JAKARTA/SINGAPORE/PARIS (Reuters) – The pilots of a doomed Lion Air Boeing 737 MAX scoured a handbook as they struggled to understand why the jet was lurching downwards, but ran out of time before it hit the water, three people with knowledge of the cockpit voice recorder contents said.

The investigation into the crash, which killed all 189 people on board in October, has taken on new relevance as the U.S. Federal Aviation Administration (FAA) and other regulators grounded the model last week after a second deadly accident in Ethiopia.

Investigators examining the Indonesian crash are considering how a computer ordered the plane to dive in response to data from a faulty sensor and whether the pilots had enough training to respond appropriately to the emergency, among other factors.

It is the first time the voice recorder contents from the Lion Air flight have been made public. The three sources discussed them on condition of anonymity.

Reuters did not have access to the recording or transcript.

A Lion Air spokesman said all data and information had been given to investigators and declined to comment further.

The captain was at the controls of Lion Air flight JT610 when the nearly new jet took off from Jakarta, and the first officer was handling the radio, according to a preliminary report issued in November.

Just two minutes into the flight, the first officer reported a “flight control problem” to air traffic control and said the pilots intended to maintain an altitude of 5,000 feet, the November report said.

The first officer did not specify the problem, but one source said airspeed was mentioned on the cockpit voice recording, and a second source said an indicator showed a problem on the captain’s display but not the first officer’s.

The captain asked the first officer to check the quick reference handbook, which contains checklists for abnormal events, the first source said.

For the next nine minutes, the jet warned pilots it was in a stall and pushed the nose down in response, the report showed. A stall is when the airflow over a plane’s wings is too weak to generate lift and keep it flying.

The captain fought to climb, but the computer, still incorrectly sensing a stall, continued to push the nose down using the plane’s trim system. Normally, trim adjusts an aircraft’s control surfaces to ensure it flies straight and level.

“They didn’t seem to know the trim was moving down,” the third source said. “They thought only about airspeed and altitude. That was the only thing they talked about.”

Boeing Co declined to comment on Wednesday because the investigation was ongoing.

The manufacturer has said there is a documented procedure to handle the situation. A different crew on the same plane the evening before encountered the same problem but solved it after running through three checklists, according to the November report.

But they did not pass on all of the information about the problems they encountered to the next crew, the report said.

The pilots of JT610 remained calm for most of the flight, the three sources said. Near the end, the captain asked the first officer to fly while he checked the manual for a solution.

About one minute before the plane disappeared from radar, the captain asked air traffic control to clear other traffic below 3,000 feet and requested an altitude of “five thou”, or 5,000 feet, which was approved, the preliminary report said.

As the 31-year-old captain tried in vain to find the right procedure in the handbook, the 41-year-old first officer was unable to control the plane, two of the sources said.

The flight data recorder shows the final control column inputs from the first officer were weaker than the ones made earlier by the captain.

“It is like a test where there are 100 questions and when the time is up you have only answered 75,” the third source said. “So you panic. It is a time-out condition.”

The Indian-born captain was silent at the end, all three sources said, while the Indonesian first officer said “Allahu Akbar”, or “God is greatest”, a common Arabic phrase in the majority-Muslim country that can be used to express excitement, shock, praise or distress.

The plane then hit the water, killing all 189 people on board.

French air accident investigation agency BEA said on Tuesday the flight data recorder in the Ethiopian crash that killed 157 people showed “clear similarities” to the Lion Air disaster. Since the Lion Air crash, Boeing has been pursuing a software upgrade to change how much authority is given to the Maneuvering Characteristics Augmentation System, or MCAS, a new anti-stall system developed for the 737 MAX.

The cause of the Lion Air crash has not been determined, but the preliminary report mentioned the Boeing system, a faulty, recently replaced sensor and the airline’s maintenance and training.

On the same aircraft the evening before the crash, a captain at Lion Air’s full-service sister carrier, Batik Air, was riding along in the cockpit and solved the similar flight control problems, two of the sources said. His presence on that flight, first reported by Bloomberg, was not disclosed in the preliminary report.

The report also did not include data from the cockpit voice recorder, which was not recovered from the ocean floor until January.

Soerjanto Tjahjono, head of Indonesian investigation agency KNKT, said last week the report could be released in July or August as authorities attempted to speed up the inquiry in the wake of the Ethiopian crash.

On Wednesday, he declined to comment on the cockpit voice recorder contents, saying they had not been made public.

