Boeing CEO bolsters shareholder confidence
Boeing Co Chief Executive Dennis Muilenburg tried to bolster shareholder confidence in the company on Monday in his first general meeting since two fatal crashes of the 737 MAX triggered the jet’s grounding, lawsuits and investigations.
Battling the biggest crisis of his tenure, Muilenburg said the company was making steady progress towards getting approval for new software as questions linger over the safety of its fastest-selling airplane.
Boeing is under pressure to deliver a software fix to prevent erroneous data triggering an anti-stall system called MCAS and a new pilot training package that will convince global regulators, and the flying public, that the aircraft is safe.
Boeing has acknowledged that the accidental firing of the software based on bad sensor data was a common link in the separate chains of events leading to the two accidents.
Boeing hopes to for MAX ungrounding in July
Boeing Co has told some 737 MAX owners it is targeting U.S. Federal Aviation Administration approval of its software fix as early as the third week of May and the ungrounding of the aircraft around mid-July, two sources told Reuters.
The dates are part of a provisional timeline that Boeing has shared in meetings with airline customers as it explains an upgrade to software that played a role in two fatal crashes and led to the worldwide grounding of its MAX 737 jetliner in March.
However, Boeing has not yet submitted its completed software package to the FAA for approval, two other sources said.
None of the sources, who were not authorized to speak publicly, said they knew for sure how long the re-certification process will take.
A Boeing spokeswoman said the company is focused on the safe return to service of the MAX and its engagement with global regulators and customers.
What will it take to unground MAX planes?
On April 1, the FAA said that once it received Boeing’s completed software package it would run a rigorous safety review before approving the software for installation.
The agency also plans to work with other international regulators on MAX certification in their countries and regions before lifting the flying suspension in the United States, with Boeing prepared to address any concerns, one source said.
Aside from the software certification, international regulators must also decide on new pilot training.
This process is separate from an FAA-led international review panel, which the agency has said may not be completed before the MAX flying suspension is lifted.
The two largest U.S. MAX owners, Southwest Airlines Co and American Airlines Group Inc, removed the aircraft from their flying schedules into August but have said they could use their MAX jets as spares if they are ungrounded sooner.
United Airlines, with 14 MAX jets, said last week that it expected the aircraft to return to service this summer, with deliveries resuming before the end of the year.
Boeing halted MAX deliveries to customers after the grounding in mid-March and said earlier this month that it would cut 737 production to 42 airplanes per month from 52.
One industry source said that as of last week, Boeing planned to keep the lower production rate in place for two months, meaning it aims to resume a rate of 52 aircraft in July but the timeline could shift.
Global airlines have had to cancel thousands of flights and use spare aircraft to cover routes that were previously flown with the fuel-efficient MAX.
Boeing’s first quarter profits fall by 20%
Boeing says its profits for the first quarter of 2019 had fallen by 20% because of lower deliveries of its now controversial and grounded 737-Max jets.
The US plane manufacturer also withdrew profit projections for the year saying it will publish new figures soon as it resolves issues around the now grounded fast-selling product.
The March 10 Ethiopian Airlines crash in Bishoftu was the second deadly crash of the 737 Max in five months. The first was a Lion Air crash in October 2018.
The model was grounded about two weeks after the Ethiopian incident and US federal authorities are currently undertaking a rigorous certification process as Boeing tries to correct the automated flight control system blamed for the crashes.
All 157 people aboard the ET302 crash died when the jet crashed minutes into a flight bound for the Kenyan capital Nairobi. It had set off from Addis Ababa’s Bole International Airport.
Who are the reviewers?
U.S. Transportation Secretary Elaine Chao said last month the panel would be co-chaired by retired Air Force General Darren McDew, the former head of the U.S. Transportation Command, and Lee Moak, a former president of the Air Line Pilots Association.
Chao on Monday said she was naming NASA’s former aviation safety program director Amy Pritchett and Gretchen Haskins, chief executive of HeliOffshore Ltd, an international expert in aviation safety and a former U.S. Air Force officer.
She also named Kenneth Hylander, chief safety officer at Amtrak and a former senior safety executive at Delta and Northwest airlines, and J. David Grizzle, chairman of the board of Republic Airways and a former FAA chief counsel.
Federal prosecutors, the Transportation Department’s inspector general and lawmakers are investigating the FAA’s certification of the 737 MAX 8 aircraft. A joint review by 10 governmental air regulators is also set to start April 29.
