At 18:28 Pacific time, a Piper PA-28-140 and a Piper PA-46-310P collided on runway 16R. No one was injured. The Malibu pilot was cleared to land and advised there would be traffic departing before his arrival. The controller then cleared the Cherokee to taxi into position and hold at intersection 13F and advised the pilot of a Malibu three and a half miles out. The Malibu pilot reported being on final and was again cleared to land. The Cherokee was still holding in position when the Malibu came up from behind.
