WASHINGTON - (AP) - The Federal Aviation Administration says it has placed two employees on administrative leave in connection with last week's deadly mid-air collision over New York's Hudson River.

The FAA said Thursday night it has begun disciplinary proceedings against an air-traffic controller who was handling the small plane that collided with a tour helicopter and against a supervisor on duty at the time.

The FAA says the controller was involved in "apparently inappropriate conversations" on the telephone at the time of the accident. The agency says the supervisor was not in the building at the time as required.

However, the FAA says that the employees' actions don't appear to have contributed to the accident itself. Nine people died in the crash.
