Washington: US federal aviation authorities said on Monday they will order Boeing to modify its 737 MAX 8 aircraft, including anti-stalling software and maneuvering system updates, after two of the planes crashed in five months.
The Federal Aviation Administration told international civil aviation authorities that it "anticipates mandating these design changes... no later than April," although it did not ground the fleet.
Boeing is also set to update its training requirements and flight crew manuals to reflect the changes.
