Uthini uBoeing ngemuva kombiko wokuphahlazeka kweLion Air Flight 610?

Iphephe kangakanani i-Boeing 737 Max. Lona kwakungumbuzo owawubuzwa njalo ngemva kwalokho I-Lion Air engozini ebulalayo yase-Indonesia futhi nangaphezulu ngemva kokuba umbiko wakamuva uthole ukuthi i-Boeing yehlulekile ukubona iphutha le-software eliholele ekutheni isibani esiyisixwayiso singasebenzi futhi yehlulekile ukunikeza abashayeli bezindiza ulwazi mayelana nesistimu yokulawula indiza.

Isizathu sokuthi abantu abangu-189 bafe e-Lion Air sasihlobene nomklamo we-Boeing, ukunakekelwa kwendiza yendiza kanye namaphutha omshayeli abe nomthelela enhlekeleleni.

Namuhla Boeing ikhiphe isitatimende esilandelayo mayelana nokukhishwa namuhla kombiko wokugcina wophenyo we-Lion Air Flight 610 yiKomidi Likazwelonke Lezokuphepha Ezokuthutha lase-Indonesia (KNKT):

“Egameni lawo wonke umuntu kwa-Boeing, ngifuna ukudlulisa amazwi enduduzo emindenini nakubantu esibathandayo abalahlekelwa izimpilo zabo kulezi zingozi. Siyalila neLion Air, futhi sithanda ukuzwakalisa ukuzwelana kwethu okukhulu nomndeni wakwaLion Air,” kusho uMongameli weBoeing kanye ne-CEO uDennis Muilenburg. "Lezi zigameko ezibuhlungu zisithinte kakhulu sonke futhi sizohlale sikukhumbula okwenzekile."

“Sincoma iNational Transportation Safety Committee yase-Indonesia ngemizamo yayo emikhulu yokuthola amaqiniso ale ngozi, izici ezibangela imbangela yayo nezincomo ezihloselwe emgomweni wethu ofanayo wokuthi lokhu kungaphinde kwenzeke.”

“Sibhekana nezincomo zokuphepha ze-KNKT, futhi sithatha izinyathelo zokuthuthukisa ukuphepha kwe-737 MAX ukuvimbela izimo zokulawula indiza ezenzeke kule ngozi ukuthi zingaphinde zenzeke. Ukuphepha kuyinani elihlala njalo lawo wonke umuntu kwa-Boeing futhi ukuphepha komphakathi endizayo, amakhasimende ethu, kanye nezisebenzi ezindizeni zethu kuhlala kuyinto ehamba phambili yethu. Siyalwazisa ubudlelwano bethu obunesikhathi eside ne-Lion Air futhi sibheke ngabomvu ukuqhubeka nokusebenza ndawonye esikhathini esizayo.”

Ochwepheshe be-Boeing, abasebenza njengabeluleki bezobuchwepheshe beBhodi Lezokuphepha Kuzwelonke lase-US, baye basekela i-KNKT phakathi nophenyo. Onjiniyela bale nkampani bebesebenza ne-US Federal Aviation Administration (FAA) kanye nabanye abalawuli bomhlaba wonke ukwenza izibuyekezo zesoftware nezinye izinguquko, kucatshangelwa imininingwane evela ophenyweni lwe-KNKT.

Kusukela kule ngozi, i-737 MAX kanye nesofthiwe yayo ingaphansi kwezinga elingakaze libonwe lokubhekwa, ukuhlolwa nokuhlaziywa kokulawulwa komhlaba wonke. Lokhu kuhlanganisa amakhulukhulu ezikhathi zokulingisa nezindiza zokuhlola, ukuhlaziya okulawulwayo kwezinkulungwane zamadokhumenti, ukubuyekezwa ngabalawuli nochwepheshe abazimele kanye nezidingo ezibanzi zesitifiketi.

Ezinyangeni ezimbalwa ezedlule i-Boeing yenze izinguquko ku-737 MAX. Okubaluleke kakhulu, i-Boeing idizayine kabusha indlela izinzwa ze-Angle of Attack (AoA) ezisebenza ngayo ngesici sesofthiwe yokulawula indiza eyaziwa ngokuthi i-Maneuvering Characteristics Augmentation System (MCAS). Ukuqhubekela phambili, i-MCAS izoqhathanisa imininingwane evela kuzo zombili izinzwa ze-AoA ngaphambi kokuthi isebenze, yengeze isendlalelo esisha sokuvikela.

Ngaphezu kwalokho, i-MCAS manje izovula kuphela uma zombili izinzwa ze-AoA zivuma, zizokwenza kusebenze kanye kuphela ekuphenduleni i-AOA enephutha, futhi iyohlala ingaphansi komkhawulo omkhulu ongabhalwa phezu kwekholomu yokulawula.

Lezi zinguquko zesofthiwe zizovimbela izimo zokulawula indiza ezenzeke kule ngozi ukuthi zingaphinde zenzeke.

Ngaphezu kwalokho, i-Boeing ibuyekeza amamanyuwali ezisebenzi nokuqeqeshwa komshayeli wendiza, okuklanyelwe ukuqinisekisa ukuthi wonke umshayeli wendiza unalo lonke ulwazi aludingayo ukuze andize i-737 MAX ngokuphepha.

I-Boeing iyaqhubeka nokusebenzisana ne-FAA nezinye izinhlaka ezilawulayo emhlabeni wonke ekunikezeni isitifiketi sokuvuselelwa kwesofthiwe nohlelo lokuqeqesha ukuze kubuyiselwe ngokuphephile i-737 MAX enkonzweni.
