Boeing's 'culture of concealment' to blame for 737 crashes

It blames a "culture of concealment" at Boeing, but says the regulatory system was also "fundamentally flawed".

Boeing said it had "learned many hard lessons" from the accidents.

But families of the victims accused the company and the regulator of continuing to hide information.

The US reportĀ is highly critical of both Boeing and the regulator, the Federal Aviation Administration (FAA).

Boeing chief fired but 737 concerns persist

More than 340 people died in the disasters, prompting accusations that Boeing put profit before safety.

Families of the victims welcomed Mr Muilenberg's resignation as overdue.

But they said Boeing's decision to replace him with a long-time board member raised questions about its commitment to change.

Boeing named David Calhoun, who has served on the firm's board since 2009 and is its current chairman, as chief executive and president.
