Washington: Boeing Co Chief Executive Dennis Muilenburg acknowledged the company made mistakes in the development of a key safety system at the centre of two fatal 737 MAX crashes, and was hammered over his compensation at a US House hearing on Wednesday.
In the most intense exchange at the hearing so far, Representative Steve Cohen from Tennessee thundered at Muilenburg, "You said you're accountable. What does accountability mean – are you taking a cut in pay? Are you working for free from now on until you can cure this problem? These people's relatives are not coming back, they're gone. Your salary is still on," he said, gesturing to family members of crash victims attending the hearing.
"Congressman, it's not about the money for me," Muilenburg said.
Cohen interrupted: "Are you giving up any money?"
"Congressman, my board conducted a comprehensive review," Muilenburg said quietly, but clearly shaken.
Cohen thundered: "So you are saying you are not giving up any compensation at all? You are continuing to work and make $30 million dollars a year after the horrific two accidents that caused all of these people's relatives to go, to disappear, to die?"
"Congressman, again, our board will make those determinations," Muilenburg said.
"You're not accountable? You're saying the board's accountable?" Cohen said.
"Mr. Congressman, I am accountable sir," Muilenburg said.
Lawmakers also released Boeing documents that showed the company had considered adding an MCAS alert on the flight control panel to the 737 MAX. Another Boeing document warned that if a pilot failed to respond in more than 10 seconds to the software, activation could lead to a "catastrophic" failure.
Muilenburg acknowledged "we made some mistakes" on the development of MCAS, an anti-stall system that automatically pushed the plane’s nose down, leaving pilots fighting for control.
US Representative Peter DeFazio, who heads the House Transportation and Infrastructure Committee holding the hearing, pressed Muilenburg on why the company had not required data from crucial airflow sensors known as attack sensors when it originally designed the airplane. Muilenburg said the company had repeatedly asked the same question.
Last week, Indonesia investigators found Boeing failed to grasp risks in the design of MCAS.
“The design and certification of the MCAS did not adequately consider the likelihood of loss of control of the aircraft,” the report said.
The 737 MAX, when it returns, will have a number of new safeguards. It will take data from the attack sensors and not let MCAS activate more than once before a situation has been resolved.
DeFazio asked why Boeing approved MCAS when it was vulnerable to a single point of failure.
DeFazio also questioned why Boeing scrapped initial plans to install an MCAS "annunciator" alert and how pilots could be expected to recover if the system failed, when Boeing failed to disclose details on MCAS system to pilots. He also hammered Boeing's assumptions on how long it would take pilots to respond to a failure.
"I've talked to a lot of pissed off pilots," DeFazio said.
"We need answers. We need reforms on how commercial aircraft are certified," and how manufacturers like Boeing "are watched" by regulators, he added.
At one point in the hearing, Representative Rick Larsen of Washington state, where Boeing builds the 737, asked Muilenburg to name three mistakes the company made.
Muilenburg quickly listed Boeing's failure to disclose for months that it had made optional a cockpit alert flagging disagreement between the airflow sensors. "We got that wrong," he said.
Muilenburg also said, "clearly, we had some areas to improve" regarding MCAS. And finally he said the company should have been more "efficient and comprehensive" in its communications and documentation "across all of our shareholders."
But Muilenburg deflected a follow-up question on whether he could name specific individuals who were to blame for these mistakes, noting that larger "teams" were responsible for each of these areas.
Later, Congressman Dan Lipinski of Illinois, where Boeing is headquartered, told Muilenburg: "I am not sure what accountability means if you got a $15 million bonus after Lion Air," a reference to the crash in Indonesia.
Muilenburg began his opening remarks by turning and looking directly at family members of the victims seated closely behind him as he apologised for the 346 lives lost in crashes in Ethiopia and Indonesia.
In an earlier statement, DeFazio said the panel was aware of "at least one case where a Boeing manager implored the then-vice president and general manager of the 737 program to shut down the 737 MAX production line because of safety concerns." Boeing did not comment Tuesday on the allegation.
The hearing, the highest-profile congressional scrutiny of commercial aviation safety in years, heaps pressure on a newly rejiggered Boeing senior management team fighting to repair trust with airline customers and passengers shaken by an eight-month safety ban on its 737 MAX following the two crashes.
Muilenburg told reporters on Wednesday he believes the allegation was in response to concerns about a change in the increase of the production rate. He said Boeing was aware of those concerns and had acknowledged them.
Muilenburg said that he had met with some family members of the victims before the Wednesday's hearing.
When discussing conversations with family members during the hearing, Muilenburg repeatedly shifted in his chair and slowed his speech. "We talked about our commitment to never letting this happen again. Preventing any future accidents like this. One thing I wanted to convey to the families. These stories, they are always going to be with us. I wish we could change that."
