"Boeing will conduct additional test and demo flights as we continue to work to demonstrate that we have identified and appropriately addressed all certification requirements. We will submit the update for FAA (Federal Aviation Administration) review once that work has been completed in the coming weeks", the statement read.
Earlier on Wednesday, the Federal Aviation Administration announced it had launched another review to ensure the safety of the Boeing 737 MAX.
A probe into the cause of the tragic events reportedly discovered that the anti-stall system on Boeing's new model could have been responsible for the fatal accidents. Ethiopia's Transport Ministry also stated that a report on the issue would be released on Thursday.
