EAST HARTFORD, Conn. (AP) The National Transportation Safety Board says the FBI is taking over the investigation into a fatal plane crash in Connecticut because of indications that it could have been a criminal act.

The NTSB said Wednesday that its initial investigation indicates Tuesday's crash in East Hartford was intentional. An agency spokesman, Terry Williams, said he couldn't elaborate on the basis of that finding.

One person aboard the plane was killed and another survived when the Piper PA-34 Seneca crashed Tuesday afternoon as they were trying to land at Brainard Airport in Hartford. It crashed near the headquarters of Pratt Whitney, which makes military and commercial jet engines.

The mayor said Wednesday the survivor told authorities that the crash wasn't an accident, but she cautioned the information had not been confirmed.

Police say there were two sets of controls aboard a small plane that crashed in Connecticut with a flight instructor and student on board, killing one of them.
