Between 1970 and December 2016 there have been 110 serious incidents involving the Tu-154 , and 69 hull losses , 30 of which did not involve fatalities . Of the fatal incidents , five resulted from terrorist or military terrorist action ( two other wartime losses were non fatal ) , several from poor runway conditions in winter ( including one in which the airplane struck snow plows on the runway ) , cargo overloading in the lapse of post-Soviet federal safety standards , and mid-air collisions due to faulty air traffic control . Other incidents resulted from mechanical problems ( two cases prior to 2001 ) , running out of fuel on unscheduled routes , pilot errors ( including inadequate flight training for new crews ) , and cargo fires ; several accidents remain unexplained
