The registration is a clue that this DC-9 was delivered first to North Central Airlines (September 16, 1976). With a name change to Republic Airlines in 1979 and merger with Northwest Airlines in 1986, the aircraft was in service until an accident put it out of action. On May 19, 2005, it suffered a failure of one (of two) hydraulic systems. Landing safely at Minneapolis, the crew inadvertently shut down the engine with the good hydraulic pump. Cascading failures of the nose wheel steering, brakes and thrust reversers for lack of hydraulic pressure caused the aircraft to collide with an A319.
