WHITE PLAINS - A federal report reveals most accusations of air traffic controller violations at Westchester County Airport were untrue or unproven.

Air traffic controllers at the airport had been accused of using their personal cellphones and sleeping on the job between 2011 and 2012. The report, obtained by News 12, showed most of the allegations were either false or unproven. However, the investigation did uncover two instances where air traffic controllers were texting or using their cellphone while on duty.

The investigation also found most of the cellphone use reported was inside a temporary break room in the tower, thanks to a broken elevator.

Calls seeking comment from the union representing air traffic controllers were not returned.The office of special counsel says it is working with the FAA to determine disciplinary action for the controllers who were found violating the rules.