US names experts to review Boeing certification process
The United States Transportation Secretary Elaine Chao on Monday named four experts to a blue-ribbon committee to review the Federal Aviation Administration’s (FAA) aircraft certification process after two deadly Boeing 737 MAX crashes killed nearly 350 people.
The committee is “specifically tasked to review the 737 MAX 800 certification process from 2012 to 2017, and recommend improvements to the certification process.”
U.S. lawmakers have criticized the FAA’s program that allows Boeing Co (BA.N) and other manufacturers to oversee the process that ensures air worthiness and other vital safety aspects of new aircraft.
Boeing makes final changes to 737 MAX planes
Boeing has conducted a final test flight of a 737 MAX model with an updated anti-stall system prior to its certification by aviation authorities, the aerospace manufacturer said Wednesday.
CEO Dennis Muilenberg tweeted a video where he said the test flight was carried out on Tuesday, adding that test pilots have completed 120 flights totaling more than 203 hours of airtime with the software fix for the Maneuvering Characteristics Augmentation System (MCAS).
‘‘More than 85 percent of the 50-plus MAX operators around the globe also have had the opportunity to see the update in action during simulator sessions,” added Muilenberg.
All 737 MAX aircraft have been banned from the world’s skies since days after the Ethiopian Airlines crash on March 10.
The Federal Aviation Administration on Tuesday said a portion of the proposed modifications were “operationally suitable” but said it would not rush towards approval.
Kenyan family sues Boeing
A Kenyan family in Chicago is suing American aviation giant Boeing over the March 10 Ethiopian Airlines crash that killed 157 people, lawyers and family members said on Tuesday.
Siblings of 29-year-old engineer George Kabau said they wanted to force the company to release documents and emails relating to its 737 MAX 8 model, which was grounded worldwide after two major plane crashed in Ethiopia and Indonesia.
A preliminary report released earlier this month indicated Ethiopian Airlines pilots wrestled with a computer system that repeatedly ordered the nose down because of faulty sensor data. The same system was a focus of the preliminary report into the October Lion Air crash in Indonesia, which killed 189 people.
Kabua’s sister, Esther Kabau-Wanyoike, choked up as she told a press conference that she wanted to use her brother’s death to improve aviation safety.
“He didn’t leave a child. My mum is devastated,” she said. “We can use his demise to ensure safer travel for all.”
Dozens of families are already suing Boeing over the Lion Air crash, and three lawsuits have already been lodged over the Ethiopian Airlines crash, by the families of two Americans, including consumer activist Ralph Nader’s great niece, and a Rwandan.
U.S. lawyer Nomi Husain, who is also representing one of the American families, said the lawsuit was filed in Chicago late on Monday. The family was seeking to hold Boeing accountable, he said.
“We want to let the litigation process play out,” he said. “When you put profits over safety, you will be held accountable and you will pay a price.”
Kenya had the largest number of citizens on the flight from Addis Ababa to Nairobi. At least 32 Kenyans were on board, the airline said at the time, although that number may be larger because some of the travellers were dual nationals and the full manifest has still not been released.
Branding experts weigh in
Brand Finance, a UK-based consultancy that tracks the value of global brands, rejected the idea that Boeing should abandon the MAX brand but said its corporate reputation was in the firing line.
“This has without a doubt damaged Boeing’s reputation and we foresee a dent to the (Boeing) brand’s value at over $12 billion,” Chief Executive David Haigh said by email when asked about Trump’s comments.
“This is a temporary blip in the long run for Boeing,” he said, adding Toyota and others had recovered from similar high-profile crises without a drastic rebranding exercise.
Brand Finance had previously estimated the damage to the value of Boeing’s reputation at $7.5 billion immediately after the March 10 crash of an Ethiopian Airlines jetliner, the second fatal accident involving the 737 MAX in five months.
Boeing has the world’s most valuable aerospace brand, having seen the value of its overall corporate image rise by 61 percent to $32 billion in 2018, according to the same branding firm.
Donald Trump’s advice to Boeing
U.S. President Donald Trump on Monday urged Boeing Co to fix and “rebrand” its 737 MAX jetliner following two fatal crashes, as regulators worldwide continue to work with the planemaker to review its grounded best-selling aircraft.
“What do I know about branding, maybe nothing (but I did become President!), but if I were Boeing, I would FIX the Boeing 737 MAX, add some additional great features, & REBRAND the plane with a new name. No product has suffered like this one. But again, what the hell do I know?” Trump tweeted.
The plane’s grounding has also threatened the U.S. summer travel season, with some airlines removing the 737 from their schedules through August.
