Seattle, Washington - Boeing halted deliveries of the 737 MAX jets after the global grounding of the type on March 13 and reduced the production rate by 20% to 42 aircraft per month.
Boeing has been working on a software fix for a while to gain the approval of global civil aviation regulators and return the aircraft to the service.
In both crashes, one in Indonesia in October 2018 and one in Ethiopia in March 2019, the pilots were battling the anti-stall prevention system known as MCAS (Maneuvering Characteristics Augmentation System), which was activated due to false AOA (Angle of Attack) data from one of the two sensors located in front of the aircraft.
Boeing has modified the system to verify AOA data from both sensors before MCAS intervenes to correct the aircraft's angle of attack.
The FAA (Federal Aviation Administration) and EASA (European Aviation Safety Agency) are currently conducting their own checks before allowing the aircraft to fly again.
Many International regulators are waiting for the FAA's or EASA's approval to resume their flight schedules with the 737 MAXs.
The FAA is following a thorough process for returning the Boeing 737 Max to passenger service,
the agency said in a statement.
We continue to work with other international aviation safety regulators to review the proposed changes to the aircraft.
Boeing has completed a simulator test with the FAA in a simulator, one of five tasks required to return the plane to service. Live flight tests will follow soon.
The grounding of the aircraft has hindered the growth of the 737 MAX operators and customers and cost them hundreds of millions of dollars.
Boeing accepted to pay compensation for the 737 MAX operators and customers for the canceled flights and delivery delays.
