The pilots of a doomed Ethiopian Airlines jet followed all of Boeing's recommended procedures when the plane started to nose dive but still couldn't save it, according to findings from a preliminary report released Thursday by the Ethiopian government.
Initial reports from a press conference by Ethiopian officials also say the crew performed all of the procedures provided by manufacturer Boeing but was unable to control the aircraft.
"Most of the wreckage was found buried in the ground", said the report by Ethiopia's Aircraft Accident Investigation Bureau.
They suggested that Boeing review the controllability of the 737 MAX systems and that aviation authorities confirm any changes before allowing that model of plane back into the air.
News of the report's impending release came as the Federal Aviation Administration announced a new review of the 737 MAX and as the head of Boeing joined a test flight created to demonstrate the effectiveness of the company's proposed fix.
Meanwhile, Ethiopian investigators have reportedly concluded the pilots of the Ethiopian jet followed Boeing's emergency steps to disable the MACS, but to no avail. The plane crashed just six minutes after taking off from Addis Ababa, killing all 157 people on board.
Citizens from over 30 countries were on board.
More than 300 Boeing 737 Max jets have been grounded worldwide after two crashes - in Indonesia last October and in Ethiopia last month - killed almost 350 people. The software update, Boeing said in the statement, adds layers of protection and will stop erroneous data from activating the system. But Ethiopian officials said they had no indication from the flight data recorder of damage on takeoff. A final report is due within a year.More news: Alexandria Ocasio-Cortez: Campaign Finance Complaint Is 'Bogus'

Pilots of an Ethiopian Airlines jet wrestled with controls to stay aloft but plunged to the ground after restoring current to a computer system that was ordering the nose down because of faulty sensor data, a preliminary report showed on Thursday. Incorrectly sensing a stall, the aircraft's system tried to force the nose down four separate times during the flight, in the end overpowering the flight crew's ability to keep the airplane climbing.
The press conference in Ethiopia.
The Ethiopian officials did not say whether the MCAS system activated because of a faulty sensor that measures the plane's angle relative to the wind. The later they shut it off, the less time they had to recover, he said. "It is so sad to learn that our loved ones would have been spared if this problem was detected on time". The complaint, which also names Ethiopian Airlines and parts maker Rosemount Aerospace as defendants, alleged negligence and civil conspiracy among other charges.

Nader called on consumers to boycott the MAX 8 and blasted the FAA for delegating so much responsibility in certifying the plane was safe to Boeing. Criminal investigatorsin the Justice Department have sought information from Boeing on safety and certification procedures, including training manuals for pilots, along with how the company marketed the new aircraft.
Senator Roger Wicker, a Republican, said in a letter to the Federal Aviation Administration that the FAA may have been notified about the training and certification concerns as early as August 2018 - before the Indonesia crash - citing information from the whistleblowers and documents.
The review comes two days after the FAA and Boeing signalled that the planes may be grounded for longer than previously thought.
The subpoenas stem from a criminal investigation that began after the Lion Air crash, sources said.
