飛箭航空1285號班機是一班國際包機,由一架麥道DC-8型客機執行。此航班載著256名軍人及機員從埃及開羅國際機場起飛前往肯塔基州的坎貝爾堡,中停德國科隆加拿大紐芬蘭島1985年12月12日當天早上,1285號班機從加拿大起飛前往坎貝爾堡不久即失速墜毀,機上所有人罹難。[1]

负责对此次空难进行调查的加拿大航空安全局(CASB)认为,事故很有可能是因为机翼前缘产生了大气结冰 ,从而使飞机出现出乎意料的阻力升高而升力降低的情况[2] 而一份少数派报告则指出事故可能是由于坠毁前机舱内不明原因的爆炸而导致的。[3]

目录

[编辑] 飛機資料

機身編號N950JW的DC-8客機是飛箭航空用以接載美軍的一架包機,機上大部份是屬美國陸軍的第101運輸中隊。他們於西奈半島逗留了六個月,其間與其他國家軍隊及考察團共同維持和平任務後,返回位於肯塔基的坎貝爾堡美軍基地。1285號班機於當天早上降落於Gander國際機場作燃料補給後,隨即準備返回肯塔基。

[编辑] 墜機過程

這架DC-8型客機,於當地時間6時45分於紐芬蘭島機場的13跑道轉向22跑道準備起飛。[4] 在飛機滑行了51秒,空速達167節,接近滑行道「A」時,飛機離地後卻有一種難以飛高的感覺。到了飛機增加空速至172節,這架DC-8客機卻正在下降。飛機越過加拿大橫貫公路時,飛行高度極低,最後飛機墜落於離跑道3千尺以外的Gander湖邊的低地,飛機立即爆炸起火,火勢持續了4小時。[1]

[编辑] 事故調查及報告

事件由加拿大航空安全局(CASB)負責調查, and, under the signature of five of nine board members, issued the following Probable Cause statement in its final report:[1][2]

The Canadian Aviation Safety Board was unable to determine the exact sequence of events which led to this accident. The Board believes, however, that the weight of evidence supports the conclusion that, shortly after lift-off, the aircraft experienced an increase in drag and reduction in lift which resulted in a stall at low altitude from which recovery was not possible. The most probable cause of the stall was determined to be ice contamination on the leading edge and upper surface of the wing. Other possible factors such as a loss of thrust from the number four engine and inappropriate take-off reference speeds may have compounded the effects of the contamination.

Four members of the CASB dissented, issuing a minority opinion which concluded:[3]

An in-flight fire that may have resulted from detonations of undetermined origin brought about catastrophic system failures.
