SAN JOSE, Calif. (AP) _ The Bradley Fighting Vehicle, a heavily armed personnel carrier used widely in the United States and Europe, flooded with nearly 6,000 pounds of water and almost sank during a videotaped test last April, a newspaper reported Thursday.

The test of the Bradley's amphibious capabilities by its builder, FMC Corp. in San Jose, was part of a series of tests supervised by Henry Boisvert, the San Jose Mercury News said.

Boisvert is a former FMC test analyst who sued the company last month, contending FMC covered up serious defects in the Bradley. The Mercury News said it obtained a copy of the tape from Boisvert's attorney, Phillip Svalya, on Wednesday.

FMC spokesman William Highlander said he had not seen the tape and was not aware whether FMC management had copies of it, but he said he was told that information on the tape was ''inaccurate.''

He said the pending lawsuit prevented him from telling exactly what was inaccurate on the tape.

The taped test, which Boisvert said occurred on April 23 near San Jose International Airport, is not the first time the 25-ton Bradley has come under public fire.

On Sunday, the Mercury News reported that Boisvert had warned FMC management about a Feb. 18 test in which a Bradley flooded and its bilge pumps were inadequate to remove the water.

Local television stations recently have aired tapes of the Bradley sinking during Army tests several years ago. At least one Bradley has sunk in Germany, according to an FMC memorandum.

The U.S. Department of Justice is investigating Boisvert's lawsuit and has interviewed Boisvert and other FMC employees about his allegations.

FMC builds the Bradley under a $12 billion contract with the Army.
