Boeing is set to brief hundreds of experts this morning on the 737 Max software update. But yet another problem may be plaguing this aircraft after a Southwest Airlines 737 Max 8 was forced to make an emergency landing yesterday.
The Southwest pilot called in that they had lost the right engine and needed to make an emergency landing. The aircraft was on its way to storage with no passengers on board but had to circle back to Orlando, Florida, with only the left engine running.
This software update was to be Boeing’s next step to get their 737 Max jets back into the air following the 2 deadly crashes that appear to involve the same problems shortly after take-off before hurling into an unrecoverable nose dive.
It is known that in the Indonesian crash of the 737 Max, the anti-stall system received bad data from one of its sensors and nosed the jet up and down 21 times. The pilots were fighting the up and down trajectory but did not ever turn off the anti-stall system.
The software update will require more data before the anti-stall safety system is triggered, and it will also make it easier for a pilot to recover with the aircraft nosing down only once.
The new software must first be certified by the Federal Aviation Administration (FAA), and it will be at least 2 more weeks before this possible certification by the FAA which will lift the grounding of the Boeing Max 737 fleet.
Currently, Southwest Airline’s fleet of 737 Max jets are parked in the High Desert in California during the world-wide grounding of this aircraft.