Ethiopian crash crew’s voices could unlock high-stakes Boeing inquiry

ADDIS ABABA/PARIS (Reuters) – The investigation into the final minutes of Ethiopian Airlines Flight 302 turned on Tuesday to the secrets in the cockpit voice recorder as Boeing and a shaken global aviation industry hung on the outcome.

The voices of Captain Yared Getachew and First Officer Ahmednur Mohammed could reveal what led to the March 10 crash of the Boeing 737 MAX that has worrying parallels with another disaster involving the same model off Indonesia in October.

The twin disasters killed 346 people.

Black box data was downloaded in France but only Ethiopian experts leading the probe have heard the dialogue between Getachew, 29, and Mohammed, 25. The data was back in Addis Ababa on Tuesday, sources familiar with the probe told Reuters.

Experts believe a new automated system in Boeing’s flagship MAX fleet – intended to stop stalling by dipping the plane’s nose – may have played a role in both crashes, with pilots unable to override it as their jets plunged downwards.

Both came down just minutes after take-off after erratic flight patterns and loss of control reported by the pilots. However, every accident is a unique chain of human and technical factors, experts say.

The prestige of Ethiopian Airlines, one of Africa’s most successful companies, and Boeing, the world’s biggest planemaker and a massive U.S. exporter, is at stake in the inquiry.

AWKWARD QUESTIONS FOR INDUSTRY

Lawmakers and safety experts are questioning how thoroughly regulators vetted the MAX model and how well pilots were trained on new features. For now, regulators have grounded the existing fleet of more than 300 MAX aircraft and deliveries of nearly 5,000 more – worth well over $500 billion – are on hold.

Pressure on the Chicago-headquartered company has grown with news that federal prosecutors and the U.S. Department of Transportation are scrutinizing how carefully the MAX model was developed, two people briefed on the matter said.

The U.S. Justice Department was looking at the Federal Aviation Administration’s (FAA) oversight of Boeing, one of the people said. And a federal grand jury last week issued at least one subpoena to an entity involved in the plane’s development.

In the hope of getting its MAX line back into the air soon, Boeing said it will roll out a software update and revise pilot training. In the case of the Lion Air crash in Indonesia, it has raised questions about whether crew used the correct procedures.

“Lives depend on the work we do,” acknowledged Boeing boss Dennis Muilenburg, facing the biggest crisis of his tenure.

The MAX, which offers cost savings of about 15 percent on fuel, was developed for service from 2017 after the successful launch by its main rival of the Airbus A320neo.

After Ethiopia, France and the United States all noted parallels with the Indonesia crash, one person familiar with the probe said black box data showed the Ethiopian Airlines jet’s “angle of attack” was “very similar” to the Lion Air plane.

The angle of attack is a fundamental parameter of flight, measuring the degrees between the air flow and the wing. If it is too high, it can throw the plane into an aerodynamic stall.

GLOBAL RAMIFICATIONS

In the hot seat over its certification of the MAX without demanding additional training and its closeness to Boeing, the FAA has said it is “absolutely” confident in its vetting.

But given the U.S. probe, Canada said it would re-examine its acceptance of the FAA validation and do its own independent certification.

The crisis has put the airline world in a spin.

One company, Norwegian Airlines, has already said it will seek compensation after grounding its MAX aircraft.

Various firms are reconsidering Boeing orders, and some airlines are revising profit forecasts given they now cannot count on maintenance and fuel savings factored in from the MAX.

Beyond the corporate ramifications, anguished relatives are still waiting to find out what happened.

Many have been visiting the crash site in a charred field to seek some closure, but there is anger at the slow pace of information and all they have been given for funerals is earth.

Abdulmajid Shariff, a Yemeni who lost his brother-in-law, was heading home on Tuesday. “I’m just so terribly sad. I had to leave here without the body of my dead brother. But I have to praise almighty God, there is nothing more to do.”

Boeing black box review begins in France, aviation world waits

PARIS/ADDIS ABABA (Reuters) – Investigators in France on Friday examined the black boxes of a Boeing 737 MAX that crashed in Ethiopia, as a spooked global airline industry waited to see if the cause was similar to a disaster in Indonesia months before.

Ethiopian Airlines flight 302 crashed soon after take-off from Addis Ababa last weekend, killing 157 people, the second such calamity involving Boeing’s flagship new model after a jet came down off Indonesia in October with 189 people on board.

In both cases, pilots asked to return minutes into flight.

