US lawmakers have accused Boeing of creating a "pattern of deliberate concealment" as it sought approval for its 737 Max 8 model to fly.
The accusation came as Boeing chief executive Dennis Muilenburg was quizzed by the Senate Commerce Committee.
Senators said they had serious concerns that Boeing put profits over safety as it rushed to get clearance.
Two deadly 737 Max 8 crashes killed a total of 346 people. Muilenberg admitted the firm had made "mistakes".
