The Federal Aviation Administration is preparing to begin its airworthiness certification inspection of a World War II bomber.

Volunteers have been putting the finishing touches on the B-29 Superfortress known as "Doc."

The nonprofit group working to restore the plane says on its website that the next step is for the FAA to perform a physical inspection. The aircraft then will be inspected during engine runs.

The group will need an FAA airworthiness certificate before they can attempt a first flight of the B-29.

The Wichita-built plane was finished too late to fly bombing missions during World War II, though it eventually served as a radar trainer during the Korean War.
