SHANGHAI: China's aviation regulator on Monday (Mar 11) grounded nearly 100 Boeing 737 MAX 8 aircraft operated by its airlines, more than a quarter of the global fleet of the jets, after a deadly crash of one of the planes in Ethiopia.
An Ethiopian Airlines 737 MAX 8 bound for Nairobi crashed minutes after take-off on Sunday, killing all 157 people on board and prompting the carrier to ground the rest of its fleet of the jets.
Chinese state TV said eight Chinese passengers were aboard Ethiopian Airlines flight ET302, which was carrying 149 passengers and eight crew members.
It was the second crash of the 737 MAX 8, the latest version of Boeing's workhorse narrowbody jet that first entered service in 2017.

In October, a 737 MAX 8 flown by Indonesian budget carrier Lion Air flying from Jakarta on a domestic flight crashed 13 minutes after take-off, killing all 189 passengers and crew on board.
The Civil Aviation Administration of China (CAAC) said all Chinese airlines had to suspend their use of the 737 MAX 8 by 6pm. It said it would notify airlines as to when they could resume flying the jets after contacting Boeing and the US Federal Aviation Administration (FAA) to ensure flight safety.
"Given that two accidents both involved newly delivered Boeing 737-8 planes and happened during take-off phase, they have some degree of similarity," the CAAC said, adding that the order was in line with its principle of zero-tolerance on safety hazards. The 737 MAX 8 is sometimes referred to as the 737-8.
A Boeing spokesman declined to comment.
Chinese airlines have 96 737 MAX 8 jets in service, the state company regulator said on Weibo, including Air China, China Eastern Airlines, China Southern Airlines and Hainan Airlines.
Chinese aviation data firm Variflight said at least 29 international and domestic flights on Monday had been cancelled and that airlines had swapped out the plane on 256 other flights that had been scheduled to use it.
China Eastern's chairman, Liu Shaoyong, told financial publication Caixin on the sidelines of a parliament meeting in Beijing that it would only consider resuming 737 MAX 8 flights once Boeing issued a safety commitment for the jets and proved that there was no aircraft design link between the two crashes.
The cause of the Indonesian crash is still being investigated. A preliminary report issued in November, before the cockpit voice recorder was recovered, focused on airline maintenance and training and the response of a Boeing anti-stall system to a recently replaced sensor but did not give a reason for the crash.

Ethiopian Airlines said it had grounded its 737 MAX 8 fleet until further notice as an "extra safety precaution" even though it did not know the cause of Sunday's crash.
The airline has a remaining fleet of four of the aircraft, according to flight tracking website FlightRadar24.
Cayman Airways said it had grounded both of its new 737 MAX 8 jets until it got more information.
But no other airlines or regulators said they were grounding the aircraft. By the end of January, Boeing had delivered 350 of the 737 MAX family jets to customers, with another 4,661 on order.
A US official told Reuters the United States was unsure of what information China was acting on.
Speaking on condition of anonymity due to the sensitivity of the matter, the officials said there were no plans to follow, given the 737 MAX 8 had a stellar safety record in the United States and there was a lack of information about the cause of the Ethiopian crash.
Western industry sources say China has been at pains in recent years to assert its independence as a safety regulator as it negotiates mutual safety standard recognition with regulators in the United States and Europe.
In 2017, it signed a mutual recognition deal with the FAA, but industry sources say it has struggled to gain approval from the FAA that would allow it to sell its self-developed C919 airliner to Western airlines.
Chinese aviation expert Li Xiaojin said the grounding was "reasonable and justified" but that some disruptions to passengers' travel plans could be expected.
But he said he did not anticipate a major problem since Chinese airlines operated fewer than 100 of the aircraft, compared with a combined fleet of more than 2,000 planes.
Indonesia said it would monitor its airlines operating the 737 MAX 8, which include Lion Air and Garuda Indonesia but did not mention any plan to ground them.
Garuda chief executive Ari Ashkhara said the national carrier was operating its one 737 MAX 8 with extra inspection procedures on the airspeed and altitude, flight control and stall management systems. Lion Air declined to comment.
US operators Southwest Airlines and American Airlines said they remained fully confident in the aircraft and were closely monitoring the investigation.
Singapore Airlines, whose regional arm SilkAir operates the 737 MAX 8, said it was monitoring the situation closely, without providing further details.
Malaysia Airlines, which has ordered 50 of the 737 MAX 8 jets with 25 to be delivered next year, is “studying the various options”, said Transport Minister Anthony Loke on Monday.
“There is no immediate decision … I am not saying we are continuing with it or we are cancelling it,” said Mr Loke. The airline is currently not operating any 737 MAX 8 aircraft in its fleet.
South Korea is conducting an emergency inspection on Eastar Jet's two 737 MAX 8 jets, a transport ministry official said. The airline could not be reached immediately for comment.
Korean Air Lines said there were no changes to its plans to order 30 737 MAX 8 jets, with the first expected to arrive in April.
According to Yonhap, Jeju Air, South Korea's biggest budget carrier by sales, inked a US$4.4 billion deal in November 2018 for 40 of Boeing's new B737 MAX passenger jets, with delivery set to begin in 2022.
Fiji Airways and flydubai said they were confident in the airworthiness of their 737 MAX 8 fleets.
Virgin Australia said it was too early to comment on the Ethiopian accident or its effect on the 30 737 MAX 8 jets it has on order, while Air Niugini, which has ordered four, said it had "full confidence" in the Boeing product.
