Several airlines have grounded their Boeing 737 Max 8 jets following the crash of an Ethiopian Airlines flight on 10 March that killed all 157 people onboard.
The plane was bound for Nairobi, Kenya, but crashed six minutes after taking off from the Ethiopian capital, Addis Ababa.
The crash came only five months after the crash of an Indonesian Lion Air flight that also involved a Boeing 737 Max 8, which killed all 189 passengers.
US federal aviation authorities ordered Boeing to make improvements to its 737 Max 8 but did not ground the jet. The Federal Aviation Administration notified Boeing that it anticipates design changes, including anti-stalling software and manoeuvring system updates by April.
Ethiopian Airlines and Cayman Airways, along with Air China, China Eastern Airlines, China Southern Airlines have grounded their Boeing 737 Max 8 fleets.
The US-made aircraft was first launched in 2017 and has attracted more than 4,500 orders since, making it the fastest-selling aircraft in Boeing’s history. The twin-engine aircraft is popular because it is more fuel efficient than its predecessors.
