Two people were aboard the Glasair II single-engine homemade plane, said Allen Kenitzer, a spokesman for the Federal Aviation Administration, although the identities had not been released Monday morning.
Residents in the city northeast of Sacramento said the plane had been performing stunts Sunday afternoon when it crashed into a house and burst into flames.
The family that lives in the house was away on vacation, and no one else was injured in the crash, which shook the neighborhood, the Sacramento Bee reported Monday.
The two bodies were left in the remains of the aircraft overnight to allow crews to stabilize the badly damaged home before extricating the bodies and wreckage, Roseville Fire Marshal Dennis Mathisen said.
Neighbor Mitch Prather said he felt badly about crash and loss of life, but said he was also angry anybody would endanger homes and lives by performing stunts so close to a neighborhood.
"You feel bad at first, but then you get furious," he said.