The international repercussions are huge. Regulators have grounded the 737 MAX around the world, and the U.S. planemaker has halted next deliveries of the several thousand planes on order for a model intended to be the future industry workhorse.

Parallels between the twin disasters have frightened travelers worldwide and wiped almost $28 billion off Boeing’s stock market value.

U.S. aviation authorities say information from the wreckage in Ethiopia plus newly-refined data about its flight path indicated some similarities.

Two sources said investigators retrieved from the wreckage a piece of a stabilizer, which moves the nose up and down, that was set in an unusual position – one similar to that of the Lion Air plane that crashed in Indonesia.

 

“NOSE-DIVE”

Pilots were waiting anxiously for the investigation.

“Looking at the crash site photos, the aircraft appears to have nose-dived,” Paul Gichinga, former head of the Kenya Airline Pilots Association, told Reuters.

“The pilot must have gotten some sort of indication that maybe the airspeed was unreliable or something and decided, instead of climbing and going to sort out the problem up there, the best thing was to return to have it sorted.”

Boeing, the world’s biggest planemaker, has said the 737 MAX is safe, though it plans to roll out a software upgrade in the coming weeks. It continued to produce at full speed at its factory near Seattle, but paused shipments.

French authorities have possession of the flight data and cockpit voice recorders, though Ethiopia is formally leading the investigation and U.S. experts are in Paris and Addis Ababa too.

First conclusions could take several days.

The New York Times said the Ethiopian captain, Yared Getachew, initially reported a “flight control” problem in a calm voice before asking to return in panicked tones three minutes into the flight. “Break break, request back to home,” he told controllers, the newspaper reported, citing a person who had reviewed the communications.

The jet initially flew below the minimum safe height for its climb, then once at higher altitude was oscillating up and down by hundreds of feet, all at abnormal speed, the Times said. It then disappeared from radar over a restricted military zone and lost contact with air controllers five minutes after take-off.

FAMILIES “STUCK AND EMOTIONAL”

In Ethiopia, grieving relatives have been visiting the charred and debris-strewn field where the jet came down to pay last respects. Only fragments remain, meaning it may take weeks or months to identify all the victims who came from 35 nations.

Some families stormed out of a meeting with Ethiopian Airlines on Thursday complaining about lack of information.

Israeli Ilan Matsliah flew to Ethiopia hours after confirming his brother was on board, thinking it would be quick to find remains for burial in accordance with Jewish tradition.

“More than 24 hours is a problem for us. But I have been here for more than 96 hours,” the 46-year old told Reuters.

“We are now stuck in the same place, the same as Monday. We are very emotional.”

With heightened global scrutiny, the head of Indonesia’s transport safety committee said a report into the Lion Air crash would be speeded up for release in July or August.

A preliminary report focused on maintenance, training and the response of a Boeing anti-stall system to a recently replaced sensor.

As the ripple-effect from the Ethiopia crash spread, Canada’s biggest carrier Air Canada suspended financial forecasts for the first quarter and the year, two days after its MAX jets were grounded. It had expected the MAX to deliver significant savings on fuel and maintenance costs.

A potential new Chinese order for more than 100 jets worth well over $10 billion was thrown into doubt.

Legal experts said even non-U.S. families of the Ethiopia victims may be able to sue Chicago-based Boeing in the United States – where payouts are larger – as eight of the dead were American and plaintiffs may argue liability hinges on system design and safety decisions made by executives.

Boeing, one of the biggest companies by market capitalization on the Dow Jones and a darling of the market, has seen its shares lose 13 percent since the crash.

Its shares had hit record highs just a week before, having risen a stunning 52 percent since the end of December, and were still up 19 percent year-to-date.

Indonesian divers find crashed Lion Air jet’s second black box

JAKARTA (Reuters) – Indonesian authorities on Monday said they will immediately begin to download contents of a cockpit voice recorder (CVR) from a Lion Air jet that crashed into the sea near Jakarta more than two months ago, killing all 189 people on board.

The crash was the world’s first of a Boeing Co 737 MAX jet and the deadliest of 2018, and the recovery of the aircraft’s second black box from the Java Sea north of Jakarta on Monday may provide an account of the last actions of the doomed jet’s pilots.

“We have our own laboratory and personnel to do it,” Haryo Satmiko, deputy chief of the transportation safety committee, told Reuters.

Satmiko said it had in the past taken up to three months to download, analyze and transcribe the contents of recorders.

Contact with flight JT610 was lost 13 minutes after it took off on Oct. 29 from the capital, Jakarta, heading north to the tin-mining town of Pangkal Pinang.

