Before Ethiopian Crash, Boeing Resisted Pilots’ Calls for Aggressive Steps on 737 Max -- By David Gelles and Natalie Kitroeff

Weeks after the first fatal crash of the 737 Max, pilots from American Airlines pressed Boeing executives to work urgently on a fix. In a closed-door meeting, they even argued that Boeing should push authorities to take an emergency measure that would likely result in the grounding of the Max.

The Boeing executives resisted. They didn’t want to rush out a fix, and said they expected pilots to be able to handle problems.

Mike Sinnett, a vice president at Boeing, acknowledged that the manufacturer was assessing potential design flaws with the plane, including new anti-stall software. But he balked at taking a more aggressive approach, saying it was not yet clear that the new system was to blame for the Lion Air crash, which killed 189 people.

“No one has yet to conclude that the sole cause of this was this function on the airplane,” Mr. Sinnett said, according to a recording of the Nov. 27 meeting reviewed by The New York Times.


Less than four months later, an Ethiopian Airlines flight crashed, killing all 157 people on board. The flawed anti-stall system played a role in both disasters.

Boeing is facing intense scrutiny for the design and certification of the Max, as well as for its response to the two crashes. There are multiple investigations into the development of the Max. And in recent days, unions representing pilots from American Airlines and Southwest Airlines have received federal grand jury subpoenas for any documents related to Boeing’s communications about the jet, according to three people with knowledge of the matter.

The Federal Aviation Administration is also under fire for its role in approving the Max, and its decision to wait for days after the second crash to ground the plane. At a Wednesday congressional hearing, lawmakers will grill federal regulators about how the Max was certified.

Boeing declined to comment on the November meeting. “We are focused on working with pilots, airlines and global regulators to certify the updates on the Max and provide additional training and education to safely return the planes to flight,” the company said in a statement.

American Airlines said in a statement that it was “confident that the impending software updates, along with the new training elements Boeing is developing for the Max, will lead to recertification of the aircraft soon.”

The hourlong November meeting, inside a windowless conference room at the Fort Worth headquarters of the American Airlines pilots’ union, was confrontational at times. At the table was Mr. Sinnett, along with Craig Bomben, a top Boeing test pilot, and one of the company’s senior lobbyists, John Moloney. They faced several union leaders, many of them angry at the company.

Michael Michaelis, an American pilot, argued that Boeing should push the F.A.A. to issue what is known as an emergency airworthiness directive.

The F.A.A. had already issued one directive after the Lion Air crash, instructing airlines to revise their flight manuals to include information on how to respond to a malfunction of the anti-stall system known as MCAS. But Mr. Michaelis pushed Boeing to consider calling for an additional one to update the software.

Such a procedure would have required Boeing and airlines in the United States to take immediate action to ensure the safety of the Max, and would have likely taken the jet out of service temporarily.

“My question to you, as Boeing, is why wouldn’t you say this is the smartest thing to do?” Mr. Michaelis said. “Say we’re going to do everything we can to protect that traveling public in accordance with what our pilots unions are telling us.”

Mr. Sinnett didn’t budge, saying that it remained unclear that the new software, which automatically pushes the plane’s nose down, was responsible for the Lion Air crash. He added that he felt confident that pilots had adequate training to deal with a problem, especially now that pilots — who were not initially informed about the new system — were aware of it.
