Accidents & Serious Incidents involving DC91

  • DC91 / B722, Detroit MI USA, 1990 (On 3 December 1990 a Douglas DC9-10 flight crew taxiing for departure at Detroit in thick fog got lost and ended up stopped to one side of an active runway where, shortly after reporting their position, their aircraft was hit by a departing Boeing 727-200 and destroyed by the impact and subsequent fire. The Investigation concluded that the DC9 crew had failed to communicate positional uncertainty quickly enough but that their difficulties had been compounded by deficiencies in both the standard of air traffic service and airport surface markings, signage and lighting undetected by safety regulator oversight.)
  • DC91, vicinity Kansas City MO USA, 1999 (On March 4, 1999, a DC91 operated by USA Jet Airlines, at night and on final approach to land at Kansas City International Airport encountered a flock of large birds. The crew managed to regain sufficient thrust to continue the approach and land without further incident.)
