The new approach, meant to make the Max more reliable, also guards against the risk that a processing error or chip failure could send an erroneous reading to the flight controls, according to the report. It will check for any disagreements in the sensor readings, the Seattle Times said. Boeings 737 Max MCAS flight control system has been cited as the cause of two crashes, in Indonesia and Ethiopia, that killed 346 passengers and crew. Under the changes now being planned for the configuration, the flight-control system will read inputs and outputs from both of a jet’s computers for a range of sensors monitoring airspeed, altitude and the angle of the aircraft’s wings against the air stream. The Federal Aviation Administration, under fire for certifying the Max, uncovered the issue while testing theoretical failures in a new system-safety analysis of the Max’s flight controls.

The change to the software architecture for the grounded jetliner was reported earlier by the Seattle Times, which detailed Boeing’s response to a fault flagged by US regulators in June.

The latest approach is more comprehensive than a software update Boeing has been preparing to address a system linked to two fatal crashes. The US planemaker is still aiming to present a final software package to regulators by September, though the timeline could slip, said the person, who asked not to be named because the plans are private. is redesigning the flight-control system of the grounded 737 Max to rely on data from both of the jetliner’s flight-control computers instead of just one, said a person familiar with the plans. The aircraft was a Boeing 737 MAX8.Chicago: Boeing Co. Mohammad bin Nasser Al Zaabi, Executive President of the Public Authority for Civil Aviation, was quoted in Times of Oman saying that safety of people’s lives was their top priority and led them to take the decision, following the deadly Lion Air Flight 610 crash, which killed all 189 passengers and crew in October 2018 and the Ethiopian Airlines crash, which claimed the lives of all 157 people on board. This software change is an addition to the already announced changes that will take input from both angle-of-attack sensors in the MCAS anti-stall system linked to two deadly crashes that led to a global grounding of the plane, including in Oman where the Public Authority for Civil Aviation suspended all Boeing 737 MAX aircraft operating into and out of the country’s airports until further notice. The FFA had clearly stated then that the new issue will have to addressed and resolved before the plane could be ungrounded.Īccording to sources, Boeing still plans to complete the software redesign to submit it to the FAA by end of September for approvals.īoeing Chief Executive Dennis Muilenburg told analysts last month that he was confident the 737 Max would be back in service as early as October after a certification flight in “the September time frame.”

The redesign, which was first reported by the Seattle Times, is said to involve using and receiving input from both flight control computers rather than one and is in response to a problem discovered during a Federal Aviation Administration (FAA) simulator test.
