지난 7월 장병 5명의 목숨을 앗아간 해병대 상륙기동헬기 ‘마린온’ 추락사고가 회전 날개와 동체를 연결하는 로터마스트(회전날개축) 불량 때문인 것으로 드러났다.
The crash of the Marine Corps' landing-driven helicopter "Marine On" in July, which claimed the lives of five soldiers, was found to have been caused by a faulty rotor mast linking the rotated wings to the fuselage.