Trump issued the tweet as Boeing tries to restore trust in its fastest-selling jet, the main source of profits and cash at the Chicago-based planemaker which has won some 5,000 orders or around seven years of production for the aircraft.
Ivanka Trump honours victims on trip to Ethiopia
White House advisor and daughter of U.S. president Donald Trump on Monday visited the Holy Trinity Church in Addis Ababa to pay respects to victims of the March 10 Ethiopian Airlines crash.
Ivanka is on a two-day official visit to Ethiopia to promote women empowerment. She arrived on Sunday and is due to fly out later today to Ivory Coast.
In all black attire with a veil, Ivanka lighted candles, laid a wreath at the place where the coffins were kept. Weeks after the incident, the church undertook a mass and burial which was effectively sand in coffins because bodies were not immediately identifiable.Ivanka Trump in Ethiopia for two-day visit
Reports say body parts retrieved from the crash site will be sent to the United Kingdom for DNA tests. Donald Trump also spoke to Prime Minister Abiy Ahmed weeks ago in connection with the accident which has adversely affected the U.S. plane maker Boeing.

US regulator meets commercial airlines
The US Federal Aviation Administration (FAA) will on Friday meet with American commercial airlines that use the Boeing 737 MAX, which has been grounded worldwide since mid-March following two accidents that killed 346 people.
“The purpose of this meeting is for the FAA to gather facts, information, and individual views to further understand their views as FAA decides what needs to be done before returning the aircraft to service,” the agency said in a statement.
Security representatives from American Airlines, Southwest and United will be at the meeting, as well as representatives from their pilot unions.
American and Southwest use the 737 MAX 8, while United has 737 MAX 9 aircraft in its fleet.
The FAA recently formed an action committee with NASA and international civil aviation authorities to help certify the fix to the MCAS anti-stall system Boeing developed specifically for the 737 MAX.
The MCAS is believed to have been a key factor in both the Ethiopian Airlines crash and the Lion Air crash in Indonesia that killed 189 people in October.
What has Boeing done to fix MCAS?
Boeing CEO Dennis Muilenberg said Thursday that the changes the aircraft manufacturer is working on will make the 737 MAX “even safer by preventing erroneous angle of attack sensor readings” from triggering the MCAS.
Speaking in public for the first time since the Ethiopian Airlines crash, Muilenberg told a conference in Dallas, Texas that Boeing has conducted 96 test flights of the modified 737 MAX and the pilots have taken part in more than 159 hours of tests.
He added that he had been on board one test flight in Seattle and that the software update “functioned as designed.”
“In these challenging times, I am even more confident we will come through this even stronger,” he said in conclusion, adding he “(regrets) the impact the grounding has had on all of our airline customers and their passengers.”
Muilenberg is expected to answer questions from the financial community on April 24 as part of the release of Boeing’s first quarter results.
10 key incidents since ET302 crash
April 10, 2019 marks exactly a month since the Ethiopian Airlines Boeing 737 Max crashed in the town of Bishoftu in Ethiopia’s Oromia region.
The flight was on its way to the Kenyan capital Nairobi but it made only six minutes out of the over two hours flight before crashing and killing all persons on board.
This article looks back at 10 critical moments after the crash as part of our rolling coverage of the incident which was keenly followed by our audience in March.
1 – All 157 aboard killed
2 – Boeing 737 MAX 8s grounded worldwide
3 – Black boxes flown to Paris
4 – First burial ceremony held in Addis Ababa
5 – PM speaks with Trump over incident
6 – Airline, customers fights foreign media misreport on crash
7 – Ethiopian wins award in Kigali
8 – Preliminary report released
9 – Boeing admits errors vows robust response
10 – DNA samples of victims to be flown to UK for testsTECHNICAL ANALYSIS: THE BOEING CRISIS: ONE MONTH LATER.
DNA test of victims to be undertaken in London
In the wake of the accident, Ethiopian authorities reported that all victims had been burnt beyond recognition. Subsequently, grieving families were given earth for burial ceremonies that took place last month.
The Bloomberg news portal is reporting that Ethiopia will send DNA samples from the Boeing 737 MAX 8 crash for identification tests in London.
The accident killed all 157 people on board – 149 passengers and eight crew members. Authorities will transport human tissues gathered by a team led by Interpol and the U.K.’s Blake Emergency Services.
Paris became a center of attraction after the crash when Ethiopia opted to send black boxes – flight recorders – for information on them to be downloaded.
