Most of the airlines flying Boeing’s 737 MAX 8 – the model that has crashed twice in the past six months, including Sunday’s Ethiopian Airlines disaster – are continuing to use the jet, including major U.S. airlines.

China and Indonesia, as well as a few airlines in other countries, have grounded their MAX 8 fleets, however. India’s air safety regulator said Monday it is ordering a review of the MAX.

The U.S. Federal Aviation Administration said Monday afternoon it plans to issue a “continued airworthiness notification” for the MAX jet. It is collecting data on the crash and has a team on the ground in Ethiopia along with the National Transportation Safety Board, the agency said. “If we identify an issue that affects safety, the FAA will take immediate and appropriate action,” it said on Twitter.

The Renton-built 737 MAX is Boeing’s best-selling plane, and the company has been delivering the newer MAX 8 model since May 2017.

In October, a MAX 8 operated by Lion Air crashed in the Java Sea, killing 189 people on board. Then on Sunday, a MAX 8 operated by Ethiopian Airlines crashed in Addis Ababa, Ethiopia, killing all 157 people on board. Both were new planes that crashed shortly after takeoff, though it’s not yet clear if there might be any link between the two crashes.

Airlines have ordered more than 5,000 of the jets, but just 350 of those have been delivered, according to data compiled by The Associated Press.

Southwest Airlines has 31 of the planes delivered, American Airlines and GECAS have 22 and Air Canada has 20. Norwegian Air Shuttle has 18; China Southern Airlines has 16; Air China, Air Lease Corp, Flydubai and Lion Air all have 14 each; China Eastern Airlines has 13; and United Airlines and WestJet have 12 each.

SeaTac-based Alaska Airlines doesn’t have any operating now but has ordered 32 of the jets.

Regulators in China and Indonesia have grounded their nations’ MAX 8 aircraft in the wake of Sunday’s crash.

The other airlines that have at least temporarily halted MAX 8 flights include Ethiopian Airlines, Cayman Airways and Comair. In all, 23 airlines have grounded the aircraft model, mostly in China.

The two American airlines with the most MAX 8s – Southwest and American airlines – issued statements to CNN saying they would continue to fly the MAX 8.

“We remain confident in the safety and airworthiness of our fleet of more than 750 Boeing aircraft,” the Southwest statement said. American said it has “full confidence in the aircraft.”

Other airlines continuing to stand behind the MAX 8 include Norwegian Airlines, TUI Aviation, Silk Air, Fiji Airways, Icelandair, Flydubai, WestJet, GOL Linhas Aereas.

Here’s a full list of which airlines have MAX jets in their fleet and which have them on order. </s> SINGAPORE — A growing number of airlines and countries around the world have grounded Boeing 737 MAX jets or banned them from their airspace following the crash of an Ethiopian Airlines plane that killed 157 people on Sunday, five months after a similar Indonesian Lion Air jet plunged into the ocean, killing 189. A look at those countries and airlines:

Australia has announced a temporary ban on flights by 737 MAX aircraft, although none of its airlines currently operate them. The Civil Aviation Safety Authority said Tuesday that the ban will affect two foreign airlines — SilkAir and Fiji Airways — that use them for flights to Australia. The authority said Singapore’s SilkAir has already grounded its 737 MAX jets, and that it is working with regulators there and in Fiji to minimize disruptions. It said that Fiji Airways has two 737 MAX 8 jets in its fleet. Fiji Airways and Fiji’s Civil Aviation Authority said they would ground the fleet until more information is known about the cause of the Ethiopian Airlines accident.

Brazil’s Gol Airlines has suspended the use of seven Max 8 jets. The airline said it is following the investigation closely and hopes to return the aircraft to use as soon as possible. Gol said it has made nearly 3,000 flights with the Max 8, which went into service last June, with “total security and efficiency.”

Canadian charter airline Sunwing has suspended use of its four 737 MAX 8 planes. Canadian Transport Minister Marc Garneau said he has no plans to ground Canada’s fleet of 737 MAX aircraft, but that “all options are on the table.”

Cayman Airways, a Caribbean carrier, has stopped using its two Max 8 jets. President and CEO Fabian Whorms said the move starting Monday will cause changes to flight schedules. Cayman is the flag carrier of Cayman Islands, a British overseas territory.

China has 96 Max 8 jets in service, belonging to carriers such as Air China, China Eastern Airlines and China Southern Airlines. The Civil Aviation Authority directed the planes to be grounded indefinitely on Monday. It said the order was “taken in line with the management principle of zero tolerance for security risks.” There were eight Chinese citizens on the Ethiopian Airlines flight that crashed shortly after taking off on Sunday. The authority said it will consult the U.S. Federal Aviation Administration and Boeing before deciding when to lift the ban.

