Iwo omwe amatsatira zomwe zikuchitika pamakampani oyendetsa ndege akudziwa za chipongwe chomwe chikuchitika mozungulira Boeing 737 Max. Ndege yaposachedwa kwambiri ya kampani yotchuka yaku America ya Boeing inali ndi zovuta zingapo zoyambirira zomwe zimayambitsidwa ndi mapangidwe a ndege zakale komanso nthawi zambiri (zopangidwa kuyambira 1967). Injini zatsopano zamphamvu komanso zogwira mtima kwambiri zinali zazikulu komanso zolemetsa poyerekeza ndi zomwe zidagwiritsidwa ntchito kale 737 NG chitsanzo ndipo, atasunthidwa kutali ndi mapiko, adapanga torque yamphamvu yokhotakhota, kukweza mphuno ya ndege powonjezera kukankhira. Kuonjezera apo, pamene ngodya ya kuukira ikuwonjezeka, amalepheretsa kutuluka kwa mpweya kumapiko, zomwe zimachepetsa kwambiri kukweza ndipo ndizoopsa kwambiri.
Kuti agwiritsebe ntchito injini zatsopano pamodzi ndi mapangidwe akale, kampaniyo inabwera ndi MCAS (Maneuvering Characteristics Augmentation System) dongosolo, lomwe lapangidwa kuti lithandize mwakachetechete woyendetsa ndege kuwongolera ndegeyo mumayendedwe apamanja (pamene autopilot yazimitsidwa) . Pamene mbali ina ya kuukira idutsa (kutengera kuwerengera kwa masensa awiri), ndegeyo imapita kumadzi.
Vuto ndiloti masensa atha kukhala olakwika, ndipo MCAS idalembedwa molakwika kwambiri, kotero oyendetsa ndegewo samadziwa za kukhalapo kwake (palibe chomwe chidanenedwa kwa ogwira ntchito pomwe makinawo adayatsidwa). Kuphatikiza apo, monga momwe zidakhalira, dongosololi lidawerengera kuchokera ku sensa imodzi yokha. Akukhulupirira kuti inali ntchito yolakwika ya MCAS yomwe idawononga Indonesia Max mu Okutobala ndikubweretsa tsoka lofananalo ku Ethiopia mu Marichi, pambuyo pake Boeing adakakamizika kuyimitsa kupanga Boeing 737 Max.
Tsopano gwero lovomerezeka The Wall Street Journal, potchula magwero ake, linanena kuti wopanga ndege waku America ali wokonzeka kuyika zosintha zazikulu zomwe zidakonzedwa kuti zikonze zolakwika za dongosolo la MCAS. Komabe, pali mafunso okhudza momwe dongosolo lotereli linatsimikizidwira poyamba. Mtsogoleri wakale wa US National Transportation Safety Board (NTSB) amakhulupirira kuti chiphaso cha ndege ku US Federal Aviation Administration (FAA) m'zaka zaposachedwa chinachitika pafupifupi ndi ogwira ntchito opanga ndege okha, osayang'ana zolakwika.
Tsopano ndege za 737 Max zilibe ntchito padziko lonse lapansi, ndipo ndege zikuwonongeka. Bungwe la FAA akuti lapereka kale chivomerezo pakusintha komwe Boeing akufuna, zomwe zikuyenera kupewa ngozi zazikulu ngati izi. Izi zikuphatikiza zosintha zamapulogalamu zomwe zingafewetse MCAS kuti oyendetsa ndege athe kuthana nazo (m'malo mozungulira). Kusinthaku kudzafunikanso kuti MCAS iganizire zambiri kuchokera ku masensa awiri, osati imodzi yokha, yomwe ingakhale yolakwika, monga momwe zinalili pa ngozi ya October.
Kuphatikiza apo, Boeing ipereka maphunziro owonjezera kwa oyendetsa ndege kuti ayendetse ndege yatsopanoyi, zomwe poyamba sizinali zofunikira. Bungwe la FAA linanena kale kuti 737 Max ili ndi mawonekedwe ofanana ndi oyendetsa ndege akale a 737 ndipo safuna maphunziro owonjezera. Tsopano bungwe la FAA likuimbidwa mlandu chifukwa cha kulephera komwe kunapangitsa kuti mazana ambiri awonongeke. Koma ngakhale zosinthazi zitavomerezedwa, zidzatenga milungu ingapo kukonzanso mapulogalamu a ndege zonse zopangidwa ndi miyezi kuti ziyende bwino. Ndipo izi zili ku USA kokha. Othandizira a FAA ku Canada ndi European Union azifufuza okha, kuphatikiza chiphaso cha FAA cha ndege yomwe ili ndi vuto.
Nthawi zambiri, Boeing tsopano akuvutika kwambiri zachuma komanso mbiri. Patsamba lake lovomerezeka, kampaniyo inanena kuti 737 Max ndi ndege yogulitsidwa kwambiri m'mbiri yake: kampaniyo yalandira kale maoda a 5000 kuchokera kwa makasitomala 100 padziko lonse lapansi. Ndani akudziwa - mwina kampaniyo iyenera kupitiliza kupanga m'badwo wakale wa B737-NG, womwe umayenera kutha kumapeto kwa chaka chino.