Germany was first mentioned as destination for the exercise but they turned down the request due to the complicated nature of the test. The information was downloaded by the multi-pronged team.
It was the basis on which Ethiopian government released a preliminary crash report last week. Boeing via its CEO has admitted errors in a key software and pledged robust responses. The plane maker has suffered huge losses in aftermath of the incident.
Ethiopian considers Boeing purchase orders
The Bloomberg news portal is reporting that Ethiopian Airlines is reconsidering its orders for Boeing 737 MAX jets following the release of a preliminary report into the ET302 crash.
“We may reach the decision: Look, we just had a very tragic accident a few weeks ago, and customers still have the accident in their mind. So it will be a hard sell for us to convince our customers,” Tewolde GebreMariam is quoted to have said.
Ethiopian had earlier ordered 30 of the now controversial jets with five delivered at the time of the crash. The airline will not take delivery of the remaining 25 anytime soon – or perhaps at all, Tewolde said.
According to him, the decision on the 737 Max purchases will come after Boeing offers a software fix to a system implicated in the crash – and an earlier Lion Air crash. They will also base their decision based on what regulators and other airlines do.
“Our situation is quite different from the others, because we are the victim. You can imagine the stigma that will be attached with the airplane,’’ Tewolde added.
Ethiopian, Africa’s biggest flier, will need to do a lot of work by way of trying to convince its staff and customers before they resume use of the jet which has been grounded worldwide in the wake of the March 10 crash.Bloomberg: Ethiopian Carrier Rethinks 737 Max Purchase, Citing ‘Stigma’
Indonesia, Singapore join investigations
Indonesia will send two investigators to Ethiopia to assist in a probe and exchange data on two fatal crashes of Boeing 737 MAX jets since October, the head of the country’s air safety agency told Reuters on Friday.
Indonesian investigators will travel to the Ethiopian capital Addis Ababa on April 15, said Soerjanto Tjahjono, head of the National Transportation Safety Committee (KNKT).
“They will help in assisting Ethiopia. We will study the data to assess whether there are similarities or whether there is any new information from the accident,” Tjahjono said by telephone.
A preliminary report on the Ethiopian Airlines’ crash showed on Thursday that the doomed jet travelled at an excessive speed and was forced downwards by a wrongly-triggered automation system as pilots wrestled to regain control.
Tjahjono said it was too early to draw any conclusions from the Ethiopian report or determine any links between the crashes because it contained factual data without analysis.
“We have already observed some similarities…but we cannot determine them exactly until after our investigators go to Ethiopia when we will conduct a joint investigation,” he said.
The two Indonesian investigators would sign an agreement on their role under an International Civil Aviation Organisation (ICAO) protocol, he said.
A preliminary report into the crash of the Lion Air 737 MAX in Indonesia suggested pilots lost control after grappling with the MCAS software, a new automated anti-stall feature that repeatedly lowered the nose based on a faulty sensor data.
Securing safety of MAX planes
Meanwhile, the Civil Aviation Authority of Singapore on Friday said that it would participate in a technical review panel on the Boeing Co 737 MAX jet led by the U.S. Federal Aviation Administration (FAA).
The FAA said on Wednesday that it is forming an international team to review the safety of the Boeing 737 MAX, which was grounded after two fatal crashes since October.
Boeing boss speaks on accidents
Following the release of a preliminary report on the ET302 crash, Boeing issued its response on Thursday in a statement that admitted technical errors whiles promising a robust series of steps going forward.
The statement posted on its website was signed by its Chairman, president and CEO , Dennis Muilenburg.
“The full details of what happened in the two accidents will be issued by the government authorities in the final reports, but, with the release of the preliminary report of the Ethiopian Airlines Flight 302 accident investigation, it’s apparent that in both flights the Maneuvering Characteristics Augmentation System, known as MCAS, activated in response to erroneous angle of attack information.
“The history of our industry shows most accidents are caused by a chain of events. This again is the case here, and we know we can break one of those chain links in these two accidents.
“As pilots have told us, erroneous activation of the MCAS function can add to what is already a high workload environment. It’s our responsibility to eliminate this risk. We own it and we know how to do it,” he said in part.Watch video and full transcript of Boeing CEO’s address

Preliminary report expected today, April 4
Investigators will release on Thursday a keenly awaited report on the deadly crash of an Ethiopian Airlines jet, Ethiopia’s Transport Ministry said, giving the first official clues to the second crash of a new Boeing 737 MAX in five months.
