A small plane owned by an Oklahoma construction company crashed near Chickasha, killing two men, the Oklahoma Highway Patrol said Saturday.

Pilot Rocky Joe Beller, 47, of Goldsby, and Calvin Scott Beller, 50, of Purcell, both died at the scene about 40 miles southwest of Oklahoma City and were the only ones on board the aircraft, according to the OHP, which said the investigation was turned over to the Federal Aviation Administration.

FAA spokesman Roland Herwig said there is an airport in Chickasha, but authorities weren't sure where the Piper PA-28 the men were flying took off or was headed.

Neither the FAA nor the National Transportation Safety Board, which typically investigates fatal plane crashes, immediately responded to messages seeking further comment late Saturday morning. The crash happened about 8:45 p.m. Friday, according to the OHP.

Tom Dodson, of B&H Construction LLC of Norman, said the company owned the plane and Rocky Beller owned the company with his two brothers. Dodson said Calvin Scott Beller was Rocky Beller's cousin.

"He's (Rocky Beller) 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.
