Boeing CEO apologizes to families of plane crash victims before Senate grilling

WASHINGTON — Boeing CEO David Calhoun apologized to the families of victims of previous plane crashes involving the company's planes, including the 737 Max, before being grilled by senators Tuesday during a hearing on Capitol Hill.

Sen. Richard Blumenthal invited the families to the highly anticipated hearing, and many came holding posters of loved ones killed, including in the crash of Lion Air Flight 610 off Indonesia in 2018 and Ethiopian Airlines Flight 302 near Addis Ababa in 2019.

Before Calhoun began his opening statement, he turned and faced the families.

"I apologize for the grief we have caused," he said. "We are focused on safety."

Blumenthal thanked the families for joining the hearing.

"The issues before us today have real human consequences [and] real Life and death results," the senator said.

In his opening statement, Blumenthal hearing pressed Calhoun on whether the executive has made progress in turning the company around.

The senator mentioned the incident in January when a door plug blew out of an Alaska Airlines Boeing 737 Max 9 shortly after takeoff. He said that the "façade quite literally blew off the hollow shell that had been Boeing's promises to the world."

"Mr. Calhoun, you were brought in turn this company around," Blumenthal said. "But instead of asking what has caused Boeing's safety culture to erode, you and your colleagues in the C-suite have deflected blame, looked the other way, and catered to your shareholders instead."

The hearing came after not long after Blumenthal said he received new information about Boeing's questionable practices.

His office said on Tuesday said a current Boeing employee has come forward as a whistleblower identified the employee as Sam Mohawk, a quality assurance inspector for Boeing in Renton, Washington.

Mohawk alleges that Boeing is cutting corners by losing track of parts that have been labeled as non-conforming or not up to design standards, according to Blumenthal. Sometimes these parts get a second chance because they can be fixed or were mislabeled, but often they should be discarded. Still, the parts sometimes end up in newly built airplanes, Mohawk said, according to the senator.

"He said that he has been told by his supervisors to conceal this evidence from the FAA, and that he is being retaliated against as well," Blumenthal said in a statement.

A Boeing spokesperson said the company had received on Monday evening the documents supplied to Blumenthal by the whistleblower. The company is reviewing the claims now, the spokesperson said on Tuesday.

"We continuously encourage employees to report all concerns as our priority is to ensure the safety of our airplanes and the flying public,” the spokesperson said.

The latest whistleblower stepped forward as Boeing CEO David Calhoun prepared to sit for a Senate hearing on his company's "broken safety culture" on Tuesday afternoon. Previous whistleblowers have accused the Arlington, Virginia-headquartered company of cutting corners on safety practices as it builds aircraft.

Calhoun in January said Boeing was "accountable for what happened" during the Alaska flight.

"Whatever the specific cause of the accident might turn out to be, an event like this must simply not happen on an airplane that leaves one of our factories," he said at the time. "We simply must be better. Our customers deserve better."
