Two Ohio residents were killed after a six-seat airplane crashed Thursday evening in White Plains.

The plane was flying from JFK Airport, headed for Cuyahoga County Airport in Ohio, when the pilot, Boruch Taub, reported engine issues around 5:30 p.m. It crashed shortly after that, said Westchester County Executive George Latimer during a press conference Friday morning. Taub and passenger Ben Chafetz died in the crash.

The plane was somewhere over the Long Island Sound when Taub reported low oil pressure. He alerted the Federal Aviation Administration as he attempted to make an emergency landing.

“As the plane was traveling, it was losing altitude because of … whatever is ultimately determined to be the reason, and the pilot recognized that he had only a handful of minutes to try to bring the plane to a safe landing,” Latimer said in a press conference. “He was unable to do that. The plane was lost about two miles from the runway at Westchester County Airport.”

The preliminary report from the Federal Aviation Administration said that the single-engine Beechcraft A36 Bonanza plane crashed “under unknown circumstances in Peninsula Rye Lake.” But investigators ultimately found the plane on land and trees north of the lake, Latimer said.

“It was a very difficult search to try to find the remains of the plane and of those individuals that were in the plane,” Latimer said, noting the inclement weather at the time of the crash and the surrounding dark, wooded area.

The FAA and the National Transportation Safety Board are investigating the crash. Officials at the press conference were not able to say why the oil pressure may have been low early on in the flight.
