Boeing CEO Dave Calhoun will apologize for the company’s recent safety failures and acknowledge cultural issues in his Senate testimony.

However, he will refute claims that Boeing retaliated against whistleblowers who raised safety concerns.

In his prepared remarks, Calhoun will admit that Boeing’s culture is imperfect but emphasize ongoing efforts to address and improve it.

This comes amidst intense scrutiny following a January 5 incident where a door plug blew off an Alaska Air Boeing 737 Max, prompting numerous federal investigations and congressional hearings, CNN has reported.

The Federal Aviation Administration has mandated safety improvements before Boeing can resume normal production, affecting airlines and leading to higher fares for passengers.