A spokesman for Ethiopian Airlines said it grounded its remaining four Max 8 jets as an “extra safety precaution” while it investigates Sunday’s deadly crash. The airline is awaiting the delivery of 25 more Max 8 jets.

The European Aviation Safety Agency has issued a directive grounding all 737 MAX 8 and Max 9 aircraft. EASA said in its emergency airworthiness directive Tuesday that “at this early stage” of the most recent investigation, “it cannot be excluded that similar causes may have contributed to both events.” It said “based on all available information, EASA considers that further actions may be necessary to ensure the continued airworthiness of the two affected models.” It said companies may make one noncommercial flight to return their planes to a location where they can be inspected. The grounding applies to all European Union airspace.

Fiji has suspended all Max 8 flights in and out of the country. The decision only affects one operator, Fiji Airways.

Hong Kong has banned the operation of all 737 MAX aircraft “into, out of and over” the key Asian aviation hub beginning Wednesday evening. The announcement from the Civil Aviation Department said the ban would continue “until further notice.” It said the department has been in close contact with the FAA and other the relevant organizations, including the two airlines, SpiceJet of India and Russia’s Globus Airlines, that use the aircraft to operate flights into and out of Hong Kong International Airport.

Icelandair Group has temporarily suspended operations of its three 737 MAX aircraft until further notice. President and CEO Bogi Nels Bogason said Tuesday that the company will follow developments closely and work with local, European and U.S. authorities on any steps that need to be taken. He said the temporary suspension won’t impact the company’s operations, as it only affects three aircraft out of a fleet of 33.

India has grounded all 737 MAX 8 planes. A statement late Tuesday said the planes “will be grounded till appropriate modifications and safety measures are undertaken to ensure their safe operations.” The statement did not say how many planes were affected.

Indonesia has temporarily grounded Max 8 jets to inspect their airworthiness. Director General of Air Transportation Polana B. Pramesti said the move was made to ensure flight safety. A Lion Air model of the same plane crashed in Indonesia in October. Indonesian airlines operate 11 Max 8 jets. Lion Air, which owns 10 of them, said it will try to minimize the impact of the decision on operations. The other Max 8 jet belongs to national carrier Garuda.

New Zealand has suspended Max 8 flights in and out of the country. The decision only affects one operator, Fiji Airways. No New Zealand airlines use the Max 8 planes.

The Civil Aviation Authority said no Malaysian carriers operate the Max 8, but that foreign airlines are banned from flying the plane in Malaysia, and from transiting in the country, until further notice.

Mexican airline Aeromexico has suspended flights of its six Max 8 jets. Aeromexico said it “fully” trusts the safety of its fleet but ordered the grounding to ensure “the safety of its operations and the peace of mind of its customers.” It said other planes will take over the routes usually flown by the Max 8.

Oman and the United Arab Emirates have barred flights by Max 8 and Max 9 aircraft. Oman’s Public Authority for Civil Aviation made the sultanate’s announcement, without elaborating on its reasoning. State-owned Oman Air operates five Max 8 aircraft and said it was rescheduling other planes for its flights.

Singapore has temporarily banned Max 8 jets — and other models in the Max range — from entering and leaving the country. The Civil Aviation Authority said it was “closely monitoring the situation” and the ban will be “reviewed as relevant safety information becomes available.” SilkAir, a regional carrier owned by Singapore Airlines, has six Max 8 jets. It said the ban “will have an impact on some of the airline’s flight schedules.”

Comair, the operator of British Airways and Kulula flights in South Africa, has grounded its Max 8 while it consults with Boeing, other operators and technical experts. Its statement did not say how many planes were affected. It said the decision was made without intervention from regulatory authorities.

South Korean airline Eastar Jet has suspended operations of its two Max 8 planes and replaced them with Boeing 737-800 planes starting Wednesday on routes to Japan and Thailand. The airline said it hasn’t found any problems, but is voluntarily grounding the planes in response to customer concerns.

Turkish Airlines has suspended all Max flights. In a statement Tuesday on Twitter, CEO Bilal Eksi said the suspension would continue until the “uncertainty affecting safety is cleared.”

The UAE’s General Civil Aviation Authority has banned the aircraft from its airspace in what is said was “a precautionary measure.” The Max is the workhorse of the Dubai government-owned budget carrier FlyDubai. It operates 11 Max 8 and 2 Max 9 jets. Its total fleet is around 60 aircraft, including other models of the 737.

