Owayesakuba yintloko yeBhodi yeSizwe yoKhuseleko lwezoThutho - i-arhente yaseMelika ephanda ngengozi yangoLwesine odlulileyo yenqwelomoya eyakhiwe eCanada kufutshane neBuffalo, NY - ithi zonke ii-turboprops zeenjini ezifanayo kufuneka zimiswe, ubuncinci de uphando lugqityiwe.
“Ndicinga ukuba eyona nto ilumkileyo yokwenza…
Olo phando ludla ngokuthatha ukusuka kwiinyanga ezili-18 ukuya kwiminyaka emibini, yaye uncomelo lukaHolo lunokubangela umonakalo, ekubeni amawaka ee-passenger turboprops asebenza ehlabathini lonke.
UHall uthe iinqwelomoya ezineenjini ze-turboprop zibhabha ngesantya esiphantsi kunejethi, nto leyo eyenza kube lula ukuba umkhenkce ufumbathe. Kwakhona wayegxeka iteknoloji ye-turboprop de-icing - "iibhutsi" zerabha ezizaliswe ngumoya ezandisayo kunye nenkontileka yokukhupha umkhenkce, endaweni yezifudumezi zangaphakathi ezisetyenziselwa iijethi ukugcina umkhenkce ungenzi.
Ukusukela oko kwehla ingozi ye-Continental Connection 3407 yabulala abantu abangamashumi amahlanu kwindawo yaseBuffalo eClarence ngoLwesine odlulileyo, umkhenkce ukhankanywe njengoyena nobangela, kodwa abaphandi beengozi abakayithethi ngokusesikweni.
Inqwelo-moya, i-74-seat Bombardier Q400 turboprop eyakhelwe eToronto kwaye yasungulwa ngo-Epreli odlulileyo, ikwinkonzo yehlabathi jikelele; Ama-219 asetyenziswa ngabathwali abangama-30, inxalenye yenqwelomoya yehlabathi ye-880 Bombardier-eyakhelwe i-Q-series turboprops esetyenziswayo.
Kodwa lincinci ithuba lokucetyiswa kweHolo iya kwenziwa, kuba i-US Federal Aviation Administration, enoxanduva lokhuseleko lokuphamba ngenqwelomoya, iyalikhaba icebiso lakhe.
“Asinayo idatha okwangoku enokukhokelela ekubeni siyibeke phantsi le nqwelomoya,” utshilo isithethi seFAA uLaura Brown.
“I-FAA kunye neshishini leenqwelomoya lonke lisebenze ngamandla kule minyaka ili-15 idlulileyo ukunciphisa iingozi ezinxulumene ne-icing kwaye ezo ngozi ziye zehla kakhulu ngenxa yaloo msebenzi.
"Inqwelo-moya ebandakanyekayo kwi-crash inenkqubo yokukhangela i-ice eyinkimbinkimbi kunye nenkqubo yokukhusela eyazuza kwiminyaka yophando kunye nohlalutyo malunga nendlela i-aircraft esebenza ngayo kunye nokusebenza kwiimeko ezibandayo," kusho uBrown.
I-Porter Airlines yaseToronto isebenzisa kuphela i-Q400 kwaye izolo uRobert Deluce, umongameli we-airline kunye negosa eliphetheyo, uncome irekhodi lokhuseleko lwenqwelomoya kunye nokunciphisa i-icing kunye ne-anti-icing technology. "Ukuba (ibhodi yokhuseleko) ibinenkxalabo, okanye ukuba i-FAA okanye i-Canada yezoThutho okanye i-Bombardier inenkxalabo malunga nenqwelomoya, naluphi na uhlobo, ibiya kusekwa ngoku," watsho.
Kodwa oku akuvakali ngathi nantoni na enxulumene nenqwelomoya. Oku kuvakala ngathi kunxulumene neminye imiba engekaphumi. ”
Abaphandi ngengozi bathi iFlight 3407, isuka eNewark isiya eBuffalo, yagxumeka yaza yaqengqeleka ngobundlobongela phambi kokuba iwele kumakhulu aliqela eemitha kwindlu ngoLwesine ebusuku, yabulala bonke abangama-49 ababekhwele kunye nendoda ebisendlini. Kule ngozi kwafa umntu waseKhanada. Izolo abantu abangaphezu kwe-2,000 bebeye kwisikhumbuzo e-US samaxhoba.
Ngaphambi kokuba abasebenzi abantlithekayo banike ingxelo "yokukhenkceza okubalulekileyo," emaphikweni nakwifestile yefestile yenqwelomoya.
NgeCawa, i-NTSB yaxela ukuba inqwelomoya yayikwimizuzwana embalwa ngaphambi kokuba iwe esibhakabhakeni, enokuthi iphule imithetho yokhuseleko kunye nezikhokelo zenqwelomoya.
Isithethi se-FAA sathi inqwelomoya yacocwa ukuba ibekwi-autopilot ekukhanyeni ukuya kwimeko ye-icing ephakathi. Inkqubo yokuphelisa inqwelomoya yayisebenza kamsinya nje emva kokuba indulukile eNewark.
IHolo yathi ukukhenkceza kwaba ngunobangela kwingozi ye-ATR-1994 ye-twin turboprop plane e-Indiana ngo-72.
UWilliam Voss, umongameli weFlight Safety Foundation, uxelele I’solezwe ngaphambilana ukuba inqwelo-moya eyayibandakanyeke kwingozi yowe-1994 yayizisebenzela ngaphambi kwengozi, nto leyo eyayinokwenza imeko ibe mandundu.
Unobangela wale ngozi yangoLwesine awukachazwa.
UHall uthe inkxalabo yakhe ayikho kwiBombardier, kodwa inesatifikethi senqwelomoya yeemeko ezithile zokubhabha, ezifana nezo zivelisa i-icing.
“Ndiyihlonipha kakhulu inkqubo yokhuseleko lwenqwelomoya yaseKhanada kunye nomenzi wale nqwelo-moya,” utshilo uHolo. “Inkxalabo yam kukungaphumeleli kwenkqubo yoqinisekiso e-United States ngenxa yeengozi ezibandakanya iinqwelomoya eziyilwe ngendlela efanayo, eyayiyi-ATR-72.”
I-Q400 yayingekho kwimarike kude kube ngu-2000 kodwa iHolo yathi ukufana kolwakhiwo kusafanele ukuba kwenziwe uphando kukhuseleko olupheleleyo lweenqwelomoya ezingamawele.
Umkhulumeli we-Bombardier uJohn Arnone uthe ukususela ekubeni i-Q400 yaya kumsebenzi worhwebo ngo-2000 iinqwelomoya ezisetyenziswayo ngoku ziye zangena ngaphezu kwe-1 yezigidi zeeyure zokuhamba kunye ne-1.5 yezigidi zokuthatha kunye nemijikelezo yokuhla.
“Ingozi embi ekufutshane neBuffalo imele abantu bokuqala ababhubhayo kwinqwelomoya yeQ400,” utshilo.
U-Arnone uthe wayengazi naziphi na iziganeko zangaphambili nge-icing.
Uthe akucacanga ukuba kutheni uHolo enze le nkcazo, esongeza, "Ngeliphandle ayitshintshi into ephambili kuthi njengenkampani ngoku," kukuxhasa uphando. I-Bombardier ithumele iqela lezokhuseleko kunye neengcali zobugcisa ukuba zisebenze nebhodi yokhuseleko, watsho.
