"Boeing Faces Scrutiny as Investigation into Door Panel Incidents Widens"

The Justice Department's criminal investigation into the blowout of a panel on an Alaska Airlines Boeing 737 Max 9 jetliner has expanded, with subpoenas and a recently convened grand jury in Seattle being utilized. The incident, which occurred in January, led to the grounding of over 170 Max 9 planes and raised questions about construction flaws. The focus of the investigation may center on repairs to the plane's rivets and could potentially lead to a criminal prosecution. This development adds to the ongoing scrutiny faced by Boeing following previous safety issues and challenges in meeting airlines' demands.
