Witnesses told police the plane took off to the east, circled around to the south of the airport and was heading north. Holmes says witnesses heard the plane's engine sputter before it crashed.
Holmes says it appears the plane struck a brick wall and then hit a building northwest of the airport.
Earlier, bright, orange flames and clouds of smoke were pouring from the wreckage before Phoenix fire crews arrived on scene and extinguished the flames.
Holmes says the plane is a bundle of charred and blackened metal.
