FORT LAUDERDALE, Fla. (AP) - An American who returned from Cuba decades after hijacking a jetliner to the communist island is set to plead guilty to a kidnapping charge in South Florida federal court.
    
A change of plea hearing was set Thursday for 57-year-old William Potts, who said he returned last year from Cuba to finally resolve the 30-year-old U.S. case.
    
The kidnapping count replaces a previous charge of air piracy, which carried a mandatory prison sentence of at least 20 years. Potts is seeking credit for 13 years he served in a Cuban prison. He still faces a maximum life sentence.
    
The FBI says Potts claimed he had explosives when he hijacked a New York-to-Miami flight to Havana in 1984. He described himself then as a black militant calling himself "Lt. Spartacus."