Vietnam has banned Max planes from flying into its airspace. The director of Vietnam’s Civil Aviation Authority said Wednesday that airlines flying those models of planes will have to change the aircraft for safety purposes. The ban lasts until further notice. None of Vietnam’s four airlines uses the Max model planes in their fleets, but Korea’s Eastar Jet, Thai Lion Air and Malaysia’s Malindor Air fly those planes to Vietnamese destinations. </s> Boeing shares fell more than 9 per cent Monday in pre-market trading

Aviation authorities in China, Indonesia and Ethiopia ordered airlines to ground their Boeing 737 Max 8 planes Monday after one crashed in Ethiopia, killing all 157 people on board.

The crash of the Ethiopian Airlines jet shortly after it took off from Addis Ababa on Sunday is drawing renewed scrutiny of the plane just four months after a similar crash of the same model that killed 189 people in Indonesia.

Chicago-based Boeing said it did not intend to issue any new guidance to its customers. It does plan to send a technical team to the crash site to help Ethiopian and U.S. investigators.

The 737 is the bestselling airliner in history, and the Max, the newest version of it with more fuel-efficient engines, is a central part of Boeing’s strategy to compete with European rival Airbus.

“Safety is our number one priority and we are taking every measure to fully understand all aspects of this accident, working closely with the investigating team and all regulatory authorities involved,” the company said in a statement.

A spokesman for Ethiopian Airlines, Asrat Begashaw, said the carrier had grounded its remaining four 737 Max 8 planes until further notice as an “extra safety precaution.”

The airline had been using five new 737 Max 8s and awaiting delivery of 25 more. Asrat said the search for body parts and debris from the crash was continuing.

China’s Civil Aviation Administration said that it ordered airlines to ground all 737 Max 8 aircraft, in line with the principle of “zero tolerance for security risks.”

It said it would issue further notices after consulting with the U.S. Federal Aviation Administration and Boeing.

Chinese carriers and leasing companies operate 96 Boeing 737 8 MAXs, according to the government, with dozens more believed to be on order. China Southern Airlines is one of Boeing’s biggest customers for the aircraft.

Indonesia also grounded 11 737 Max 8s for inspections to ensure flight safety and that the planes are airworthy, said Director General of Air Transportation Polana B. Pramesti.

Cayman Airways also said it was temporarily grounding two Boeing 737 Max 8 aircraft.

Real time flight radar apps showed dozens of the aircraft still operating around the globe.

The head of Indonesia’s national transport safety agency, Soerjanto Thahjono, offered to aid the Ethiopian investigation into Sunday’s crash.

The U.S. National Transportation Safety Board likewise said it was sending a team to help Ethiopian authorities. Boeing and the U.S. investigative agency are also involved in the probe into the Lion Air crash in Indonesia in October.

Like the Ethiopian Airlines crash, which happened minutes after the jet’s takeoff from Addis Ababa, the Lion Air jet that crashed off Indonesia had erratic speed during the few minutes it was in the air.

Safety experts cautioned, however, against drawing too many parallels between the two disasters.

“I do hope though that people will wait for the first results of the investigation instead of jumping to conclusions based on the very little facts that we know so far,” said Harro Ranter, founder of the Aviation Safety Network, which compiles information about accidents worldwide.

The situation will be better understood after investigators analyze the Ethiopian plane’s black boxes, said William Waldock, an aviation-safety professor at Embry-Riddle Aeronautical University. An airline official said Monday that the black box and cockpit voice recorder had been found, but the box was partially damaged.

Waldock said the way the planes both crashed — a fatal nosedive — was likely to raise suspicion. Boeing will likely look more closely at the flight-management system and automation on the Max, he said.

“Investigators are not big believers in coincidence,” he said.

Boeing has delivered about 350 737 Max planes to scores of airlines and has orders for more than 5,000.

Shares in the company fell more than 9 per cent Monday in pre-market trading.

Alan Diehl, a former National Transportation Safety Board investigator, said reports of large variations in vertical speed during the Ethiopian jetliner’s ascent were “clearly suggesting a potential controllability problem.”

Other possible causes include engine problems, pilot error, weight load, sabotage or bird strikes, he said.

Ethiopian has a good reputation and the company’s CEO told reporters no problems were spotted before Sunday’s fight. But investigators also will look into the plane’s maintenance, which may have been an issue in the Lion Air crash.

Days after the Indonesian accident, Boeing notified airlines that faulty information from a sensor could cause the plane to automatically point the nose down. The automated system kicks in if sensors indicate that a plane is about to lose lift, or go into an aerodynamic stall. Gaining speed by diving can prevent a stall.

