Whistleblower speaks out on quality issues at Boeing supplier: "It was just a matter of time before something bad happened"

A former quality manager who blew the whistle on Spirit AeroSystems, a troubled Boeing supplier that builds the bulk of the 737 Max, says he was pressured to downplay problems he found while inspecting the plane's fuselages. 

For about a decade, Santiago Paredes worked at the end of the production line at the Spirit AeroSystems factory in Wichita, Kansas, doing final inspections on 737 fuselages before they were shipped to Boeing.

"If quality mattered, I would still be at Spirit," said Paredes, who told CBS News in an interview he was finding hundreds of defects every day. "It was very rare for us to look at a job and not find any defects."
