US securities officials fined Boeing $200 million over the aviation giant's misleading assurances about the safety of the 737 MAX airplane following two deadly crashes, regulators announced Thursday.

The plane model was involved in two major crashes that killed hundreds of people in less than one year. The plane was grounded worldwide for months as updates were made on the model.

The American Airlines flight was the first commercial flight in the US since Max was grounded in March 2019. Two plane crashes in Ethiopia and Indonesia meant authorities barred the plane from taking to the skies.

More than 20 months after it was grounded following two deadly crashes, Boeing's 737 MAX returned to the skies Wednesday with an incident-free commercial flight in Brazil.

US regulators have cleared Boeing's 737 MAX to return to service. The fleet has been grounded around the world since March 2019 following two deadly crashes involving the model. Some 346 people lost their lives in the accidents in Indonesia and Ethiopia.

The fourth-generation of Boeing's best-selling plane has been grounded globally since March 2019 after two fatal crashes. A certification flight test is a key step in the plane's return to service.

The plane maker has been trying to get its troubled airliner back in the skies after two crashes. Boeing has had its entire 737 Max fleet grounded since March last year.

The US aerospace giant said it is "keeping our customers and suppliers informed" about the new software issue. Aviation regulators have grounded the 737 Max across the globe after two deadly crashes.

The disclosed emails and messages are yet another embarrassment for the US aircraft manufacturer after two deadly crashes. Employees said they could mislead regulators to get the now-grounded 737 MAX certified.

Boeing replaced its chief executive in a bid to restore its reputation after two deadly crashes of its 737 MAX. Dennis Muilenburg quit on Monday after the board "decided that a change in leadership was necessary."

Boeing says it will temporarily suspend production of its globally grounded 737 MAX jets next month as safety regulators delay the aircraft's return to the skies after two crashes.

The head of the US Federal Aviation Administration has admitted that mistakes were made in approving Boeing's 737 Max plane for flight, before two deadly crashes involving the aircraft. Steve Dickson told US lawmakers that the FAA would not approve the plane's return to the skies before the end of year.