The notice reminded pilots of the procedure for handling such a situation, which is to disable the system causing the automatic nose-down movements.

Indonesian investigators are examining whether faulty readings from a sensor might have triggered the automatic nose-down command to the plane, which the Lion Air pilots fought unsuccessfully to overcome.

The Lion Air plane’s flight data recorder showed problems with an airspeed indicator on at least four previous flights, although the airline initially said the problem was fixed.

Boeing Chairman and CEO Dennis Muilenburg said in December that the Max is a safe plane.

Mideast budget airline FlyDubai says it will continue to fly Boeing 737 Max 8 and 9 aircraft after reviewing a recent U.S. regulator statement about the aircraft.

Several airlines around the world have grounded the planes after a fatal crash in Ethiopia on Sunday and one in Indonesia last year.

The U.S. Federal Aviation Administration said Monday that while others have drawn similarities between the Indonesia and Ethiopia crashes, the agency was not. The FAA also said that no later than April it expects Boeing will complete changes, including new training for pilots in automated anti-stall technology that is suspected of playing a role in the Indonesia crash.

FlyDubai said Tuesday that "no further action is required at this time" over the aircraft, which is a workhorse in the Dubai government-owned carrier's fleet.

FlyDubai' statement Tuesday comes after it said Monday that it remains "confident in the airworthiness of our fleet."

India's Jet Airways says it has grounded its five Boeing 737 Max 8 aircraft after a crash in Ethiopia that killed all 157 people on board.

The airline said it is not flying any of the 737 Max planes in its fleet and is "in contact with the manufacturer."

On Monday, India's aviation watchdog said it ordered a safety assessment of the aircraft. It also issued safety instructions for flying Boeing 737 Max 8 aircraft.

The directions call for the pilot-in-command to have at least 1,000 hours of flying experience and the co-pilot to have 500 hours on Boeing 737 NG type aircraft.

Indian airline SpiceJet also has Boeing 737 Max 8 aircraft, but it's unclear if those planes are grounded. Calls and emails to the company were unanswered Tuesday.

South Korean transportation authorities are conducting a safety inspection of a local airline that uses the same aircraft involved in the Ethiopian Airlines plane crash that killed 157 people.

An official from low-cost carrier Eastar Jet said Tuesday it doesn't have immediate plans to suspend operations of its two Boeing 737 Max 8 planes it uses on routes to Japan and Thailand. He said it will wait for the inspection's outcome.

No other South Korean carriers operate the plane. South Korea's Transportation Ministry says the inspection on Eastar began hours after the Ethiopian Airlines crash.

The Eastar official says government officials are reviewing Eastar's flight operation manuals and the planes' machinery and software. She said the airline was getting calls from worried customers, but no cancellations.

Singapore's civil aviation authority says it has temporarily banned all Boeing 737 Max planes from entering and leaving the country.

It noted in a statement on Tuesday that there have been two fatal accidents involving the aircraft in less than five months. Sunday's deadly crash of an Ethiopian Airlines 737 Max 8 killed all 157 people on board.

The authority said the suspension starting later Tuesday will be "reviewed as relevant safety information becomes available."

The suspension will affect SilkAir, a regional carrier that's wholly owned by Singapore Airlines. It has six Boeing 737 Max 8 planes.

The authority said that flights to Singapore by China Southern Airlines, Garuda Indonesia, Shandong Airlines and Thai Lion Air will also be affected.

Fiji Airways says it will continue flying its two Boeing 737 Max 8 planes to Pacific destinations.

Some airlines have grounded their Max 8 planes after an Ethiopian Airlines jetliner crashed on Sunday, killing 157 people. Another Max 8 plane crashed in Indonesia last year.

Fiji's national carrier said in a statement Tuesday it's following the situation closely and has full confidence in the airworthiness of its fleet. The airline says it mainly uses the MAX 8 planes on routes connecting Fiji, Australia and New Zealand.

New Zealand's Civil Aviation Authority said Fiji Airways was the only carrier landing MAX 8 planes in New Zealand and it could continue doing so.

In the United States, Transportation Secretary Elaine Chao said her department was monitoring developments. The FAA noted the investigation into the crash had just begun and it has not yet drawn similarities between the Indonesia and Ethiopia crashes.

India's aviation watchdog issued safety instructions after the Ethiopia crash, calling for the pilot-in-command to have at least 1,000 hours of flying experience and the co-pilot to have 500 hours on Boeing 737 NG type aircraft.