A preliminary report by Indonesia’s transport safety commission focused on airline maintenance and training, as well as the response of a Boeing anti-stall system and a recently replaced sensor, but did not give a cause for the crash.

A group of relatives of victims urged the transportation safety committee to reveal “everything that was recorded” and to work independently.

Navy Lieutenant Colonel Agung Nugroho told Reuters a weak signal from the recorder was detected several days ago and it was found buried deep in soft mud on the seafloor in water about 30 meters (98 ft) deep.

“We don’t know what damage there is but it has obvious scratches on it,” Nugroho said.

Pictures supplied by an official from the transportation agency showed chipped bright orange paint on the CVR memory unit, but no major dents.

Nurcahyo Utomo, an investigator at the safety committee, told reporters it should take no more than five days to download the data, but if there was a problem the CVR would be sent to the manufacturer.

“We hope it can be done as soon as possible because all the Boeing operators are waiting,” said Utomo, adding that investigators hoped to complete the full report within a year of the crash.

With the recovery of the CVR, officials said there was no plan to continue searching for other parts of the wrecked plane, including an angle of attack sensor that was suspected to have been faulty.

The navy’s Nugroho said human remains had been found near the location of the CVR, about 50 meters from where the crashed jet’s other black box, the flight data recorder (FDR), was found three days after the crash.

Investigators brought in a navy ship last week after a 10-day, 38 billion rupiah ($2.70 million), an effort funded by Lion Air failed to find the recorder. Bureaucratic wrangling and funding problems hampered the initial search.

The L3 Technologies Inc CVR was designed to send acoustic pings for 90 days after a crash in water, according to an online brochure from the manufacturer.

That would mean that after Jan. 27, investigators could have faced a far bigger problem in finding the CVR buried along with much of the wreckage deep in mud on the sea floor..

Boeing said in a statement on Monday that it was taking “every measure” to fully support this investigation.

“As the investigation continues, Boeing is working closely with the U.S. National Transportation Safety Board as a technical advisor to support Indonesia’s National Transportation Safety Committee,” the planemaker said in a statement.

Since the crash, Lion Air has faced scrutiny over its maintenance and training standards, and relatives of victims have filed at least three lawsuits against Boeing.

Indonesia struggles with damaged black box from crashed jet, hunts for second

JAKARTA (Reuters) – Indonesian divers hunted on Friday for a second black box from an aircraft that crashed into the sea this week with the loss of all 189 people on board, as investigators tried to get data from a partly damaged recorder already found.

The Lion Air Boeing Co 737 MAX, which only went into service in August, crashed on Monday into the Java Sea.

Air traffic control lost contact with it 13 minutes after it took off from the capital, Jakarta, heading north to the tin-mining town of Pangkal Pinang.

Searchers have found one black box and just one passenger has been identified from partial human remains recovered from the shallow waters.

“We haven’t downloaded the data because there are some broken parts in the black box,” Haryo Satmiko, the deputy of the transport safety panel, said of the flight data recorder found on Thursday, adding that some of the damage was to a socket on the device.

Satimiko told Reuters investigators were awaiting advice from the U.S. National Transportation Safety Board or Boeing.

The pilot of flight JT610 had asked for, and received, permission to turn back to Jakarta airport, but what went wrong remains a mystery.

Efforts are now focused on retrieving the second of the two black boxes, as the cockpit voice recorder and the flight data recorder are known, the head of Indonesia’s transport safety committee said.

“The team have been hearing the ‘ping’ sound from another black box for two days,” Soerjanto Tjahjono told Reuters.

The sea is only 30 m (98 ft) deep at the crash site but strong currents and nearby energy pipelines have hampered the search for the aircraft operated by the budget carrier.

While victims’ relatives are desperate to know what happened, the investigation of the first crash of a Boeing 737 MAX is also the focus of scrutiny by the global aviation industry.

‘WORK FAST’

Investigators said the damage suffered by the first data device reflected the severity of the impact.

Downloading the data on flight recorders can take as little as two hours but analyzing it can take weeks.

Results of a preliminary investigation will be made public after 30 days, one official on the investigation team said.

President Joko Widodo, visiting the search operation’s headquarters at Jakarta’s port, thanked rescue officials and the military involved and appealed for them to step up the search.

“I ask for you to use all your might, all the technology available, to work fast to find anything else,” he said.

He said he wanted investigators to determine the cause of the crash quickly so “we can determine the next step”.

