Mawu anayi mu National Transportation Safety Board (NTSB) atolankhani kutulutsa kuti infer kuti wolamulira Teterboro akanatha anachenjeza woyendetsa ndege Piper za helikopita pa Hudson River kuti ndege potsiriza kugunda akutsutsidwa mwamphamvu ndi olamulira ndege. Kutulutsa atolankhani ku NTSB kumanena kuti panthawiyo, woyang'anira Teterboro adauza ndegeyo kuti isinthe ma frequency ake kuti ilankhule ndi oyang'anira Newark Tower, panali ndege zingapo zomwe zidapezeka ndi radar m'derali nthawi yomweyo ndegeyo isanachitike, "kuphatikiza ndi helikopita yangozi." Bungwe la National Air Traffic Controllers Association (NATCA) likulengeza motsindika kuti mawu anayiwa ndi abodza ndipo athandiza kuti anthu aganize mosasamala komanso molakwika kuti wolamulira wa Teterboro akanatha kuteteza ngoziyi.
Chomwecho atolankhani a NTSB amafotokoza momveka bwino kuti helikopita sinawonekere pa radar mpaka 11:52.27, masekondi asanu ndi awiri mutatha kulumikizana ndi ndegeyo kuchokera ku Teterboro kupita ku Newark ku 11: 52.20. Koma ndime yosalembedwa bwino komanso yosocheretsa yokhudza "ndege yangozi" yasiya malingaliro olakwika kuti woyang'anira Teterboro anali ndi udindo wosachenjeza ndegeyo za kuchuluka kwa magalimoto.
Kuphatikiza apo, ndikusokonezanso chimodzimodzi, NTSB idawululira mwachinsinsi kwa akuluakulu a NATCA kumapeto kwa sabata kuti ikudziwa kuti mawu anayi omwe akufunsidwa m'nkhani yake ndi "osocheretsa komanso osayenera." Mkulu wina wamkulu wa NTSB adanena mu imelo kuti mawu akuti "akadakhala omveka bwino" koma kuwongolera "sikuperekedwa."
"Tikukhulupirira kuti NTSB ndiyolakwika kunena kuti panali upangiri wamagalimoto omwe akanaperekedwa kuchokera ku Teterboro Tower kupita ku ndege," atero a Ray Adams, woimira malo a NATCA ku Newark Tower yemwe akuyimira woyang'anira nsanja ya Teterboro pakufufuza kwa ngozi ya NTSB. "Helikoputala sinawonetsedwe pa radar isanasinthe kuchokera ku Teterboro kupita ku Newark Tower. Teterboro analibe mwayi woyimbira kuti traffic. Utumiki wowongolera kayendetsedwe ka ndege umachokera pamayendedwe "odziwika ndi owonedwa". Woyang'anira Teterboro anali asanawonepo kapena kudziwa za helikopita ya ngoziyi pakusamutsa kulumikizana ku Newark.
Komanso, tisaiwale kuti ndegeyo sinalumikizane ndi wailesi ya Newark, monga momwe Teterboro adapempha. Palibe amene ankayankhula naye. Simungathe kuchenjeza woyendetsa ndege yemwe sakulumikizana nanu. Muyenera kufika kwa woyendetsa ndege kaye ndi wolamulira wa Teterboro - monga momwe zafotokozedwera bwino m'nkhani ya atolankhani ya NTSB - anayesa kawiri, koma sizinaphule kanthu.
Anawonjezera Purezidenti wa NATCA a Patrick Forrey: "Ndiloleni ndifotokoze momveka bwino momwe ndingathere: woyang'anira kayendetsedwe ka ndege ku Teterboro adagwira ntchito yake. Tikukhulupirira kuti iyeyo ndi amene wachititsa ngoziyi ndipo palibe chimene akanachita kuti izi zisachitike. Timalemekeza NTSB, ndipo timayamikira kutenga nawo mbali pa kafukufuku wa NTSB. Koma pamenepa, a NTSB yanyalanyaza zomwe tapereka, kupenta malingaliro olakwika a kafotokozedwe ka ntchito ya wolamulira wa Teterboro, ndikulimbikitsa chipwirikiti chodyetsa anthu chomwe chimadzudzula wolamulira wa Teterboro uyu chifukwa chosachitapo kanthu kuti aletse kutsatizana kwa zochitika zomwe zidatsogolera. ku ngozi.
"Tikufunsa mwaulemu kuti a NTSB achitepo kanthu kuti aletse kuthamangira kumeneku kuti aweruze kuti wolamulirayu anali ndi chochita ndi ngoziyi mpaka kafukufuku wa board atamaliza. Kuwongolera pompopompo kutulutsa kolakwika kwa atolankhani kungakhale gawo loyamba loyenera. ”