Brazil's Gol Airlines is suspending the use of its 121 Boeing 737 Max 8 aircraft following the deadly Ethiopian Airlines crash involving the same airplane.

The company said in a press release Monday night that as of 8 p.m. local time it would be temporarily stopping the commercial use of the airplanes.

The statement says Gol is fully confident in Boeing's safety operations and it is following updates about the investigation into the 737 Max 8 in order to return the aircraft to use as soon as possible.

Gol says that since it started using the Boeing 737 Max 8 last June, the aircraft have made nearly 3,000 flights with "total security and efficiency."

The Mexican airline Aeromexico says it is suspending flights with its six Boeing 737 Max 8 jetliners following the crash of a Max 8 aircraft in Ethiopia that killed 157 people.

The company says it trusts "fully" in the safety of its fleet but adds that the grounding has been ordered to ensure "the safety of its operations and the peace of mind of its customers."

A statement issued Monday evening says the airline is in communication with Boeing as well as aviation authorities about the plane model. It says other planes will take over the flights usually flown by its Max 8 jets.

Airlines in Ethiopia, China and Indonesia have temporarily grounded their Max 8s, in addition to Caribbean carrier Cayman Airways, Comair in South Africa and Royal Air Maroc in Morocco

The Federal Aviation Administration says it expects Boeing will soon complete improvements to an automated anti-stall system that is suspected of contributing to a deadly crash of a Boeing 737 Max 8 in October.

The FAA said Monday that Boeing will also update training requirements and flight crew manuals related to the system.

The system automatically points the plane's nose down if sensors indicate the plane could be in danger of losing lift, or stalling. Sensors on the plane operated by Indonesia's Lion Air gave out faulty readings on its last four flights.

On the fatal October flight, pilots apparently struggled in vain to fight against the automated nose-down commands.

The FAA tried to discourage comparisons between the Lion Air crash and Sunday's deadly crash of an Ethiopian Airlines 737 Max 8. Both performed erratically shortly after takeoff, then went into nosedives. Weather did not appear to be a factor in either one.

"External reports are drawing similarities between (the Ethiopian) accident and the Lion Air Flight 610 accident," the FAA said. "However, this investigation has just begun and to date we have not been provided data to draw any conclusions or take any actions."

State-run carrier Oman Air says it is in close contact with Boeing after the crash of an Ethiopian jetliner, the same model that it uses widely.

Oman Air tweeted Monday that is talking to Boeing "to understand if there are any implications" for other airlines operating Boeing 737 MAX 8 aircraft.

It added: "Oman Air's primary and overriding consideration is the safety and well-being of its staff and guests."

Oman Air operates five Boeing 737 MAX 8 aircraft. Oman is a sultanate on the eastern edge of the Arabian Peninsula.

The crash of the Ethiopian Airlines 737 MAX 8 on Sunday killed 157 people. A similar Lion Air plane crashed in Indonesia in October, killing 189 people.

Chinese and Indonesian regulators ordered their airlines to temporarily ground their Boeing 737 MAX 8 planes.

Indonesia has grounded Boeing 737 MAX 8 planes for inspections following the Ethiopian Airlines crash, the second for the new aircraft since October.

Director General of Air Transportation Polana B. Pramesti said the grounding was taken to ensure flight safety in Indonesia. He said the inspections will ensure the planes are airworthy.

The crash of an Ethiopian Airlines 737 MAX 8 killed 157 people Sunday. A Lion Air model of the same plane crashed in Indonesia in October, killing 189 people.

There are currently 11 MAX 8 planes operated by airlines in Indonesia including 10 by Lion Air and 1 by national carrier Garuda.

Boeing says it is not issuing new guidance to airlines about its 737 Max 8 aircraft after a second fatal crash on Sunday.

A statement Monday referred questions about the grounding of planes to airlines and aviation authorities. It said "at this point, based on the information available, we do not have any basis to issue new guidance to operators."

China has ordered its airlines to ground their Boeing 737 Max 8 aircraft by 6 p.m., and Ethiopian Airlines and Cayman Airways both are doing the same.

A crash of an Ethiopian Airlines 737 Max 8 killed 157 people Sunday. A Lion Air model of the same plane crashed in Indonesia in October, killing 189 people.

A spokesman says Ethiopian Airlines has grounded all its Boeing 737 Max 8 aircraft as a safety precaution.

Asrat Begashaw said Monday that although it is not yet known what caused the crash on Sunday, the airline decided to ground its remaining four 737 Max 8 planes until further notice as "an extra safety precaution." Ethiopian Airlines was using five new 737 Max 8 planes and was awaiting delivery of 25 more.

