New York ( CNN ) -- No `` potential human remains '' have been found in the Manhattan location where a 9/11 aircraft part was recently discovered , New York 's chief medical examiner said Wednesday . The announcement followed an inspection at 51 Park Place , where a piece of one of the planes in the September 11 , 2001 , terror attack was found Friday . It was removed Wednesday . The piece was wedged in an 18-inch space behind the building , the site of the controversial Islamic community center known by its critics as the `` ground zero mosque . '' The office said soil-sifting operations have been completed at the site , where the 5-foot-long , 4-foot-wide , and 17-inch-deep part was found . A Boeing Company technician confirmed that the piece is a support structure from a trailing edge flap on the wing of a Boeing 767 like the ones that were flown into the World Trade Center . Police officers hoisted the 255-pound piece out of the location with a pulley and loaded it onto a truck bound for a police property facility in Brooklyn . One police official described the mood at the scene as `` eerie . '' Some of the personnel there responded to the attack . `` It 's a piece of history and we tried to preserve it as best we could , '' said Police Deputy Chief William Aubry . `` It brought back a lot of memories . ''
A Boeing maintenance technician confirms the piece is from a Boeing employee . It was found behind the building of a controversial Muslim community center . The piece was taken to a storage facility in Chicago .