Relatives of the missing have been looking through personal items recovered from the sea including rows of shoes, backpacks and wallets.

Television footage showed an aircraft wheel being hoisted from the sea on Friday and a diver holding a piece of what appeared to be part of the fuselage bearing the Lion Air logo.

The search and rescue agency said that 65 body bags with human remains had been taken to a police hospital where forensic doctors have been trying to identify victims.

Doctors have been taking DNA samples from relatives.

Indonesia is one of the world’s fastest-growing aviation markets but its safety record has been patchy. Its transport safety panel investigated 137 serious aviation incidents from 2012 to 2017.

JAKARTA (Reuters) – Indonesian authorities on Thursday retrieved a flight data recorder from a Lion Air jet that crashed and broke apart in shallow sea near the capital, Jakarta, this week, killing all 189 people on board.

The country’s second-deadliest air disaster since 1997 has prompted renewed concern about Indonesia’s patchy aviation safety record, and the government has said Lion Air will face tougher safety regulation.

Investigations into the world’s first crash of a Boeing Co 737 MAX, introduced into commercial service last year, will be scrutinized by the global aviation industry.

“Hopefully, this can unveil the mystery behind the plane crash,” Indonesia’s transportation safety committee chief Soerjanto Tjahjono told a news conference at Jakarta’s main port after receiving the device, known as a black box.

The data it holds should provide clues to what went wrong with the plane, which had only been in service since August.

It lost contact with ground staff just 13 minutes after taking off early on Monday from Jakarta, on its way to the tin-mining town of Pangkal Pinang.

The pilot had asked to return to base shortly after take-off, and ground control officials had approved the request.

A navy diver told broadcaster Metro TV on board a search vessel his team found the orange-colored box intact in debris on the muddy seafloor.

Indonesia’s transportation safety committee (KNKT) will analyze its data in Jakarta, which could take up to two weeks.

Searchers have yet to find the second black box containing recordings of cockpit conversations. Strong currents have hampered search efforts, complicated by the presence of energy pipelines in the area.

The discovery of the black box may provide some relief to grieving relatives. But hopes are fading of finding a large section of fuselage intact with bodies, easily retrievable, inside.

The commander of the navy divers involved in the search was quoted by the Kompas.com news portal as saying divers had found many bodies. But only one has been identified.

“What is important for us is to get more information about the victims because having their remains back is important for us so we can bury them properly,” said Ade Inyo, whose brother in law was on the flight.

MORE INSPECTIONS, SAFETY REVIEW

The investigation will be carried out with help from Boeing, General Electric and the Federal Aviation Federation, officials have said.

It will also focus on four of Lion Air’s staff including its technical director who were suspended by Indonesia’s transportation ministry on Wednesday amid speculation the aircraft was not airworthy.

“For now, we will focus on two primary causes,” KNKT deputy chief Haryo Satmiko told Reuters, referring to equipment and the people who flew, maintained and managed the aircraft.

The transport ministry suspended for 120 days Lion Air’s maintenance and engineering director, fleet maintenance manager and the release engineer who gave the jet permission to fly on Monday, it said in a press release.

Founded in 1999, the privately owned budget carrier’s aircraft have been involved in at least 15 safety incidents and it has faced tougher international safety restrictions than other Indonesian airlines.

It will now be subjected to more intensive “on-ramp” inspections compared with other airlines, authorities said.

President Joko Widodo has also ordered a review of all regulations relating to flight safety.

Indonesia is one of the world’s fastest-growing aviation markets. Its transportation safety committee investigated 137 serious aviation incidents from 2012 to 2017.

Lion Air said the aircraft that crashed had been airworthy and the pilot and co-pilot had 11,000 hours of flying time between them.

But according to the transport safety committee, the plane had technical problems on its previous flight on Sunday, from the city of Denpasar on the resort island of Bali, including an issue over “unreliable airspeed”.

Lion Air chief executive Edward Sirait has acknowledged reports of technical problems with the aircraft but said maintenance had been carried out “according to procedure” before it was cleared to fly again.

Lion Air’s only other fatal accident was in 2004 when an MD-82 crashed upon landing at Solo City, killing 25 of the 163 people on board, according to the Flight Safety Foundation’s Aviation Safety Network.

In April, the airline announced a firm order to buy 50 Boeing 737 MAX 10 narrowbody jets with a list price of $6.24 billion. It is one of the U.S. planemaker’s largest customers globally and was the first carrier globally to take delivery of the 737 MAX last year.