Begashaw said searching and digging to uncover body parts and aircraft debris will continue. He said forensic experts from Israel have arrived in Ethiopia to help with the investigation.

The Middle Eastern budget carrier FlyDubai says it is in touch with Boeing and "monitoring the situation" regarding its 737 Max 8 aircraft, but has faith in its planes' airworthiness following an Ethiopian Airlines crash involving the model.

FlyDubai operates 11 Boeing 737 MAX-8 and two Boeing MAX-9 jetliners. The Dubai government-owned airline said in emailed statements Monday that it "went through a rigorous process" to choose the right aircraft for its operations and noted that it adheres to all regulations regarding its planes.

It says it remains "confident in the airworthiness of our fleet."

The Ethiopian crash killed 157 people aboard on Sunday. Chinese regulators ordered all Chinese airlines to temporarily ground their Boeing 737 Max 8 planes on Monday.

Cayman Airways says it is temporarily grounding the two Boeing 737 Max 8 aircraft it operates in the wake of an Ethiopian Airlines crash involving the same plane model.

The Caribbean carrier said the grounding would take effect Monday. While he acknowledged the cause of the Ethiopian crash was unclear, airline President and CEO Fabian Whorms said the airline was taking the step because of its "commitment to putting the safety of our passengers and crew first."

He said the move would lead to scheduling changes as the carrier copes with aircraft shortages.

Cayman received its first Max 8 in November and its second just this month.

The airline is the flag carrier of the Cayman Islands, a British Overseas Territory.

The head of Indonesia's national transport safety agency says it will offer to assist the Ethiopian investigation into the crash of a Boeing 737 MAX 8 plane.

The same model of plane, operated by Lion Air, crashed in Indonesia in October, killing all 189 people on board. Like the Ethiopian Airlines crash on Sunday, which killed 157 people, the Lion Air jet had erratic speed in the few minutes it was in the air.

Soerjanto Tjahjono, chairman of the National Safety Transportation Board, said Monday that Indonesia can be a party to Ethiopia's investigation because one of its citizens was among those who died in the crash.

He said, "However, we will also offer to assist the investigation process." </s> China on Monday ordered domestic airlines to suspend commercial operation of the Boeing 737 MAX 8, citing the Ethiopian Airlines crash and another deadly accident of that same model in Indonesia.

Noting the “similarities” between the two accidents, China’s Civil Aviation Administration said domestic airlines had until 6:00 pm local time (1000 GMT) to ground all 737 MAX 8 aircraft.

Operation of the model will only resume after “confirming the relevant measures to effectively ensure flight safety”, the administration said in a statement.

The aviation authority will contact the US Federal Aviation Administration and Boeing, it said.

The statement cited the Kenya-bound Ethiopian Airlines flight that crashed minutes after takeoff from Addis Ababa on Sunday, killing all 157 people on board, including eight from China.

It also mentioned the Indonesia Lion Air flight, which crashed after takeoff from Jakarta in October, killing all 189 people on board.

China is an important market for the US aircraft company, accounting for about one-fifth of worldwide deliveries of Boeing 737 MAX models.

The company has delivered 76 Boeing 737 MAX aircraft to Chinese airlines, which have ordered another 104, according to data from the aircraft maker’s website updated through January.

Boeing and joint venture partner Commercial Aircraft Corporation of China (COMAC) operate a plant in the eastern city of Zhoushan that completes the interiors of 737 MAX planes for Chinese airlines.

The factory delivered its first MAX 8 plane to Air China in December. The planes are assembled in Renton, Washington state, and taken to Zhoushan to finish the interior work, according to Boeing. </s> Airline regulators across the globe are grounding Boeing 737 Max 8 planes, joining an ever expanding list of countries banning the plane from their airspace. This comes in the wake of Sunday's deadly plane crash in Ethiopia that killed all 157 people on board. The cause of the crash is still under investigation.

The latest move came Tuesday from the European Union Aviation Safety Agency (EASA) when it announced a suspension of two Boeing 737 Max models in all flights in the European bloc.

The wave of bans follows the Civil Aviation Administration of China's decision on Monday to order the country's airlines to suspend all commercial operations of their Boeing 737 Max 8 jets.

The U.S. Federal Aviation Administration does not plan to ground the jets in the United States but is facing growing pressure to do so.

The FAA announced Monday that it would require a series of design changes for the Boeing 737 Max fleet.

In the U.S., Southwest Airlines uses a fleet of 34 Boeing 737 Max 8 aircraft and is not planning any change in service. Likewise, American Airlines, which operates 24 of the planes, is not planning to ground them.

