No sign of human remains at 9/11 aircraft part site

(CNN) -- No "potential human remains" have been found in the Manhattan location where a 9/11 aircraft part was recently found, New York's chief medical examiner said Wednesday.

The conclusion was made after an inspection at 51 Park Place. That's the location where a piece of one of the planes in the September 11, 2001 terror attack was discovered on Friday.

The office said the 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 found on the wing of a Boeing 767 like the ones that were flown into the World Trade Center.
