Citizens reported hearing a crash about 9:30 p.m. Friday, and deputies later confirmed the Piper PA-28 had crashed about five miles south of Chickasha, FAA spokesman Roland Herwig said. Chickasha is about 40 miles southwest of Oklahoma City.
Herwig said at least one person died in the crash, but authorities weren't sure how many people were on board.
Tom Dodson, of B&H Construction LLC in Norman, said the company owned the plane and two people were on board. He identified them as company co-owner Rocky Beller and his cousin, Calvin Scott Beller.
Beller, 47, owned B&H Construction with his two brothers and was a pilot, Dodson said.
"He's flown quite a bit of hours, I think, but only finished getting his license over the summer," he said. "Studied a whole lot with it."
Dodson wasn't sure where Beller may have been flying.
Herwig said there is an airport in Chickasha, but authorities weren't sure where the plane took off from or was headed.
