WATERFORD TOWNSHIP, Mich. (AP) - A federal investigation found no major mechanical problems in a plane crash that killed the 19-year-old Michigan pilot and three family members.
A recently updated National Transportation Safety Board report says "there was no evidence of pre-impact airframe, power plant or propeller malfunction or failure" in the June crash at Oakland County International Airport.
The single-engine Cessna 172 crashed shortly after takeoff. Killed were the pilot, Troy Brothers; his mother, Sandra Haley; his stepfather, James Haley; and his cousin, Jamie Jose.
The Detroit News reports Monday that Brothers earned his private pilot's license a month earlier.
According to the NTSB, Brothers reported to the control tower "that he was 'a little overweight' and would need to return and land."
