Mwa anthu 138 omwe anali pabwalo, anthu 25 anatengedwera kuchipatala. Panalibe kuvulala kwakukulu.
Ndege, yomwe inachokera ku Toronto's Lester B. Pearson International Airport, inatulutsa magetsi, kutsegula magetsi ku eyapoti kwa oposa ola limodzi, ndipo inaonongeka kwambiri. Zida zoyendetsa ndegeyo zinasiyanitsidwa ndi ndegeyo pamtunda wa nyerere zambiri, zomwe zinasiya malo ambirimbiri oundana pakati pa antenna ndi mphambano. Mphuno ya mphuno ndi imodzi ya injini inakhalanso yosiyana ndi ndege, ndipo mapiko ake anawonongeka kwambiri.
Anthu onse okwera ndege adatha kutha. Anthu makumi awiri ndi asanu adatengedwera kuchipatala ndikuchiritsidwa chifukwa cha kuvulazidwa kosayenera.
Ofufuza kuchokera ku Transportation Safety Board ku Canada (TSB) anafika pa malowa ndipo analandira Flight Data Recorder ndi Cockpit Voice Recorder. Mabungwewo adati mu deta kuti deta yapadera imatipatsa njira yosakhazikika.
"Ngoziyi ikuwonetsa zina mwa ngozi za kuyandikira-ndi-kutsika zomwe ziri pa Watch Tower TSB." Otsatirawa ndi mndandanda wa mavuto omwe bungwe likufuna kulithetsa ndipo limaphatikizapo "... maulendo a pamsewu, maulendo oyendetsa njanji, kuyenda pamtunda, ndi mchira." Lipotili likuwonetsa kufunikira kwa oyendetsa ndege kuti azionetsetsa kuti akuyendetsa bwino njira zawo ndikuyendetsa zoyendayenda pokhapokha ngati zili zoyenera panthawi yovuta.
Deta ya chiwerengero kuchokera ku lipoti lofalitsidwa ndi Airbus imati "kupitirizabe kusagwirizanitsa ndi chinthu chomwe chimapangitsa kuti pakhale ngozi zowonongeka 40%." Ndipo molingana ndi Airbus, njirayi imayesedwa yokhazikika pamene zinthu zonsezi zikugwirizanitsidwa "musanafike pamtunda wokhazikika" (mwina mamita 500 mu VMC kapena mamita 1000 mu IMC ):
- Ndege ili pa njira yoyendetsa ndege yowonongeka.
- Kungosintha pang'ono pokhapokha pamutu ndi phokoso kumafunika kuti musunge njirayi
- Ndege ikufuna kukonzekera komweko
- Phokoso limakhazikitsidwa nthawi zambiri osati lopanda kanthu, kuti likhalebe liwiro mofulumira potsatira njira yoyenera yopitilira njirayo.
- Mndandanda wazomwe ufikapo ukukwaniritsidwa komanso zofunikanso
- Palibe chiwerengero choyendetsa ndege choposa ndondomeko yomwe ikufotokozedwa mu Table 4, yomwe imatchula magawo otsatirawa kukhala osakhazikika:
- Vapp airspeed yoposa -5 / + 10
- Mawindo ofanana oposa mamita 1,000 pa mphindi
- Khalani ndi maganizo oposa a //- 2 digiri pamwamba kapena pansi
- Mng'oma wa banki wamkulu kuposa madigiri 7
- Kupatuka kwa malo oposa malo oposa 1/4
- Kusiyana kwa Glideslope kupitirira dothi limodzi
Njira yoyenera ya njira yosakhazikika, malinga ndi Airbus, ndi ya woyendetsa ndegeyo kuti apite mozungulira nthawi yomweyo.
"Ngati ndegeyo siimayesetsedwe pa njira yoyendetsera kayendedwe kake, pokhapokha ngati pang'onopang'ono zikhale zowonongeka, zoyenera kuzungulira ziyenera kuyambitsidwa pokhapokha ngati ogwira ntchito akuyesa kuti kusintha kokha ndikofunikira kuti athetseretu zochepa zazing'ono kuti zisayime bwino, chifukwa cha zina, kupita ku zowonongeka kunja. "
Akuluakulu adanena kuti anali oyambirira kwambiri kuti adziwe ngati nyengo ikugwira ntchito, koma nyengoyi imakhala "yocheperako," yomwe ndi woyendetsa ndegeyo-amalankhula kuti ali ndi zovuta zooneka komanso zowoneka kuti apite kuntchito. Ndegeyi inkayenda mozungulira "kwa nthawi ndithu," koma ngakhale kuti kunali matalala, nyengo inali yoyenera kubwerera, malinga ndi lipoti la CBC. Sindikudziwa bwino lomwe chida chimene oyendetsa ndege ankawulukira panthawiyo.
Malingana ndi CBC, aliyense wa oyendetsa ndegewa wagwira ntchito ku Air Canada kwa zaka 15 ndipo aliyense amakhala ndi zambiri pa ndege.
Msewu wa ndege ku Halifax ndege idzawonongedwa mpaka zotsalirazo zitachotsedwa ndipo msewuwu udzayendetsedwa. Kukonzekera kwa ILS kungatenge kwa mwezi umodzi, kupanga msewu womwewo wosagwiritsidwa ntchito mu chida cha meteorological.
TSB idzapitiriza kufufuza.
