Boeing Co said on Friday it is addressing Indonesia’s safety recommendations following calls for better cockpit systems and oversight by U.S. regulators, and after the country blamed design flaws for a deadly Lion Air 737 MAX jet crash.
In its final report released on Friday, Indonesian regulators criticised the design of the anti-stall system known as MCAS, which automatically pushed the plane’s nose down, leaving pilots fighting for control.

Boeing said it has redesigned the way Angle of Attack (AoA) sensors work with the Manoeuvring Characteristics Augmentation System (MCAS).
“MCAS will now only turn on if both AoA sensors agree, will only activate once in response to erroneous AOA, and will always be subject to a maximum limit that can be overridden with the control column,’’ Boeing said.

On Oct. 29, 2018, a Lion Air 737 MAX jet crashed into the Java Sea shortly after take-off from Jakarta, killing all 189 people on board.
Boeing faces several investigations by regulators, U.S. Congress and the Department of Justice over its development of the 737 MAX, its previously best-selling workhorse for short-haul travel.
