The airline in a statement on Thursday said it does not fly the Boeing 737 MAX-8 aircraft and "will not, and in fact can not, introduce any aircraft into its fleet that does not meet the most stringent global and domestic regulations".
In a statement signed by the Director General of the agency, Silas Udahemuka, the authority said that the ban takes effect immediately and remain in effect till further notice.
All Boeing Max jets have been grounded worldwide due to similarities between both crashes.
Most of the countries have grounded the planes, including the US, China, India, Brazil and many countries of the European Union.
The US Federal Aviation Administration said on Wednesday it prohibited all flights of Boeing 737 MAX in the US airspace following the recent crash of this type of aircraft.
On Thursday morning in Addis Ababa, grieving relatives of the 157 victims of Sunday's air disaster boarded buses for a three-hour journey to the crash site in a field 37 miles outside the Ethiopian capital, Reuters reports.
The causes of both crashes are still under investigation.
Judge to be assigned to Jussie Smollett case during court hearing today
Jussie Smollett pleaded not guilty to 16 felony counts Thursday morning in Cook County, Illinois, the Associated Press reported. The star's absence comes after he was arrested last month for staging an attack against himself, according to Chicago Police.
Legislators noted that there have been no confirmed incidents in 50,000 North America flights with the 737 MAX 8 and questioned if training by carriers overseas was an issue.
The Boeing 737 was previously the best-selling jet in history, and the new Max 8 was meant to be a good option for mid-range flights. McCallum said if a safety mechanism is suspect in either case, training to disable it is not a long-term fix.
Within a minute of the flight's departure, Captain Yared Getachew reported a "flight control" problem as the aircraft was well below the minimum safe height from the ground during a climb, the Times reported, citing the person.
Attention has focussed since the Lion Air crash on an automated anti-stall system in the 737 Max that dips the plane's nose down.
Japan Airlines Co. has no plans to acquire the 737 Max 8. The black box of the plane were brought on Thursday to the analysis to France.
"We believe the company has avenues to work around the grounding, including the longer in-service use of older aircraft, possible access to third-party aircraft, the temporary use of different gauge aircraft and if necessary the temporary suspension of some routes", he wrote in a research note.
He also noted that investigators have not yet found a clear link between the system that malfunctioned prior to the Lion Air crash and the Ethiopia accident.
