A small plane crashed into a yard Sunday morning, killing four people aboard and embedding its engine into a house, authorities said.

No injuries to people on the ground were reported. The victims' names were not immediately released.

The control tower at Charlotte-Douglas International Airport notified fire officials of a crash at 11:30 a.m., fire Capt. Rob Brisley said. It wasn't clear whether the single-engine Cessna, which crashed about three miles from the airport, was taking off or landing.

A second single-story brick home in the neighborhood also suffered structural damage, while the rest of the damage to a few homes was "very minor," Brisley said.

At least a half-dozen people were temporarily displaced, he said.

The crash initially cut power to about 40 homes but most had power restored by late afternoon, Brisley said

The Federal Aviation Administration and National Transportation Safety Board were investigating.
