WATERFORD TOWNSHIP, Mich. Federal investigators say they haven't found any sign of equipment problems on a small plane that crashed shortly after takeoff from a suburban Detroit airport, killing all four people aboard.
The crash happened Friday at Oakland County International Airport in Waterford Township.
It killed 19-year-old pilot Troy Brothers, his 53-year-old mother Sandra Haley, 58-year-old stepfather James Haley, and 34-year-old brother-in-law Jamie Jose.
Brothers radioed a controller that the plane was "a little over weight" and he was turning around shortly before the crash.
The Macomb Daily of Mount Clemens says a preliminary National Transportation Safety Board report found no signs of equipment problems with the aircraft.
The agency has said it plans to examine video of the crash taken by a security camera.
