NTSB: Loose rivets found in plane with hole - Updated Today
WASHINGTON (AP) -- Investigators trying to determine why the roof of a Southwest Airlines jet cracked open in flight have issued preliminary findings suggesting there may have been flaws in the riveting work when Boeing built the plane 15 years ago.
The National Transportation Safety Board said Monday that some of the rivets used to bind the Boeing 737's aluminum panels together were sunk in holes larger than the rivet shafts. The holes weren't lined up correctly and were misshapen, not round, the board said.
