing had not fully cooperated with its investigation.

On March 8, Mr Ziad OjakliBoeing’s executive vice president of government operations, wrote in a letter to Sen. Maria Cantwell that the company could find no documents related to “opening and closing the door plug.”

The next day, Mr John Barnetta former Boeing quality control manager who exposed the company’s practices at the Charleston plant where he worked, has been found dead of a self-inflicted gunshot wound, authorities said.

Barnett filed a complaint against Boeing in court in 2017. The NTSB said he would hold an exploratory hearing for Boeing in early August.
