Boeing suspects workmanship in Southwest jet flaw

WASHINGTON - Boeing Co believes a tear in the roof of a Southwest Airlines Co 737-300 jetliner in mid-flight this month was related to a manufacturing problem limited to one aircraft.
"I think the initial data that I think we're all seeing is suggesting a possible workmanship issue on an airplane, rather than a design issue across a fleet of airplanes," Chief Executive Jim McNerney told analysts on Wednesday.
Comments by McNerney and Boeing's commercial aircraft chief, Jim Albaugh, were first made publicly by senior management on what might have caused the five-foot tear aboard Southwest Flight 812, which made an emergency landing on April 1 in Yuma, Arizona. No one was hurt.
