Boeing must do more work on proposed 737 fix: US regulator

Black-box data indicates anti-stalling feature was engaged in Ethiopia crash official says

Data from the Indonesian plane indicates that pilots unsuccessfully fought the automated anti-stall system for control of the plane, which plunged into the sea shortly after takeoff.

It would also be disabled if two airflow sensors that measure the "angle of attack", or angle of the wing to the airflow, a fundamental parameter of flight, offered widely different readings, Boeing said last week.

"Safety is our first priority and we will take a thorough and methodical approach to the development and testing of the update to ensure we take the time to get it right".

Boeing and US aviation regulators say the company needs more time to finish changes in a flight-control system suspected of playing a role in two deadly crashes.

After that, the proposal will be submitted to a "rigorous safety review", the FAA spokesman said.

Nebiat initially said the report would be released Monday but the transport ministry, which is in charge of investigations, later said this would take several days.

Oil production and exports have declined steadily over the last few years, and there seems to be no end in sight to this freefall. Donald Trump has warned that all options are on the table to remove Russian troops.

No details were provided about exactly when the report would be released, or what it might contain.

The Boeing 737 Max went down shortly after take-off from Jakarta, killing all 189 people on board.

An investigation is underway and no official cause for the crash has been made public yet.

The finding based on data from the plane's flight recording black boxes is tentative, according to news reports, but the Ethiopian plane's erratic flight on March 10 resembles the problem a Lion Air flight in Indonesia experienced prior to crashing last October. The best way to recover is to put the plane's nose down, an attempt to pick up speed, and regain lift - but only as long as there's sufficient altitude to perform the maneuver.

Authorities are probing whether the system was a factor in the March 10 crash of the Ethiopian Airlines jet, which regulators said behaved similarly to the earlier downed plane.

"The subject accident occurred because, among other things, Boeing defectively designed a new flight control system for the Boeing 737 Max 8 that automatically and erroneously pushes the aircraft's nose down, and because Boeing failed to warn of the defect", according to the complaint.
