Korean Air Lines said yesterday that 55 Americans were confirmed lost in its final count of the 269 passengers and crew who died when their airliner plummeted into the Sea of Japan.

The Associated Press listed 61 U.S. citizens who died in the crash. The extra six apparently were listed differently because of their dual citizenship: Korean Air Lines counted them among other nationalities and the Associated Press listed them among Americans.

A Korean Air Lines spokesman said all 269 passengers and crew members have been identified and their citizenship determined. But the process has been difficult, the spokesman said, because the flight manifest offers no information on each passenger other than a name, sometimes misspelled, and a telephone number.

From the phone numbers, the airline must try to find someone who can give the details of the passengers' identities.

In addition to the 52 Americans listed in yesterday's editions of The Washington Post, those added to the list, including those with apparently dual citizenship, are:

Joseph Chan, of Samar, Philippines; Sarah Draughn, 20, Medford, Mass.; Richard Ellgen, New York; Bill Hong, 41, Greenville, S.C.; Graham Park, 2, Buffalo, N.Y.; Sarah Park, 4, Buffalo, N.Y.; Anna Song, 63, Yonkers, N.Y.; Chung Soo Yoo, 45, Pittsburgh; and Sirena Wuduun, 20, New York.

The overall total given by the airline is 55 Americans, 81 Koreans, 36 Chinese, 28 Japanese, 16 Filipinos, 10 Canadians, six Thais, four Australians, and one each from Sweden, India, Malaysia and Vietnam. The jet also carried 29 Korean crew members. No bodies have been found.
