That's according to a preliminary report Monday by a National Transportation Safety Board investigator.
NTSB spokesman Nicholas Worrell says the four-seat Rockwell Commander 114 crashed and burned about 6 p.m. Sunday on Needles Highway -- minutes after takeoff and less than 5 miles southwest of Laughlin-Bullhead International Airport.
A Clark County fire official says one person died in the crash. He was identified as 72-year-old James Walker of Avondale, Arizona. Three others were hospitalized and later passed away. The Coroner identified them as 58-year-old Diana Soto of Goodyear and 64-year-old Evelina Walker of Avondale.
A Federal Aviation Administration spokesman says the aircraft had been bound for Phoenix Goodyear Airport.
