Boeing Max ready to take flight, two years after pair of deadly crashes

- By David Koenig and Tom Krisher

After nearly two years and a pair of deadly crashes, the U. S. Federal Aviation Administra­tion has cleared Boeing’s 737 Max for flight.

The nation’s air safety agency announced the move early Wednesday, saying it was done after a “comprehens­ive and methodical” 20-month review process.

Regulators around the world grounded the Max in March 2019, after the crash of an Ethiopian Airlines jet. That happened less than five months after another Max flown by Indonesia’s Lion Air plunged into the Java Sea. A total of 346 passengers and crew members on both planes were killed.

Federal Aviation Administra­tion chief Stephen Dickson signed an order Wednesday rescinding the grounding. U. S. airlines will fly the Max once Boeing updates critical software and computers and pilots receive training in flight simulators.

The FAA says the order was made in cooperatio­n with air safety regulators worldwide.

The move follows exhaustive congressio­nal hearings on the crashes that led to criticism of the FAA for lax oversight and Boeing for rushing to implement a new software system that put profits over safety and ultimately led to the firing of its CEO.

Investigat­ors focused on antistall software that Boeing had devised to counter the plane’s tendency to tilt nose-up because of the size and placement of the engines. That software pushed the nose down repeatedly on both planes that crashed, overcoming

the pilots’ struggles to regain control. In each case, a single faulty sensor triggered the nose-down pitch.

The new software now requires inputs from two sensors to activate the software, which Boeing says does not override pilot controls like it did in the past.

The company changed the software so it doesn’t repeatedly point the nose of the plane down to counteract possible aerodynami­c stalling.

On a conference call with reporters, Dickson said the Max is now the most scrutinize­d transport aircraft in history, with over 40 FAA employees working tens of thousands of hours on the plane.

“The design changes we have overseen make it impossible for these accident scenarios to reoccur,” he said.

He said that if FA A knew after Lion Air what it learned during this review of the plane, it should have grounded the plane after the first crash.

“These events and the lessons we have learned as a re

sult have reshaped our company and further focused our attention on our core values of safety, quality and integrity,” Boeing CEO David Calhoun said in a statement.

The aircraft maker’s redemption comes in the middle of a pandemic that has scared away passengers and decimated the aviation industry, limiting its ability to make a comeback. Air travel in the U.S. alone is down about 65% from a year ago.

Boeing sales of new planes have plunged because of the Max and the coronaviru­s pandemic. Orders for more than 1,000 Max jets have been canceled or re

moved from Boeing’s backlog this year. Each plane has a sticker price of $99 million to $135 million, although airlines routinely pay less.

Boeing shares fell 2.1% to $205.55 in trading Wednesday afternoon. That’s about half of the all-time high of $440.62 reached on March 1, 2019, just days before the Ethiopian crash, but well above the $95 trough in March, when the pandemic caused massive disruption­s to travel and the global economy.

John Hansman, an aeronautic­s professor at MIT, said people typically avoid airplanes for a few months

after there are problems. But the Max case is unusual, and were it not for the novel coronaviru­s, Hansman said he would feel safe flying on a Max.

“It’s probably the safest airplane to be on,” he said.

Relatives of people who died in the crashes aren’t convinced. They accused Boeing of hiding critical design features from the FAA.

“The flying public should avoid the Max,” said Michael Stumo, whose 24-year- old daughter died in the second crash. “Change your flight. This is still a more dangerous aircraft than other modern planes.”
