A preliminary study of the flight data recorders show "clear similarities between Ethiopian Airlines flight 302 and Indonesian Lion Air Flight 610", Dagmawit Moges said Sunday at a press conference in Addis Ababa.
Since the Ethiopian crash, which claimed 157 lives, questions have been raised not only about Boeing, but also the FAA and its close relationship with the company.
Boeing's shares fell by over 11% last week and the company lost £26 billion of its market value, the biggest hit the company had taken in two decades.
"The data was successfully recovered". Both the American team and our (Ethiopian) team validated it.
In Washington, however, US officials told Reuters the FAA and US National Transportation Safety Board (NTSB) had not yet validated the data.
Under scrutiny is a new automated system in the 737 MAX model that guides the nose lower to avoid stalling.
The paper also said U.S. FAA followed a standard certification process on the MAX rather than extra inquiries.
The Wall Street Journal reported that prosecutors and the U.S. Department of Transportation were scrutinizing the FAA's approval of the MAX series, while a jury had issued a subpoena to at least one person involved in its development.

Investigators are reportedly seeking documents and correspondence related to the Boeing 737 MAX's development.
According to BBC News, in both Lion Air and Ethiopian Airlines' plane crashes, flight tracking data revealed that the aircrafts' altitude had changed sharply.
A Boeing spokesman declined commenting to TheWSJ on "legal matters or governmental inquiries".
Earlier Sunday, the Journal also reported the inspector general's investigation, citing a government official briefed on its status.
It is unknown if the Ethiopian Airlines flight that crashed a week ago will play any role in this investigation or not.
- The agency said that information had been transferred to Ethiopian investigators and that its technical work on the flight data recorder and cockpit voice recorder had been done.
Previous air crash reports show that in such high-profile cases there can be disagreements among parties about the cause. The caskets were empty because authorities have said that recovering and identifying the remains will take months.
This is done through horizontal stabilizers on the plane's tail which are activated by the aircraft's flight control computer.
In a statement Wednesday, the FAA said, "The FAA is ordering the temporary grounding of Boeing 737 MAX aircraft operated by USA airlines or in US territory". The FAA did not immediately respond to a request for comment on Canada's action.More news: Google Pixel 3 owners get huge Android boost as major upgrade revealed