The full list of countries and airlines that have announced a ban is below: </s> Boeing Chief Executive Officer Dennis Muilenburg faces his biggest crisis yet following the second deadly crash of a 737 Max jetliner, as some airlines grounded the best-selling plane and the shares logged their biggest loss since the 9/11 attacks.

China ordered its carriers to ground all 96 of Boeing’s newest 737 model, while Indonesia said it would also halt flights after Ethiopian Airlines Flight 302 went down in a field shortly after takeoff Sunday, killing all 157 people on board. While the flight recorders have now been recovered and must be analyzed, the disaster bore similarities to the doomed Lion Air 737 Max that crashed in October.

The 737 Max is Boeing’s most important aircraft type, generating almost one-third of the company’s operating profit and forming the backbone of many global airline fleets who use the model and Airbus’s competing A320 family on shorter routes.

Boeing sank 11 percent to $374.31 at 9:37 a.m. in New York after sliding as much as 13 percent for the biggest intraday decline since Sept. 17, 2001, the first day of trading after the 9/11 attacks.

“Boeing has lost control of the timetable to provide the safe, reliable solution,” said Neil Hansford, chairman of the Australian consultancy firm Strategic Aviation Solutions. “The longer it goes, the more chance Boeing has of losing orders.”

The grounding in China, followed by the Indonesian air safety regulator’s order to halt 737 Max flights from Tuesday, raises the specter of other countries following suit. South Korea began a special inspection of the aircraft, while in Europe, regulators said they’re in contact with their U.S. counterparts as well as Boeing, but that it’s too soon to take action.

While the groundings in China and elsewhere are important, most nations typically wait to act until the U.S. and Europe issue findings on aviation matters. The Federal Aviation Administration and the European Union Aviation Safety Agency oversee the world’s largest aircraft manufacturers and take the lead in ensuring the safety of their planes.

U.S. carriers such as Southwest Airlines Co., American Airlines Group Inc. and United Continental Holdings Inc. are still flying the 737 Max.

Investigators have recovered the cockpit voice and flight-data recorders, Ethiopian Airlines said Monday, a significant step forward in piecing together what happened.

Chinese airlines accounted for about 20 percent of 737 Max deliveries worldwide through January, and further purchases of the Chicago-based planemaker’s aircraft are said to have been touted as a possible component of a trade deal with the U.S.

China Southern Airlines Co. has 16 of the aircraft, with another 34 on order, according to data through January on Boeing’s website. China Eastern Airlines Corp. has 13, while Air China Ltd. has 14, Boeing says. Other Chinese airlines that have bought the Max include Hainan Airlines Holdings Co. and Shandong Airlines Co., the data show.

Lion Air, which is based in Indonesia, is one of the biggest customers, having ordered 201 Max planes and taken delivery of 14.

The single-aisle 737 Max is poised to generate about $30 billion in annual revenue as factory output rises to a 57-jet monthly pace this year, according to Bloomberg Intelligence estimates.

The disaster in Ethiopia followed the crash of Lion Air’s 737 Max off the coast of Indonesia on Oct. 29. A preliminary report into that flight indicated that pilots struggled to maintain control following an equipment malfunction. The U.S. Federal Aviation Administration is working with Boeing on a possible software change to reduce the chances that such a failure could cause an accident in the future.

Boeing responded to the earlier crash by advising pilots that the Max’s so-called angle-of-attack sensor can provide false readings, causing the plane’s computers to erroneously detect a mid-flight stall in airflow. That in turn can cause the aircraft to abruptly dive to regain the speed the computer has calculated it needs to keep flying. Pilots could counteract the sudden downward tilt by following a checklist in their training manual, the planemaker said.

The doomed Ethiopian jetliner left Addis Ababa at 8:38 a.m. local time, and contact was lost six minutes later, the company said in a statement. There were people from 35 nations on board, including 32 Kenyans, 18 Canadians, nine Ethiopians and eight Americans. The United Nations, which is hosting an environmental conference this week in Nairobi, said it lost 19 staff members in the crash.

The pilot of the ET302 reported problems shortly after takeoff and was cleared to return to the airport, said the airline’s chief executive officer, Tewolde GebreMariam. The 737 Max 8 hadn’t had any apparent mechanical issues on an earlier flight from Johannesburg, he said.

Ethiopian Airlines had five of the planes in operation as of the end of January and orders for a further 25, according to Boeing’s website. Boeing has dispatched a technical team to assist the investigation into the Ethiopian Airlines plane, which was delivered new in November to Africa’s biggest carrier, while the FAA, which originally certified the 737 Max and U.S. National Transportation Safety Board have also joined the probe.

