The failure of a jackscrew on a Yakovlev Yak-42 airliner due to design flaws resulted in the crash of Aeroflot Flight 8641 in 1982 . The failure of a jackscrew on a McDonnell Douglas MD-80 , resulting from a lack of grease , brought down Alaska Airlines Flight 261 in 2000 . The destruction of a jackscrew on a Boeing 747-400F , brought down National Airlines Flight 102 in 2013 .
