I-Boeing 737-800 yasungulwa ngemuva kokuphahlazeka kwase-China Eastern

I-China Eastern Boeing 737-800 iphahlazeke eningizimu yeChina namuhla (ngoMsombuluko, Mashi 21, 2022), kwashona bonke abangu-123 ababegibele i-MU5735 Ingabe kukhona ukuxhumana ne- I-Lion Air Flight 610 futhi I-Ethiopian Airlines B737 Max ukushayisana.

            Le ndiza enezinjini ezimbili, eyingxenye yomkhumbi ebisetshenziswa kusukela ngo-2015, kubikwa ukuthi yehlele endaweni eyihlathi ngemuva kwemizuzu ethile okungahambanga kahle kulandela ukutshuza isuka cishe ngamamitha angu-30,000, ngokusho kwe-FlightRadar24.com, iwebhusayithi yedatha yokulandela umkhondo wendiza. .

Ingabe i-Boeing 737-800 ne-737 MAX ziyefana?

I-737-800 iyimodeli endala. Ezinye izindiza bezishintshela ku-737-Max, indiza entsha enomzimba omncane. I-737-Max yamiswa okwesikhashana emhlabeni jikelele ngemuva kokuthi ezimbili zazo zaphahlazeka cishe eminyakeni emine edlule. I-737-Max igxekwe kakhulu ngemuva kokuthi enye yazo yaphahlazeka e-Indonesia ngasekupheleni kuka-2018 kwathi eyesibili yaphahlazeka e-Ethiopia.

I-China Eastern Airlines namuhla imise zonke izindiza zabagibeli ze-Boeing 737-800 kulandela ukuphahlazeka kwendiza #MU5735. Inkampani yezindiza inezingu-102 zalokhu okuhlukile kwezingu-737 - zonke manje sezimisiwe.

I-Boeing 737-800 ehilelekile ingenye yezindiza zezindiza ezidume kakhulu emhlabeni - ezingaphezu kuka-5,000 zalokhu okuhlukile (the -800) zilethwe yi-Boeing kumakhasimende ezindiza emhlabeni jikelele.

I-Boeing 737-800 indiza ngaphandle kwemikhawulo e-United States, Canada naseYurophu ngalesi sikhathi.

            "Kudingeka sazi ulwazi olwengeziwe ngaphambi kokuthi kwenziwe noma yiziphi iziphetho mayelana nalesi sigameko sengozi engazelelwe," kusho uRobert A. Clifford, umsunguli kanye nozakwethu omkhulu eClifford Law Offices eChicago osebenza njengoMeluleki Oholayo ekuqulweni kwamacala enkantolo yesifunda. Ukuphahlazeka kwe-Boeing ye-Ethiopian Airlines Flight 302 eyaphahlazeka eminyakeni emithathu edlule kule nyanga ngemuva nje kokusuka kwashona bonke abangu-157 ababegibele. “Lolu hlobo lokuphahlazeka kwendiza yeminyaka eyisithupha eyaklanywa futhi yagunyazwa ngawo-1990 aluvamile neze.”

            UClifford uqhube wathi imindeni yalabo abashonelwa izihlobo zabo engozini yakwa-ET302 iBoeing eminyakeni emithathu edlule isalindele umbiko wokugcina ovela kwiziphathimandla zase-Ethiopia ngembangela yaleyo ngozi. "Uma sicabanga ukuthi lo mbiko uyinhloso, ucwila ekujuleni kwesizathu, umbiko wase-Ethiopia uzokhombisa ukuthi inkampani yezindiza ebizwa nge-Boeing ngemuva kwengozi yokuqala ye-Boeing 737 MAX, futhi iziphathimandla azizange zitshelwe ngenkinga yohlelo lwe-MCAS obelungagwema. ingozi yesibili eyenzeka e-Ethiopia.”

            Inguqulo elandelayo ye-Boeing 737-900, i-MAX 8, kwakuyindiza entsha eyaphahlazeka oLwandle lwaseJava esuka e-Indonesia ngemva nje kokusuka ngo-Okthoba 2018, kwashona bonke abangu-189. Ezinyangeni ezinhlanu nje kamuva, enye i-737 MAX yaphahlazeka e-Ethiopia ehlanganisa abantu abavela emazweni angama-35 okuhlanganisa iMelika neCanada. I-Clifford Law Offices imele abantu abangaphezu kuka-70 kuleyo ndiza kuhlanganisa nabagibeli abane abavela ezweni laseChina kanye nomgibeli ovela eHong Kong kanye nesazi saseShayina esivela eCanada.

             Abaphenyi bathole ukuthi uhlelo olusha lwe-software, i-MCAS (Maneuvering Characteristic Augmentation System), lapho abashayeli bezindiza bengatshelwanga noma baqeqeshwe, kwakuyimbangela yalokho kuphahlazeka okubili. 

I-MCAS yenzani?

I-MCAS, noma i-Maneuvering Characteristics Augmentation System, inikeza izici ezingaguquki zokuphatha indiza kusethi ecacile kakhulu ye izimo zendiza ezingavamile. I-MCAS manje iqukethe ukuvikeleka okuthuthukisiwe okuningi:

• Izilinganiso ezivela kuzinzwa ezimbili ze-Angle of Attack (AOA) zizoqhathaniswa.
• Inzwa ngayinye izohambisa idatha yayo kukhompuyutha yokulawula ukundiza yendiza.
• I-MCAS izosebenza kuphela uma zombili izinzwa zivuma.
• I-MCAS izovulwa kanye kuphela.
• I-MCAS ayisoze yabhala ngaphezulu ikhono lomshayeli wendiza lokulawula indiza esebenzisa ikholomu yokulawula yedwa.

Ukuqulwa kwecala lamajaji obugebengu kuyaqala namuhla

Icala lejaji liqala namuhla eTexas ngokumelene nowayengumshayeli wendiza oyinhloko we-Boeing uMark Forkner obekwe icala lokulawula ukuphepha okudukisayo nezinkampani zezindiza mayelana ne-737 Max kanye nokusebenzisa ulwazi lwakhe lomsebenzi we-Federal Aviation Administration (FAA) ukukhohlisa i-ejensi ukuthi yehlise ukuqeqeshwa. izidingo zabashayeli bezindiza. I-FAA iqinisekisa izindiza zokundiza.

            Izitatimende zokuvula zenziwe ngoLwesihlanu ngabashushisi abathi uForkner akazange ayazise i-FAA mayelana nezinguquko emzamweni wokusindisa i-Boeing engamakhulu ezigidi zamaRandi umkhiqizi wendiza ebengawachitha ekubambezelekeni kokulethwa kanye nokunxephezela izindiza ekuqeqesheni umshayeli wendiza mathupha. .
