Umshayeli wendiza, ohlonzwe kuphela ngokuthi 'u-Pilot X' emaphepheni asenkantolo, uvule icala lekilasi ngokumelene ne-Boeing, esola umenzi wendiza waseMelika ngokufihla inkinga yenzwa eyiphutha ye-737 MAX kanye nokugcina abashayeli bezindiza ebumnyameni mayelana nesici lapho befuna ukubuyisela okusheshayo.
Isenzo somthetho sihlanganiswe nabanye abashayeli bezindiza abangaphezu kuka-400, abaqeqeshelwe ukushayela indiza yesizukulwane sesine enomzimba omncane ongu-737 MAX. Basola inkampani yezindiza ezinze e-Chicago ngokuthulisa izinkathazo ezaziwayo mayelana nempahla egcwele ama-glitch efakwe kumajethi.
Inkinga enkulu ngamajethi igxile “ekuzibambeni okuyingozi ngokwemvelo kwe-aerodynamic” ye-Maneuvering Characteristics Augmentation System (MCAS), eklanyelwe ukuvimbela indiza ukuthi ingami. Ukusebenza kwayo okushelelayo kuncike kudatha eyitholayo kuzinzwa ezimbili ze-Angle of Attack (AoA). Kukhona okubili kwakho ngenxa yesizathu: uma idatha evela kuzinzwa ingafani, kufanele kukhanye isaziso se-AoA Ukungavumelani, sazise abashayeli bezindiza ngokungafani.
Ukuze lokhu kokugcina kusebenze kahle, isethi yokuzikhethela yezinkomba idinga ukufakwa endizeni, futhi amaphesenti angama-20 kuphela amajethi angama-737 MAX abenazo. UBoeing usanda kuvuma ukuthi uyazi ngale nkinga kusukela okungenani ngo-2017, kodwa akazange abikele i-US Federal Aviation Authority (FAA) kwaze kwaba yilapho indiza yeLion Air eyayinabantu abangu-189 iphahlazeka e-Indonesia ngo-Okthoba odlule. Ngaphezu kwalokho, ayizange ihlele ukuvuselela isofthiwe kuze kube ngu-2020.
Leli cala elifuna ukunxeshezelwa ngamaholo alahlekile kanye nokukhubazeka emqondweni abashayeli bamabhanoyi abakubekezelela ngenxa yokumiswa kwezindiza, lithi le nkampani yezindiza bekumele yazi ukuthi ngokuyishanela le ndaba, ibeka isisekelo salowo mphumela.
Isikhalazo sithi i-Boeing "ibambe iqhaza ekufihleni okungakaze kubonwe amaphutha edizayini eyaziwayo ye-MAX, okuholele ekuphahlazekeni kwezindiza ezimbili ze-MAX kanye nokumiswa kwazo zonke izindiza eziyi-MAX emhlabeni jikelele."
Abashayeli bezindiza “bayahlupheka futhi basaqhubeka nokuthola amaholo alahlekile, phakathi kokunye ukulimala kwezomnotho nokungekona kwezomnotho,” kusho yena.
Ukwengeza, abashayeli bezindiza basola i-Boeing ngokunikeza imiyalelo emincane yokuthi isingathwa kanjani isici esimelene nokuma, esishiwo kafushane kuphela kumanuwali endiza. Basola ukuthi indlela enjalo evamile yokujwayelanisa abashayeli bezindiza nge-software entsha yenziwe ngamabomu - futhi yayihloselwe ukonga izindleko zokwethula ukuqeqeshwa okusha okusekelwe kukulingisa ukuze abashayeli bezindiza bathathe “imizila engenisa imali ngokushesha okukhulu.”
Abamangali bathi inhloso yabo enkulu ukuvimbela izinhlekelele ezifana nezingozi zeLion Air kanye ne-Ethiopian Airlines, ezidlule nemiphefumulo engu-346, zingenzeki esikhathini esizayo ngokuvimba “iBoeing nabanye abakhiqizi bezindiza ekubekeni inzuzo yezinkampani ngaphambi kwezimpilo zabashayeli bezindiza. , izisebenzi, kanye nomphakathi jikelele abawusebenzelayo.”
Icala lizolalelwa yinkantolo yaseChicago ngo-Okthoba.
