July 8 (Reuters) - Boeing ( BA ) has agreed to plead

investigation into two 737 MAX fatal crashes, the government

AeroSystems ( SPR ) for $4.7 billion in stock and Airbus

moved to take on the supplier's loss-making

Europe-focused activities.

157 people on board. China becomes the first country to ground

the MAX, followed by others including the U.S. FAA.

country potentially unfreezing deliveries of the 737 MAX.

JANUARY 2024: A mid-air cabin blowout compels Alaska Air ( ALK ) to

perform an emergency landing of its recently acquired 737 MAX 9

aircraft, prompting the FAA to ground 171 of these jets and

MAX output, but lifts the grounding of MAX-9s once inspections

were completed.

multiple instances where Boeing ( BA ) and supplier Spirit AeroSystems ( SPR )

give Boeing ( BA ) the authority to boost 737 MAX production.

July 1, 2024: Boeing ( BA ) acquires Spirit AeroSystems ( SPR ) back in an

to solve its quality hurdles and accelerate jet deliveries.

July 7, 2024: Boeing ( BA ) agrees to plead guilty to a criminal

fraud conspiracy charge and pay a fine of $243.6 mln to resolve

the U.S. Justice Department investigation into the two 737 MAX

fatal crashes in 2018 and 2019.