“The 10:30 a.m. (0730 GMT) press conference is to present the preliminary report,” Ethiopian Transport Ministry spokesman Musie Yehyies said.
The report may shed light on how a piece of cockpit software came back to life after pilots initially switched it off as they tried to save the doomed jet, people familiar with the matter said, placing both technology and crew in the spotlight.
Some 35 nationalities were among the 157 passengers and crew who died when the nearly full plane crashed six minutes after take-off from Addis Ababa, the Ethiopian capital, in clear conditions.
The March 10 disaster prompted a worldwide grounding of Boeing’s best-selling plane and scrutiny of its certification process.

Pilots followed Boeing’s instructions to the latter
The Wall Street Journal has reported what it says are crucial information from the flight recorder – black box – analysis of the ill-fated Ethiopian ET302 crash.
The latest details said pilots in charge of the Boeing Co. 737 MAX initially followed emergency procedures laid out by the plane maker but still failed to recover control of the jet.
Sources close to the probe said after turning off a flight-control system that was automatically pushing down the plane’s nose shortly after takeoff March 10, the crew couldn’t get the aircraft to maintain its balance till it crashed.
The disclosure of initial findings have been the subject of a ping-pong with Airline officials denying comments on it last week. Government officials also announced an imminent report release on Monday only to backtrack.
SEATTLE/PARIS, April 3 (— Maggie Fick (MaggieFick) April 3, 2019
Reuters) - Boeing anti-stall software on a doomed Ethiopian Airlines jet re-engaged as many as four times after the crew initially turned it off due to suspect data from an airflow sensor, two people familiar with the matter said.
Preliminary report no-show, FAA to grill Boeing software
Authorities in Ethiopia flip-flopped on an earlier report on Monday that it was due to release a preliminary report on the ET302 crash. “Not today, maybe this week,” the source said, when asked about the report.
Incidentally this Reuters source was from the Transport Ministry which is leading the team probing the incident.
A Foreign Affairs Ministry official was cited for the initial information that the report was due to be released Monday. Nebiat Getachew was widely quoted with Bloomberg adding that embattled plane maker Boeing said it was reviewing the report.
Meanwhile the United States aviation regulator, the Federal Aviation Administration, FAA; says it was waiting to receive final package of Boeing’s software enhancement over the coming weeks.
FAA said in a statement: “Time is needed for Boeing to as the result of an ongoing review of the 737 MAX flight control system to ensure that Boeing has identified and appropriately addressed all pertinent issues.
Upon receipt, the FAA will subject Boeing’s completed submission to a rigorous safety review. The FAA not approve the software for installation until the agency is satisfied with the submission.”
The plane maker last week announced a software upgrade and invited its clients to a meeting over the issue. The meeting was however poorly attended with Ethiopian opting out.
Preliminary report expected today, April 1
Reports from Addis Ababa indicate that a preliminary report from the March 1 crash in Bishoftu is expected today, three weeks after the incident which claimed 157 people.
The Bloomberg news portal quoted a Foreign Ministry official, Nebiat Getachew, as confirming the information. Embattled plane maker Boeing said it was reviewing the report.
The airline had last week disputed a news item that said its CEO had hinted that a report of the ET302 flight was due last week or earliest this week.
Ethiopian said at the time that in keeping with international standards, it was waiting for the result as all concerned parties and cautioned against irresponsible reportage.
“We, at Ethiopian strongly refutes recent reports which state that Ethiopian GCEO expected the preliminary release of a report into the March 10 crash of its Boeing 737-8 MAX “maybe this week or next week”.
Ethiopian GCEO did not say anything about the time the investigation report will be released,” the said in a statement.
Boeing has been under pressure as results are being awaited. Its 737 Max 8 jets have been grounded globally with its shares plumetting on the stock market.
Two key findings from the probe indicates that there were similarities between the March 10 crash and an October 2018 incident that involved Indonesian flier Lion Air.
Late last week, the Wall Street Journal, WSJ, reported that the plane’s Maneuvering Characteristics Augmentation System (MCAS), a new anti-stall mechanism was activated at the time of the crash.
The newspaper said the preliminary findings from the “black box” recorders were subject to revisions. The plane crashed on March 10 shortly after take off from Addis Ababa en route to Nairobi, Kenya.
Investigators into the Lion Air incident have also focused on the new anti-stall system. Boeing last Wednesday said a planned software fix would prevent repeated operation of the system that is at the centre of safety concerns.
“Pitch up, pitch up” last words of worried pilot
Three weeks after the March 10 crash that claimed the lives of all 157 people on board, leaked details have indicated the final words by one of the pilots on the aircraft.
