Uthini uBoeing emva kwengxelo yengozi yeLion Air Flight 610?
Ikhuseleke kangakanani iBoeing 737 Max. Lo ibingumbuzo osoloko ubuzwa emva I-Lion Air kwingozi ebulalayo yase-Indonesia nangaphezulu emva kokuba ingxelo yamva nje ifumene ukuba i-Boeing ayiphumelelanga ukubhaqa impazamo yesoftware ebangele ukuba isibane esilumkisayo singasebenzi kwaye basilele ukunika abaqhubi ulwazi malunga nenkqubo yolawulo lokubhabha.
Isizathu sokuba abantu be-189 bafe kwi-Lion Air yayinento yokwenza noyilo lwe-Boeing, ukugcinwa kwe-jet kunye neempazamo zomqhubi wenqwelomoya ezibe negalelo kwintlekele.
namhlanje iBoeing ikhuphe ingxelo elandelayo malunga nokukhutshwa namhlanje kwengxelo yokugqibela yophando yeLion Air Flight 610 yiKomiti yeSizwe yoKhuseleko lwezoThutho yase-Indonesia (KNKT):
“Egameni lakhe wonke umntu e-Boeing, ndifuna ukudlulisa uvelwano lwethu olunzulu kwiintsapho nakwizintandane zabo baphulukene nobomi babo kwezi ngozi. Sizilile kunye neLion Air, kwaye singathanda ukuvakalisa uvelwano lwethu olunzulu kusapho lweLion Air,” utshilo uMongameli weBoeing kunye ne-CEO uDennis Muilenburg. "Ezi ziganeko zibuhlungu zisichaphazele ngokunzulu sonke kwaye siya kuhlala sikukhumbula okwenzekileyo."
“Siyayincoma iKomiti yeSizwe yoKhuseleko lwezoThutho yaseIndonesia ngemigudu yayo emikhulu yokufumanisa izibakala ngale ngozi, izinto ezifak’ isandla kunobangela wayo kunye neengcebiso ezijoliswe kwiinjongo zethu ezifanayo zokuba ingaphindi yenzeke le nto.”
“Sijongana nezindululo zokhuseleko ze-KNKT, kwaye sithatha amanyathelo okomeleza ukhuseleko lwe-737 MAX ukuthintela iimeko zolawulo lwenqwelomoya ezenzeke kule ngozi ukuba ingaphindi yenzeke. Ukhuseleko lixabiso elihlala lihleli kuye wonke umntu e-Boeing kwaye ukhuseleko loluntu olubhabhayo, abathengi bethu, kunye nabasebenzi abakwinqwelomoya yethu ihlala iphambili kuthi. Siyixabisile intsebenziswano yethu ekudala ikho neLion Air kwaye sijonge phambili ekuqhubekeni sisebenza kunye kwixesha elizayo.”
Iingcali ze-Boeing, ezisebenza njengabacebisi bezobuchwepheshe kwiBhodi yoKhuseleko lwezoThutho yeSizwe yase-US, baye baxhasa i-KNKT ngexesha lophando. Iinjineli zenkampani zisebenza kunye ne-US Federal Aviation Administration (FAA) kunye nabanye abalawuli behlabathi ukwenza uhlaziyo lwesoftware kunye nolunye utshintsho, kuthathelwa ingqalelo ulwazi oluvela kuphando lwe-KNKT.
Ukusukela kule ngozi, i-737 MAX kunye nesoftware yayo iphantsi kwenqanaba elingazange libonwe ngaphambili lolawulo lwehlabathi jikelele, uvavanyo kunye nohlalutyo. Oku kubandakanya amakhulu eeseshoni ze-simulator kunye neenqwelomoya zokuvavanya, uhlalutyo lolawulo lwamawakawaka amaxwebhu, ukuphononongwa ngabalawuli kunye neengcali ezizimeleyo kunye neemfuno ezibanzi zesitifiketi.
Kwiinyanga ezimbalwa ezidlulileyo uBoeing wenze utshintsho kwi-737 MAX. Okona kubaluleke kakhulu, i-Boeing iphinde yaqulunqa kwakhona indlela i-Angle of Attack (AoA) esebenza ngayo i-sensor ye-flight control software eyaziwa ngokuba yi-Maneuvering Characteristics Augmentation System (MCAS). Ukuqhubela phambili, i-MCAS iya kuthelekisa ulwazi kuzo zombini iisenso ze-AoA ngaphambi kokuba isebenze, yongeza umaleko omtsha wokhuseleko.
Ukongeza, i-MCAS ngoku iya kuvulwa kuphela ukuba zombini ii-sensor ze-AoA ziyavuma, ziya kusebenza kube kanye kuphela ekuphenduleni i-AOA ephosakeleyo, kwaye iya kuhlala ixhomekeke kumda ophezulu onokugqithiswa kwikholamu yolawulo.
Olu tshintsho lwesoftware luya kuthintela iimeko zolawulo lwenqwelomoya ezenzeke kule ngozi ukuba ingaphindi yenzeke kwakhona.
Ukongeza, iBoeing ihlaziya iimanyuwali zabasebenzi kunye noqeqesho lomqhubi wenqwelomoya, eyilelwe ukuqinisekisa ukuba umqhubi ngamnye unalo lonke ulwazi aludingayo ukuze abhabhe ngokukhuselekileyo i-737 MAX.
I-Boeing iyaqhubeka nokusebenza kunye ne-FAA kunye nezinye ii-arhente ezilawulayo kwihlabathi jikelele kwisiqinisekiso sohlaziyo lwesoftware kunye nenkqubo yoqeqesho ukubuyisela ngokukhuselekileyo i-737 MAX kwinkonzo.
