Officials said the Beechcraft aircraft crashed in an industrial park about 6 miles from the Fayetteville Regional Airport after an in-flight emergency.
Our crew on the scene says the pilot told air traffic controllers he was having trouble and then the engine quit.
Emergency crews found the aircraft in a wooded area which is part of the industrial park. Authorities said all four people were outside of the aircraft when it was found.
The people on board have been taken to Cape Fear Valley Medical Center.
Officials did not release specifics on their conditions.
The NTSB has been notified and is sending a crew to the scene.
