Pictures from Chopper 11 showed the ultralight aircraft down behind a home on Pierce Lane in the Erwin area.
Officials said the pilot - the only person on board - was killed.
He's been identified as 71-year-old Marshall Thomas Watkins.
The Harnett County Sheriff's Office said witnesses reported that the aircraft was taking off from a grassy private airstrip located next to Pierce Lane. It appeared to the witnesses that a gust of wind pushed the aircraft toward a group of trees near the runway, the aircraft made a sharp turn away from the trees and went down.
