ROSEVILLE -- A single-engine plane that appeared to be performing an aerobatic stunt lost control and crashed into a home Sunday, killing at least two people and sparking a fire that gutted the house.

The 11:24 a.m. crash left a gaping, smoldering hole in the two-story house it directly hit and set fire to an adjacent house, damaging the garage and attic, said Roseville Fire Marshall Dennis Mathisen. One body was visible in the wreckage.

Placer County Deputy Coroner T. Sinclair confirmed that two people were on the plane, and a teenage boy who lived in the house was unaccounted for. Neighbors said the boy's family was out of town for the weekend, and it was unclear if he was home at the time.

Sinclair said no one could have survived the crash, but he was unable to confirm any deaths Sunday because the Federal Aviation Administration wasn't allowing officials into the wreckage to retrieve bodies until Monday.

The plane -- which the FAA identified as a 1996 Glasair II -- appeared to be doing an aerobatic maneuver when it crashed, said Roseville Police spokeswoman Dee Dee Gunther.

"The pilot appeared to be coming down low for some kind of maneuver that brought him to within 500 feet of the rooftops," she said. "And then he appeared to lose control and crashed into one of the houses."

Rick Wurster, who lives about a half-mile from the crash, saw the plane attempting to make a figure eight.

"He couldn't pull up because he didn't have enough altitude," Wurster said. "I saw him do two spins and then go over the tree line. A second later, I heard two booms."

Peter Hugenroth, who lives nearby, was in his house when the plane went down in the quiet residential neighborhood of Roseville, about 16 miles northeast of Sacramento.

"There was a huge boom and instant fire," he said. "By the time I got to the crash there was no sign of the plane. Everything was engulfed in flames."

An FAA representative is on the scene investigating the crash, said Bruce Nelson, an operations officer for the agency in Los Angeles.

The pilot was not communicating with air traffic controllers at the time of the crash, Nelson said. The plane had taken off from Lincoln Regional Airport, about 10 miles north of the crash site.

Twelve-year-old Garrett Osgood said he was sleeping in his bedroom when he was awoken by the plane's impact next door. Osgood, whose family was out at the time, was able to escape with his two dogs before parts of his house also caught fire.

"I ran out of the house, and there was a whole bunch of debris falling from the sky. A piece fell right in front of me, and it was in flames," Osgood said. "My whole room's melted. My pet snake's probably dead."
