NEWPORT, R.I. (AP) _ The Coast Guard said today it has abandoned hope that anyone survived among the 217 people on board EgyptAir Flight 990.

``We believe at this point it is in everyone's best interest to no longer expect we will find survivors,'' said Coast Guard Rear Adm. Richard M. Larrabee.

Larrabee said searchers found a ``significant piece'' of the aircraft, large enough to require a crane, while scouring a 9,000-square-mile area over a 35-hour period.

Searchers located a signal, most likely from one of the so-called black boxes on the jetliner.

Only one body had been found, but searchers were finding ``evidence of further human remains,'' Larrabee said.

``The average life expectancy in water temperatures of 58 degrees in five to six hours,'' Larrabee said. ``We have far exceeded that.''
