WASHINGTON (AP) _ Federal investigators are looking into allegations that Teamsters president Ron Carey has ties to organized crime figures and appointed some of them to high union posts, The Washington Times reported in Monday editions.

The newspaper, citing unidentified law enforcement officials and other sources, said authorities are investigating allegations that Carey maintained relations with reputed members of the Luchese crime family in New York.

One federal investigator familiar with the matter described the inquiries as ''preliminary at best,'' the newspaper said.

Teamsters spokesman Matt Witt told the newspaper that the union was unaware of any inquiries. Witt said such assertions about Carey could come from some union members and company management officials ''uncomfortable with his reform efforts.''

Carey took over the 1.5 million member union last year, pledging to rid the organization of mob corruption. He was the first Teamsters leader elected directly by the union membership.

Sources told the Times that the allegations have attracted the attention of the government's Independent Review Board, a three-member oversight panel formed by the Justice Department in 1989 as part of a consent decree with the troubled union over racketeering charges.

The newspaper, quoting sources, said the allegations contend that Carey:

-Had dealings with Alphonse ''Little Al'' D'Arco, former acting boss of the Luchese family.

-Testified on behalf of reputed Luchese family member John Conti during a 1975 extortion trial.

-Appointed William Genoese as a key union leader. Genoese has been criticized by IRB member Frederick B. Lacey as being ''unbelievably oblivious'' to corruption.

-Appointed William Cardinale to the board of New York Local 804. Authorities have said Cardinale is an associate of the former boss of the Colombo crime family.
