Boeing Announces Significant Software Change For 737 Max Aircraft, Shares Unimpressed

Update (2:15 pm ET): The Wall Street Journal reports that Boeing is making a significant software change to a flight-control system in the new 737 MAX aircraft implicated in last year’s Lion Air crash.

The change, which was in the works before the Ethiopian Airlines plane crashed over the weekend, would mark a major shift from how Boeing originally designed a stall-prevention feature in the 737 MAX when it first delivered to airlines in 2017.

Boeing publicly released details about the planned 737 MAX software update on its website late Monday. A company spokesman confirmed the update would include a change to use multiple data feeds in MAX’s stall-prevention system—instead of the current reliance on a single sensor.

So far, Boeing shares are unimpressed.

Update (1:25 pm ET): The European Union’s aviation authority suspended all flight operations of the 737 Max 8 and larger 737 Max 9 in Europe, and banned flights from outside the region starting at 7 p.m. London time.The agency, which usually goes along with the FAA, said it was acting out of an abundance of caution and out of concern for passenger safety.

“The accident investigation is currently ongoing, and it is too early to draw any conclusions as to the cause of the accident,” EASA said in an emailed statement.

Over half the global fleet is now grounded.

Sending Boeing to yesterday's lows...

And judging by Boeing's CDS, it has further to fall...

As The Washington Post reports, calls from members of Congress to ban the Boeing 737 Max from U.S. airspace increased Tuesday, with Sen. Mitt Romney (R-Utah) joining several Democratic lawmakers in advocating for restrictions similar to those imposed by a growing list of other nations.

In a tweet, Romney said the Federal Aviation Administration should ground the planes "out of an abundance of caution for the flying public" following Sunday's Ethio­pian Airlines crash that killed all 157 people onboard.

As of late Tuesday morning, at least three other senators - Elizabeth Warren (Mass.), Dianne Feinstein (Calif.) and Richard Blumenthal (Conn.), all Democrats - called on the FAA to follow the lead of authorities in Britain, Germany, China and other nations.

Update (10:05 am ET): President Trump - now an aeronautics expert - has decided to chip in with some comments regarding Boeing's bans: "Airplanes are becoming far too complex to fly. Pilots are no longer needed, but rather computer scientists from MIT...often old and simpler is far better"

Trump then added that :"I don’t know about you, but I don’t want Albert Einstein to be my pilot."

Boeing shares have extended their drop to over 5%.

“Our thoughts go out to everyone affected by the tragic accident in Ethiopia yesterday.

Despite a reassuring (for some) statement from the FAA affirming that Boeing's 737 MAX 8 planes remain "safe" for flight, more countries on Tuesday have opted to ground the planes, including Singapore and Australia, in a rare break with US air-travel regulators.


Australia’s Civil Aviation Safety Authority said on Tuesday that it had suspended the operation of all Boeing 737 MAX aircraft flying to or from the country. Since no Australian airlines fly the aircraft (though its Virgin Air recently ordered dozens of new MAX 8s), the decision only impacts the Singaporean airlines SilkAir and Fiji Airlines, according to the FT.

“This is a temporary suspension while we wait for more information to review the safety risks of continued operations of the Boeing 737 MAX," said CASA' chief executive and director of aviation safety, Shane Carmody, in a statement to the Sydney Morning Herald.

Meanwhile, Virgin Australia has 40 MAX aircraft on order, and said it was "closely watching the situation", and hinted that it could change its order depending on the outcome of the investigation.

"With our first aircraft delivery not due until November this year, we believe there is sufficient time to consider the outcome of the investigation and make an assessment," a Virgin spokeswoman said.

So far, more than half of the airlines flying the 737 MAX 8 have grounded the planes. Yesterday, China, Ethiopia and Indonesia grounded said they would wait for more details of Sunday's crash to emerge, while a few Latin American countries followed suit. The plane only entered service in 2017, have grounded the aircraft, according to the New York Times.


Though Southwest Airlines and American Airlines have continued to use the aircraft, following the FAA's advice, they said they would be keeping an eye on events.

The planes are typically used for international flights, or covering long distances domestically:


Boeing has delivered 350 of the aircraft since it entered service, and has a backlog of more than 5,000 orders.

Boeing shares closed off the lows on Monday, but appeared to be headed lower once again in pre-market trading.
