Boeing annunciate overnight that the party would secrete a software update for its 737 Max planes “ no later ” than next calendar month . The announcement , which was posted to Boeing’swebsite , calls the software release an “ enhancement ” and excuse that it ’s related to to the October crash of Lion Air Flight 610 which kill 189 people . Sunday ’s crash thatkilled 157 in Ethiopia is only cite in passing .
Both the Lion Air clangour and the Ethiopian Airlines clangoring occurred with the 737 Max-8 airplane , but Boeing ’s software system update looks like for all planes in the Max pipeline . There ’s concern among aviation expert that the two wreck may be related to automation of escape control system in the plane , but the investigation into what caused Sunday ’s crash is still in its other stages .
Southwest Airlines is presently operating 34 of the 737 Max-8 plane , while American Airlines presently flies 24 of the Max-8 aircraft . United Airlines does n’t fell the Max-8 , though it does have 14 of the Max-9 in its fleet .
From the Boeingpress release :
For the past several month and in the consequence of Lion Air Flight 610 , Boeing has been develop a flight control condition software program enhancement for the 737 MAX , design to make an already safe aircraft even safer . This include updates to the Maneuvering Characteristics Augmentation System ( MCAS ) flight control law of nature , pilot displays , operation manuals and crew training . The enhanced flight control jurisprudence incorporate slant of onslaught ( AOA ) inputs , point of accumulation stabiliser trim mastery in response to an erroneous angle of blast reading , and provides a limit to the stabilizer bid for retain elevator authority .
The Boeing announcement insists that pilot film are “ always ” capable to override erroneous mechanisation , something that has been a chief concern for those enquire the Lion Air smash . It ’s believed that the plane may have force its own olfactory organ down too far in an effort not to stall and that the pilot was unable to even out for thefalse reading material .
From Boeing :
A auction pitch augmentation control condition constabulary ( MCAS ) was implemented on the 737 MAX to improve aircraft manage equipment characteristic and lessen pitch - up tendency at lofty slant of attack . It was put through flight testing as part of the corroboration process prior to the airplane entering inspection and repair . MCAS does not see to it the plane in normal flight ; it ameliorate the behaviour of the airplane in a non - normal part of the operating envelope .
Boeing ’s 737 MAX Flight Crew Operations Manual ( FCOM ) already outline an existing procedure to safely wield the improbable event of erroneous data coming from an angle of attack ( AOA ) sensing element . The pilot will always be able to override the flight control law using electric trim or manual trim . In addition , it can be controlled through the use of the existing runaway stabilizer procedure as reinforced in the Operations Manual Bulletin ( OMB ) egress on Nov. 6 , 2018 .
Gizmodo has attain out to Boeing for more detail but did not directly get a answer . As Boeing remark in its press release , the Federal Aviation Administration ( FAA ) is n’t mandating any variety of actionright now . But the company says it expects the FAA to mandate the software upgrade through an “ Airworthiness Directive ( advertizement ) no afterwards than April . ”
What Boeing does n’t remark is that air expert are raising the alarm clock in a way that is uncharacteristic for their profession . The typical “ wait and see ” approach has proceed out the window , even among veteran veteran who never want to cause a panic .
“ U.S. FAA ought to crunch the fleet worldwide , ” FAA Chief of Staff Michael Goldfarb said on BBC TVyesterdaybefore the FAA made its annunciation that it would not be occupy any action .

“ Chances are this clangoring is n’t exactly what the Lion Air crash is , but I ’ve never seen such seasoned oldtimer investigators , to a person , speculate … speculate , which we ’re not supposed to do , and say ‘ this has the profile of the Lion Air clash . ’ ”
Australia and Singaporejoinedthe growing list of countries that have grounded their Boeing 737 Max airplanes overnight . China and Indonesia were the first to ground the aeroplane after Sunday ’s crash .
The conclusion by Australia was really a turn around of what it had said earlier in the day , insisting that it would hold off for steering from the FAA . After the FAA contribute the Boeing plane the all - light , Australian air travel authorities still settle to ground the planes .
Meanwhile , passenger in the U.S. are take to social sensitive to express their displeasure about potentially flying on Boeing 737 Max planes . But they might not have any resort .
“ Travelers can cancel their flights , but would not be eligible to take compensation if they determine to do so , ” Henrik Zillmer , the chief executive of AirHelp , told theNew York Times . “ They do not have a right to compensation or reimbursement for tickets purchased as it is technically their decision to cancel . ”
