ISebe lezoBulungisa lase-US liyakwandisa uphando lwalo lwe-Boeing, liphonononga izityholo zokuba imveliso ye-787 Dreamliner yathwaxwa kukungakwazi ukwenza umsebenzi okwakhokelela ekugwetyweni i-737 MAX kwaye yakhokelela kumakhulu okusweleka.
Abatshutshisi bomdibaniso bacele iirekhodi ezinxulumene ne-787 Dreamliner kwimveliso ye-Boeing's South Carolina, apho imithombo emibini ethethe ne-Seattle Times yathi kukho izityholo "zomsebenzi ongekho mhle." Umthombo wesithathu uqinisekisile ukuba umqeshwa ngamnye kwisityalo saseCharleston ufumene iisamani ekuqaleni kwale nyanga ukusuka “kwiqela elinye” labatshutshisi abaqhuba uphando oluqhubekayo kwi-737 MAX.
I-Boeing ikwisitulo esishushu ngenxa yomgangatho ophantsi womsebenzi kunye neekona zokusika kwisityalo saseMzantsi Carolina. Abatshutshisi kusenokwenzeka ukuba banenkxalabo malunga nokuba "iingxaki zenkcubeko ezibanzi" zityhutyha yonke inkampani, kubandakanya noxinzelelo lomsebenzi ongeyonyani ukuze kuhanjiswe iinqwelomoya kwangexesha, omnye umthombo uxelele iSeattle Times. Isityalo saseMzantsi Carolina senze iipesenti ezingama-45 zeBoeing's 787s kulo nyaka uphelileyo, kodwa imodeli yayo ephezulu -10 yakhiwe apho kuphela.
Abatshutshisi bazingela "iimpawu zobuqhetseba zakudala," utshilo umthombo, njengokuxoka okanye ukumela kakubi abathengi kunye nabalawuli. Iimpempe kumzi-mveliso waseCharleston abalatha kububutyobo kunye nezixhobo ezishiywe e-injini, kufutshane neengcingo, nakwezinye iindawo ezinobuzaza ezinokuthi zibangele imiba yokusebenza baxelele iNew York Times ukuba bohlwaywa ngabaphathi, kwaye abaphathi baxela ukuba batyhalwe ukuba bavuthulule. iinqwelomoya ziphuma ngokukhawuleza kwaye zigqume ukulibaziseka.
I-737 MAX, nayo, yaleqiswa kwintengiso phakathi kokunqunyulwa kwekona ukuze ibethe umntu okhuphisana naye imodeli entsha ye-Airbus. Okubi nakakhulu, i-Federal Aviation Administration kuthiwa ivumele i-Boeing ukuba iqhube iitshekhi ezininzi ezikhuselekileyo zokhuseleko ngokwayo, kwaye abalawuli bamanye amazwe bathatha isatifikethi sokhuseleko sase-US njengobungqina bokuba akukho mfuneko yokuba baqhube iitshekhi zabo, oko kwaphumela kwiintlekele ze-Lion Air kunye ne-Ethiopian Airlines. Oktobha noMatshi.
Inkqubo ebalulekileyo yokucima umlilo kwi-Dreamliner yafunyaniswa ingasebenzi kakuhle ekuqaleni kwale nyanga, nto leyo eyakhokelela ekubeni uBoeing akhuphe isilumkiso sokuba isitshixo esenzelwe ukucima imililo ye-injini asiphumelelanga “kwezinye iimeko.” Ngelixa i-FAA ilumkise ukuba "amandla akhona ukuba umlilo wenqwelomoya ungalawuleki," bakhetha ukungazisi phantsi ii-787s, endaweni yoko bayalela iinqwelomoya ukuba zijonge ukuba utshintsho lusebenza rhoqo ngeentsuku ze-30.
I-DoJ kunye ne-Inspector General yeSebe lezoThutho bavula uphando lwabo kwi-Boeing 737 MAX emva kokuba inqwelomoya yokuqala yaphahlazeka e-Indonesia ngo-Oktobha, ibulala wonke umntu owayekhwele; i-FBI yajoyina uphando ngo-Matshi emva kokuba indiza yesibini yehla e-Ethiopia phantsi kweemeko ezifanayo. Ibiza ukusungulwa kophando emva kwengozi enye “engaqhelekanga kakhulu,” omnye wemithombo ye-Seattle Times ucebise ukuba umntu onolwazi lwangaphakathi uze ngaphambili nobungqina malunga nonobangela wengozi, ethe yalandwa kwiziphene kwinqwelomoya kwi-MCAS. inkqubo yekhompyuter.
U-Boeing akakamangalelwa ngolwaphulo-mthetho malunga nokuba yeyiphi ingozi, kodwa izimangalo ezichasene nenkampani, kubandakanywa isimangalo senqanaba elinye ngabaqhubi beenqwelomoya abangaphezu kwama-400 abatyhola inkampani ukuba igqubuthele iziphene kwinkqubo yayo ye-MCAS, iyafumba kwaye imiyalelo yeenqwelomoya zayo ziye zagcwala. yehle yaya kutsho ku-zero njengoko iinqwelomoya kwihlabathi jikelele ziye zamisa i-737 MAX kwiinyanga ezintathu ezidlulileyo. Kwangoko kule nyanga, i-FAA ifumene ngakumbi "imingcipheko enokubakho" ekufuneka ijongiwe ngaphambi kokuba i-737 MAX ibuyele ekubhabha.
