Saudi ban on Boeing MAX flights to continue for near future: minister

Investigations have revealed what transpired in the final moments of an Ethiopian Airlines flight which crashed three weeks ago with the pilot making a last minute frantic radio call as the plane began nosediving downwards.

It was yet another blow to aviation giant Boeing, which just this week unveiled a fix to the Maneuvering Characteristics Augmentation System (MCAS) that Boeing created to prevent stalls in its new plane.

Ethiopia has already said there were "clear similarities" between the two MAX 8 crashes.

Acting FAA chief Daniel Elwell told Senate lawmakers an amended certificate had been given Boeing because the Max 8 and Max 9 were very similar to the company's older 737 models.

The lawsuit, filed on behalf of the estate of Ethiopian Airlines passenger Jackson Musoni of Rwanda, claims the 737 Max 8 isn't safely designed.

BBC reported that the flights crashed only six minutes into the flight.

"Earlier in March, a Boeing spokesperson said that the 737 Max was approved by the Federal Aviation Administration in accordance with standard procedures".

However, the same MCAS system was implicated in the October crash of a 737 MAX 8 airliner off Indonesia which left 189 people dead.

However, the source said the investigation is still underway and the findings are not yet definitive. Still, Garuda is sticking with Boeing and has asked the manufacturer for different aircraft.

The MCAS system is created to automatically point the nose of the jets down if it senses potential for a loss of lift, or aerodynamic stall.

The aircraft update is created to ensure the Maneuvering Characteristics Augmentation System will no longer repeatedly make corrections when a pilot tries to regain control.

In the Indonesia crash, initial investigations found problems with the MCAS system, when sensors of the plane's flight details sent wrong information.

USA pilots complained after the Lion Air crash that they had not been fully briefed on the system.

Boeing and the FAA declined to comment to AFP. Officials said pilots from various airlines are now testing the system in flight simulators.
