Civil aviation authorities and airlines across the globe have begun to curtail B737 MAX operations following the crash of an Ethiopian Airlines B737 MAX 8, ET-AVJ (msn 62450), on Sunday, March 10. The four-month old jet was climbing out of Addis Ababa en route for Nairobi Jomo Kenyatta when it lost height and impacted the ground killing all 149 passengers and 9 crew onboard. The disaster comes barely four months after the crash of a Lion Air B737 MAX 8 in Indonesia which killed all 189 onboard.

As of Monday, March 11, Ethiopian Airlines has said that while the cause of the crash is still unknown, it has grounded its fleet of four remaining B737 MAX 8s "as an extra safety precaution".

For its part, the Civil Aviation Administration of China (CAAC) has ordered all local operators to ground their B737 MAX 8s.

"In line with the management principle of zero tolerance for safety hazards and strict control of safety risks, in order to ensure the safety of civil aviation in China, at 0900L on March 11, the Civil Aviation Administration issued a notice requesting domestic airlines to suspend the commercial operation of the Boeing 737 MAX 8 aircraft as from 1800L on March 11, 2019," it said in a statement.

China Southern Airlines operates twenty-three, Air China sixteen, Hainan Airlines eleven, Xiamen Airlines ten, Shanghai Airlines nine, Shandong Airlines six, 9 Air one, Fuzhou Airlines two, Kunming Airlines two, Lucky Air (China) three, and Okay Airways two.

Cayman Airways has also announced it has grounded its pair of B737 MAX 8s, one of which was only delivered last week.

Garuda Indonesia operates one B737 MAX 8 and Lion Air ten.

"Until now, we have continued to take corrective steps starting from operational procedures and additional training and following up on the Airworthiness Directive issued by the Federal Aviation Administration," Director General of the DJPU's Air Transportation division, Polana B Pramesti, said in a statement. He added that his organization would closely liaise with the entities involved in the Ethiopian crash investigation.

"We will also communicate and monitor the investigation process of the B737 MAX 8 type that crashed in Ethiopia and coordinate with the FAA to decide on further steps in the improvement of the B737 MAX's operations," he added.

In Fiji, Fiji Airways said it has full confidence in the airworthiness of its pair of B737 MAX 8s and will continue to operate them for the time being.

The Zimbabwean Government has now deemed the B737 MAX 8 "an unsafe aircraft", the Deputy Minister of Information, Energy Mutodi, has said.

"While investigations around the plane crash involving Indonesian & Ethiopian planes are continuing, we would like to advise Zimbabwean citizens that we have classified the American-built Boeing 737 MAX 8 as an unsafe aircraft due to its mulfunctioning[sic] auto-pilot software," he said via Twitter.

"A combination of malfunctioning sensors, an unfamiliar auto-diving software and inability to resist aerodynamic roughness in the lower atmosphere make the American Boeing 737 MAX 8 prone to take-off and landing accidents."

The Civil Aviation Authority of Zimbabwe (CAAZ) has yet to comment on whether it will ban B737 MAX 8 flights to/from the country, based on Mutodi's comments.
