Abantu abalishumi elinanye basweleke phezolo eOahu, xa inqwelomoya yeBeech 65-A90 yantlitheka kamsinya nje emva kokusuka eDillingham Airfield on kuNxweme oluMantla lwaseOahu, eHawaii. Ijongwa njengeyona ntlekele inkulu yorhwebo ngenqwelomoya kwi-US State yaseHawaii kule minyaka ingamashumi amabini idlulileyo.
Kuyabonakala ukuba le nqwelo-moya inembali yeengxaki. Ngo-2016 iBhodi yeSizwe yoKhuseleko lwezoThutho (NTSB) yathumela le ngxelo ilandelayo malunga nesiganeko xa le nqwelo-moya yayisetyenziswa eCalifornia.
Ngomhla we-23 kaJulayi, i-2016, malunga ne-1900 ixesha lokukhanya kwe-Pacific, i-Beech 65-A90, i-N256TA, igcine umonakalo omkhulu emva kokulahlekelwa kolawulo ngelixa ikhuphuka kufuphi ne-Byron Airport (C83) e-Byron, eCalifornia. Umqhubi wezorhwebo kunye nabakhweli be-14 abazange benzakale. Inqwelomoya yabhaliswa kwi-N80896 LLC, kwaye iqhutywa yi-Bay Area Skydiving phantsi kwamalungiselelo e-14 Code of Federal Regulations Part 91. Iimeko zemeteorological ezibonakalayo zazikhona kwaye akukho sicwangciso sokubhabha esifakwe kwinqwelomoya yokuntywila esibhakabhakeni. Inqwelomoya yasekhaya yemka i-C83 malunga ne-1851.
Ngokomqhubi wenqwelomoya, njengoko inqwelomoya yayisondela kwindawo yokutsiba ecwangcisiweyo kunye nokuphakama, malunga ne-12,500 ft, inqanaba lolwandle elithetha ukuba, waqala ukujika ngasekhohlo ukuya kumgca we-drop zone. Uye wathi isantya senqwelomoya sacotha kancinci emva koko “ngequbuliso inqwelomoya yazinza, yaqengqeleka yaya ngasekhohlo, yaza yaqala ukujikeleza impumlo ukuya ezantsi.” Uye wathi inqwelomoya "yenze imibhobho emibini ezantsi." Omnye wabatsiba-tsiba, owayehleli kwisitulo somqhubi wenqwelo-moya, weva “isandi esikhulu” ebudeni bolandelelwano lokuchacha waza wathi “umqhubi wenqwelo-moya akazange ayibambezele imilenze ngexesha lokuchacha, nto leyo eyabangela ukuba inqwelo-moya ibe nesantya esiphezulu.” I-jumper yathi ngexesha lokuchacha weva i-g-force esiswini sakhe. Umqhubi wenqwelomoya wathi ubuyisele okwethutyana inqwelomoya kwisimo sengqondo somgangatho wamaphiko kwimizuzwana embalwa kwaye waqaphela ukuba inqwelomoya yayimalunga ne-90 ° ukusuka kwisihloko esicwangcisiweyo, kwaye icotha kwisantya somoya.
Emva koko, umqhubi wenqwelo-moya wathi kukho “umothuko” kwiindlela zokulawula yaye “ngaxeshanye inqwelo-moya yaphuka ngokukhawuleza ngasekhohlo,” yema okwesibini, yaza yaqalisa ukujikeleza isiya ezantsi. Umqhubi wenqwelo-moya uxelele abo bantywila esibhakabhakeni ukuba batsibe bephuma kwinqwelo-moya. Iiparachutists zathobela, kwaye zonke zaphuma ngempumelelo kwinqwelomoya ngexesha lesi siganeko sesibini. Umqhubi waqala inkqubo yokubuyisela i-spin ngaphandle kwesiphumo esicacileyo malunga nokujikeleza kwe-9 kwaye wathi ireyithi yokuqengqeleka yayikhawuleza kakhulu kunomcimbi wokuqala we-spin. Emva koko watsalela zombini izithinteli zokulawula iintsiba kwindawo yontsiba kwaye wakwazi ukuphuma kwi-spin. Wayibuyisela kwinqwelo-moya kwiphiko nesantya sokuhamba, kodwa kungekudala emva koko, inqwelo-moya “yaphuka ngasekhohlo” yaza yema okwesithathu. Umqhubi wenqwelo-moya wayibuyisela kwakhona inqwelo-moya ngokuyithoba isantya somoya nangokunyusa isantya.
Umqhubi wenqwelomoya ujike wabuyela ngakwisikhululo seenqwelomoya kwaye njengoko inqwelomoya ibiphethe ngendlela engaqhelekanga, wahlengahlengisa isisingisi sokuphakama kwempumlo ukuze simncede agcine ukubhabha okuthe tye kunye nenqanaba. Watsho ukuba ukusetwa kwempumlo epheleleyo kwasetyenziswa kwindlela yokufikelela. Ukongeza, umqhubi wenqwelomoya uqhube amaqhina angama-15 ngokukhawuleza kunokuba kuyimfuneko, ukuze ahlawule umba wolawulo lokuncipha okuphawulweyo ekusebenzeni kwe-elevator.