Jet Airways India Ltd. and SpiceJet Ltd., two Indian airlines that use the 737 Max jet, and the country’s regulators have asked Boeing for information following the Ethiopia crash.

Southwest Airlines says it’s “confident in the safety of our fleet” including its 34 737 Max 8 planes American Airlines Will closely monitor the investigation via Boeing and NTSB Singapore Airlines Monitoring the situation; the 737 Max 8 flights operated by SilkAir are flying as scheduled Icelandair Says it’s had no issues with its three 737 Max 8s Korean Air Due to receive its first Max in April, is monitoring the situation Cayman Airways Grounds both its Boeing 737 Max 8 aircraft Thailand Says it currently has no plans to ground Boeing 737 Max jets China Grounds entire fleet of Boeing 737 Max 8 jets. China Eastern to talk with Boeing about losses caused by grounding. Flydubai Says it’s monitoring situation and in touch with BoeingA U.S.-ordered grounding of an entire model of aircraft is extremely rare and in the past has typically not occurred so soon during an investigation when few details are known. The last time the agency did so was in January 2013 as a result of overheating lithium-ion batteries on Boeing’s 787 model. The agency only acted after the second such incident occurred.

Muilenburg, 55, was running Boeing’s defense business during the Dreamliner’s grounding. Since he took the reins as CEO in July 2015, Boeing has dramatically expanded cash flow and the shares have tripled. That has boosted the company’s market value by $140 billion and made Boeing the biggest U.S. industrial company. </s> After the second deadly crash involving the model in five months, several airlines have grounded the model

Canadian Transport Minister Marc Garneau says “all options are on the table” with regard to the country’s fleet of Boeing 737 Max 8 aircraft but says the government currently has no plans to order the grounding of the plane.

Garneau’s comments came minutes after announcements from Britain, Germany, France and Ireland that they were grounding or closing airspace to the new Boeing plane involved in the Ethiopian Airlines disaster.

He later tweeted that he has cancelled all his meetings and public events on Tuesday to meet with his Civil Aviation Expert Panel and will consider all potential actions.

Canada is working with the U.S. Federal Aviation Authority to determine if action is required.

No U.S. airlines have grounded the Boeing 737 Max 8 models that they fly, but at least one group representing flight attendants at a major carrier says it does not want to put its members on the plane until further investigations are completed.

After the second deadly crash involving the model in five months, several airlines and countries in Asia, Europe and the Middle East have grounded it or banned it from their airspace.

The Association of Professional Flight Attendants, which represents more than 26,000 flight attendants at American Airlines, called on CEO Doug Parker to “strongly consider grounding these planes until an investigation can be performed.” The group said flight attendants will not be forced to fly if they feel unsafe.

Brian Parrish, a spokesman for Southwest Airlines which flies 34 Max 8s, said the carrier remains confident about the plane’s safety. American Airlines Group, which flies 24 of the planes, said it has full confidence in the model.

China's civilian aviation authority has ordered all Chinese airlines to temporarily ground their Boeing 737 Max 8 planes after one of the aircraft crashed in Ethiopia.

The Civil Aviation Administration of China said the order was issued at 9 a.m. Beijing time Monday and would last nine hours.

It said the order was taken out of safety concerns because the crash was the second after another of the planes fell into the ocean off the coast of Indonesia in similar circumstances on Dec. 29, killing all aboard.

It said further notice would be issued after consultation with the U.S. Federal Aviation Administration and Boeing on safety measures taken.

Eight Chinese nationals were among the 157 people aboard the plane when it crashed Sunday shortly after takeoff.

Boeing's newest version of its most popular plane is again in the spotlight after a deadly accident in Ethiopia.

A Boeing 737 Max 8 operated by Ethiopian Airlines crashed shortly after taking off Sunday from Addis Ababa, killing all 157 people on board.

The plane was new. The weather was clear. Yet something was wrong, and the pilots tried to return to the airport. They never made it.

Those circumstances make the accident eerily similar to an October crash in Indonesia that killed all 189 people on the plane.

Safety experts are noticing the similarities but say a verdict on the plane should wait until investigations are complete.

Boeing says its plane is safe. The company's sales didn't suffer after the Indonesia crash, and its stock price has soared.
The European Union, Australia, India, Malaysia, Singapore, and Turkey ground all Boeing 737 MAX 8 jets. This means 40% of the global fleet is now grounded, with Indonesia, China and several airlines grounding their aircraft yesterday. Boeing states they will issue a software update for the model within weeks.
