Sibike izinkinga nge-MCAS (Maneuvering Characteristics Augmentation System), eklanyelwe ukusiza abashayeli bezindiza buthule ukuthi bandize indiza ye-Boeing 737 Max ngemodi eyenziwa ngesandla (uma umshayeli wendiza ozenzakalelayo uvaliwe). Kukholakala ukuthi nguye owaholela ezingozini ezimbili zokugcina zendiza ngalo mshini. Muva nje, i-US Federal Aviation Administration (FAA) ithumele isiqeshana sesofthiwe esidalwe ochwepheshe be-Boeing ukuze sibuyekezwe, ukuze izindiza zingasuki isikhathi eside ngisho naseMelika. Kumanje uphenyo lusaqhubeka mayelana nokuphahlazeka kweBoeing yase-Ethiopia ngoMashi 10, kanti abeReuters, becaphuna imithombo yabo, babike ukuthi uhlelo lwe-MCAS luphinde lwasebenza ngemuva kokuthi abashayeli bezindiza belucishile, base befaka indiza endaweni yokucwila.
Imithombo emibili ithe umbiko wokuqala wase-Ethiopia mayelana nengozi kufanele ukhululwe zingakapheli izinsuku futhi ungafaka nobufakazi bokuthi uhlelo lwe-MCAS lwenziwe lwasebenza izikhathi ezine ngaphambi kokuba i-737 Max ishaye phansi. Umthombo wesithathu utshele izintatheli ukuthi isoftware iphinde yaqala ukusebenza ngemuva kokuthi abashayeli bezindiza beyicishile, kodwa wengeza ngokuthi kunesiqephu esisodwa esibalulekile lapho i-MCAS ifake khona indiza ngaphambi kokuphahlazeka. Kusolwa ukuthi isoftware yaqala ukusebenza futhi ngaphandle kokungenelela komuntu.
Esitatimendeni esithunyelwe izintatheli ngale datha, u-Boeing uthe: "Sinxusa ukuqapha futhi singacabangi noma sifinyelele iziphetho mayelana nemiphumela ngaphambi kokuthi kukhishwe idatha yendiza kanye nombiko wokuqala." Uhlelo lwe-MCAS njengamanje luphakathi kwehlazo elimayelana nokuphahlazeka kwe-Ethiopian Flight 302 kanye nengozi yeLion Air e-Indonesia ezinyangeni ezinhlanu ezedlule - izingozi ezashona abantu abangu-346 sebebonke.
Izibalo ziphezulu: I-Boeing 737 Max iyindiza ethengiswa kakhulu yenkampani, enama-oda acela ku-5000 kakade. Futhi manje iqoqo lezindiza ezidayisiwe lisaqhubeka nokuhlala lingenzi lutho emhlabeni jikelele. Ukuqaliswa kabusha kwezindiza kuncike endimeni eyadlalwa umklamo wendiza ekuphahlazekeni, nakuba abaphenyi bephinde babheke izenzo zezinkampani zezindiza, abasebenzi kanye nezinyathelo zokulawula. I-Boeing ibheke ukuthuthukisa isofthiwe yayo ye-MCAS futhi yethule izinhlelo ezintsha zokuqeqesha umshayeli.
Ngaphambilini kubikwe ukuthi kuzo zombili izingozi inkinga ingase ihlobane nokusebenza okungalungile kwe-MCAS, eyayiqondiswa i-angle eyiphutha yedatha yokuhlasela evela kwenye yezinzwa ezimbili zendiza. Manje uphenyo kuthiwa seluphethe ngokuthi endabeni yase-Ethiopia, i-MCAS ekuqaleni yakhutshazwa kahle ngabashayeli bezindiza, kodwa yabe isiqala kabusha ukuthumela iziyalezo ezizenzakalelayo ku-stabilizer, okwafaka indiza ekujuleni.
Ngemuva kwengozi yase-Indonesia, i-Boeing ikhiphe imiyalelo kubashayeli bezindiza echaza inqubo yokuvala i-MCAS. Kudinga ukuthi ngemva kokuvala shaqa futhi kuze kube sekupheleni kwendiza izisebenzi zingaluvuli lolu hlelo. I-Wall Street Journal ngaphambilini yabika ukuthi abashayeli bezindiza baqale balandela izinqubo eziphuthumayo ze-Boeing kodwa babuye bazilahla njengoba bezama ukuphinde balawule indiza. Ukukhubaza uhlelo kuthiwa akuvimbi ngokuphelele i-MCAS, kodwa kwephula uxhumano phakathi kwesofthiwe, eqhubeka nokukhipha imiyalelo engalungile ku-stabilizer, nokulawula kwangempela kwendiza. Abacwaningi manje bayaphenya ukuthi ingabe zikhona yini izimo lapho i-MCAS ingaphinda isebenze ngaphansi kwazo ngaphandle kolwazi lwabashayeli bezindiza.
Umhlaziyi u-Bjorn Fehrm uphakamise kubhulogi yakhe ukuthi abashayeli bezindiza kungenzeka bahlulekile ukususa mathupha isiqinisi endaweni yokutshuza. Ngakho-ke kungenzeka ukuthi banqume ukuvuselela i-MCAS ukuze bazame ukwenza isizinzisi sibe sesimweni, futhi uhlelo luvele lungabavumeli bakwenze. Ochwepheshe bezokuphepha, nokho, bagcizelela ukuthi uphenyo kusekude ukuba luphele, futhi izingozi eziningi zezindiza zidalwa inhlanganisela yezinto ezithinta abantu kanye nezobuchwepheshe.