One pilot, according to the Wall Street Journal, said to the other “pitch up, pitch up!” before their radio died. It is believed that these words were contained on the flight recorder – black box.
Amid an eagerly awaited preliminary report; an anti-stalling system on the Boeing 737 Max, has been blamed for the disaste.
The plane had taken-off – and was only 450ft (137m) above the ground – when its nose began to pitch down. It crashed six minutes into the journey in the town of Bishoftu.
Boeing’s anti-stall system activated before crash – WSJ
Investigators into a Boeing 737 MAX crash in Ethiopia that killed 157 people have reached a preliminary conclusion that an anti-stall system was activated before the plane hit the ground, the Wall Street Journal reported on Friday, citing people briefed on the matter.
The newspaper said the preliminary findings from the “black box” recorders were subject to revisions, adding a preliminary report from Ethiopian investigators was expected within days.
The plane crashed on March 10 shortly after take off from Addis Ababa.
Investigators into a deadly 737 MAX crash in Indonesia in October have also focused on the new anti-stall system, called MCAS. Boeing on Wednesday said a planned software fix would prevent repeated operation of the system that is at the centre of safety concerns.
Boeing’s fastest-selling 737 MAX jet, with orders worth more than $500 billion at list prices, has been grounded globally by the Federal Aviation Administration (FAA), although airlines are still allowed to fly them without passengers to move planes to other airports.
Boeing sued in U.S. by Rwandan kids
A lawsuit against Boeing Co was filed in U.S. federal court on Thursday in what appeared to be the first suit over a March 10 Ethiopian Airlines 737 MAX crash that killed 157 people.
The lawsuit was filed in Chicago federal court by the family of Jackson Musoni, a citizen of Rwanda, and alleges that Boeing, which manufactures the 737 MAX, had defectively designed the automated flight control system.
Wednesday’s complaint was filed by Musoni’s three minor children, who are Dutch citizens residing in Belgium.
Boeing did not immediately respond to a request for comment on the lawsuit.
The 737 MAX planes were grounded worldwide following the Ethiopian Airlines disaster, which came five months after a Lion Air crash in Indonesia that killed 189 people.
Boeing said on Wednesday it had reprogrammed software on its 737 MAX to prevent erroneous data from triggering an anti-stall system that is facing mounting scrutiny in the wake of two deadly nose-down crashes in the past five months.
The planemaker said the anti-stall system, which is believed to have repeatedly forced the nose lower in at least one of the accidents, in Indonesia last October, would only do so once per event after sensing a problem, giving pilots more control.
The crash of Boeing’s passenger jet in Ethiopia raised the chances that families of the victims, even non-U.S. residents, will be able to sue in U.S. courts, where payouts are much larger than in other countries, some legal experts have said.
The lawsuit says Boeing failed to warn the public, airlines and pilots of the airplane’s allegedly erroneous sensors, causing the aircraft to dive automatically and uncontrollably.
Boeing unveils software fix to 737 MAX
Embattled aviation giant Boeing pledged Wednesday to do all it can to prevent crashes like two that killed nearly 350 people in recent months, as it unveiled a fix to the flight software of its grounded 737 MAX aircraft.
Boeing gathered hundreds of pilots and reporters to unveil the changes to the MCAS stall prevention system, which has been implicated in the crashes in Ethiopia and Indonesia, as part of a charm offensive to restore the company’s reputation.
“We are going to do everything to make sure that accidents like this don’t happen again,” Mike Sinnett, Boeing’s vice president of product strategy, told reporters at a factory in Washington state.
Sinnett said were developed “after months of testing and hundreds of hours” — at the company’s massive factory in Renton, Washington.
The MCAS, which lowers the aircraft’s nose if it detects a stall or loss of airspeed, was developed specifically for the 737 MAX, which has heavier engines than its predecessor.
Among the changes, the MCAS will no longer repeatedly make corrections when the pilot tries to regain control, and will automatically disconnect in the event of disagreements between the two “angle of attack” (AOA) sensors, the company said.
The initial investigation into the October Lion Air crash in Indonesia, which killed all 189 people on board, found that one of the AOA sensors failed but continued to transmit erroneous information to the MCAS.
Boeing also will install a warning feature — at no cost —- called a “disagree light” to indicate to the pilot when the left and right AOA sensors are out of sync.
The company also is revising pilot training, including for those already certified on the 737, to provide “enhanced understanding of the 737 MAX” flight system and crew procedures.
