Ethiopian authorities recommended that Boeing reviews the plane's automated anti-stall software, called the Maneuvering Characteristics Augmentation System (MCAS), and that aviation regulators ensure the issue is dealt with before authorizing future flights.
Boeing has said it will study the report and declined to comment before doing so.
The U.S. Federal Aviation Administration said it is launching a new review of the 737 MAX.
The report, based on flight data and cockpit voice recorders on the Boeing 737 Max 8, was not released in full.
"The pilot not flying should be cranking that wheel", Goglia said.
Boeing said it would study the report.
The pilots then reversed the power switches that they had turned off - a step not included in Boeing-approved recovery procedures - which reactivated MCAS and pushed the plane's nose down, the official told the AP.
Air Line Pilots Association spokesman James Belton says Boeing, the Department of Transportation and the FAA are going to work together to come up with a fix for Boeing's 737 Max jets.
- The U.S. Federal Aviation Administration said on April 3 it was launching a new review of the 737 MAX.
The FAA's review of the MAX will be headed by former National Transportation Safety Board chairman Christopher Hart and include experts from the FAA, NASA and global aviation authorities, including Canada. Thursday's revelations raise questions about repeated assertions by Boeing and USA regulators that pilots could regain control in some emergencies by following steps that include turning off an anti-stall system designed specifically for the Max, known by its acronym, MCAS.
The preliminary report did not attribute blame for the crash and did not give detailed analysis of the flight.
Officials denied reports of tensions between Ethiopian officials and USA and other foreign investigators accredited to the probe.
Now, the first official report into the Ethiopian Airlines disaster has revealed that pilots "repeatedly" followed procedures recommended by Boeing before the crash. "As the investigation continues with more detailedanalysis, as usual we will continue with our full cooperation with the investigation team", Ethiopian Airlines said in a statement issued this morning.
Opande further stated that the families are more than willing to appear in court, and there are plans to facilitate them if they will be required to appear physically adding that the case may take long to be concluded. The FAA grounded the jets citing satellite tracking data that showed similarities between the Lion Air and Ethiopian crashes.
