Boeing: Texas prosecutors open investigation targeting subcontractor. Spirit AeroSystems manufactures fuselages and other large structural parts for aircraft, including Boeing's flagship 737.

"Apparent manufacturing defects have led to numerous disturbing or dangerous incidents" on 737 models, detailed Texas Attorney General Ken Paxton. The investigation comes just days after the announcement of the departure at the end of the year of Boeing CEO Dave Calhoun. The American giant Boeing is in turmoil after a succession of quality and safety problems on its planes.
