At 22:04 mountain time, a Piper PA-44-180T collided with a Cessna 182Q while the Piper was making a go-around and the Cessna was taxiing. No one was injured. The pilot of the Seminole apparently was making a go-around after abandoning a landing approach to runway 17L. The airplane drifted left of the runway and collided with the Cessna, which was taxiing north on taxiway Bravo. The Piper pilot then landed the airplane on the grass median between the runway and taxiway.
