The ranch property where the plane crashed is surrounded by homes so it could have been even worse.
Offcials said that three people, including the pilot were killed. Early in the investigation, fire officials had reported four people were dead.
Investigators said the plane disintegrated on impact and exploded into flames and killed three horses on the property. Several injured horses were taken to a veterinarian.
"The plane is completely destroyed in pieces and the fire that ensued after the impact is in a tightly contained area--probably within a less than 30-foot diameter inside of a corral area behind some horse barns," said Capt. Bob Goldman of the Los Angeles County Fire Department.
Officials said the plane was going from Van Nuys to Parker, Ariz.
Goldman said that the plane looked to be made of very lightweight material, mostly fiberglass, and the landing gear was very small.
"It was close enough to my house that you can actually almost feel the airwave puff at the house," resident Dallas Hodge.
Hodge lived nearby. He said when the plane was going down, he thought about getting out of his house because he was scared the plane might crash into it.
"By the time I got to the front door, the explosion hit, shook my house," said Hodge.
The cause of the crash is still under investigation.