Umqhubi wenqwelo-moya uchaze ukumisa njengempumlo esezantsi xa kuthelekiswa nendawo eqhelekileyo. Emva kokufika kwi-C83, ingqina labona ukuba i-horizontal stabilizer ye-airplane, kunye ne-elevator eqhotyoshelweyo, yayilahlekile. Iindawo ezahluliweyo zenqwelomoya zaye zabekwa emva koko kwibala elikwiimayile ezimbalwa emazantsi esikhululo seenqwelomoya.
Umqhubi wenqwelomoya uxele ukuba akukho nto ingaqhelekanga kwinqwelomoya kwiinqwelomoya zangaphambili ngaloo mini, okanye ngexesha lokuhlolwa kwakhe kwangaphambili kwenqwelomoya yengozi. Wachaza ukuba imozulu yayipholile kwaye kukho i-chop elula. Ngaphezu koko, akazange achaze imiba yenjini ngexesha lokuhamba.
Ukuhlolwa kwe-postaccident yenqwelomoya kubonise ukuba izikhumba zephiko eziphezulu kunye nezisezantsi zazingenakulinganiswa. Ukunyuswa kwe-injini kunye neendawo zokuncamathela ezizinzisiweyo ezisekhohlo ezithe tyaba zavavanywa ngoxinzelelo, kodwa akukho namnye owabonwayo. Akukho zimpawu zokuphaphazela zabonwa kwi-horizontal stabilizer ekhohlo.
I-stabilizer echanekileyo ethe tye, kunye ne-elevator eqhotyoshelweyo, eyahlula kwinqwelo-moya, ihlolwe. I-elevator efanelekileyo kunye ne-elevator trim tab yahlala iqhotyoshelwe kwiindawo zabo zokunamathisela. Ukuqhekeka kwabonwa kwinqanaba eliphambili kunye ne-trailing edge spars kwi-horizontal stabilizer ekunene. Kwakukho imibimbi kumphezulu wolusu. Isibiyeli sokuncamatheliswa esidityanise isizinzisi esithe tye kwinqwelomoya, nakwesinye isizinzisi esithe tyaba, sibonise indawo ezaphukileyo kwicala lasekunene apho isizinzisi esithe tye sasekunene sincanyathiselwe.
Izahlulo zesizinzisi esithe tye sasekunene, ilifti, kunye nesibiyeli sokuncamathelisa zathunyelwa kwiBhodi yeSizwe yoKhuseleko lwezoThutho lweMpahla yeLabhoratri ukuze ihlolwe ngakumbi. Ukuhlolwa kwe-optical optical eyandisiweyo yeendawo eziqhekekileyo zibonakalise iimpawu ezihambelana nokuhlukana koxinzelelo. Akukho nto ibonisa ukudinwa okanye ukubola kwabonwa. I-Deformation kunye neepateni zokwaphuka kwiindawo ezifanelekileyo zokuzinzisa ezithe tye zazibonisa incam yokuzinzisa egobela phezulu kwaye i-spar esezantsi nayo yayikrazulwa phezulu kweewebhu.
Incwadi yesikhokelo yokubhabha yenqwelomoya ithi: “Ngoko nangoko hambisa ikholamu yolawulo iphelele phambili, faka iphini elipheleleyo elijongene necala apho ijikelezisa khona, kwaye unciphise amandla kuzo zombini iinjini ukuba zingasebenzi. Ezi ntshukumo zintathu kufuneka zenziwe ngokusondeleyo ngaxeshanye kangangoko kunokwenzeka, emva koko uqhubeke ubambe le ndawo yolawulo de ujikelezo luyeke kwaye emva koko lunciphise lonke ulawulo kwaye luphumeze ukutsalwa okugudileyo. UAilerons kufuneka angathathi hlangothi ngexesha lokuchacha. ”
Ubunzima benqwelomoya kunye nebhalansi yayo ibalwe kwinqwelomoya yengozi. Iziko lomxhuzulane (CG) liqikelelwa ukuba limalunga neeyunithi ezi-6-7 emva komda. Ngenxa yombindi womxhuzulane (cg) ungaphaya komda, obona bunzima buvumelekileyo bubonke khange bukwazi kuqinisekiswa ngexesha lengozi. Ngokutsho kweFAA Pilot Handbook of Aeronautical Knowledge ithi, “njengoko iCG ihambela ngasemva, kubakho imeko engazinzanga, nto leyo eyenza inqwelo-moya ingakwazi ukuzihambela kakuhle emva kokuba iqhubekile okanye isiphithiphithi.”
