According to Reuters Aerospace supplier Spirit AeroSystems (SPR.N) manufactured and initially installed the fuselage part on a brand-new Boeing 737 Max 9 jet that suffered a blowout on Friday.

Because of a complex, two-tier installation process, investigators are expected to examine whether any flaws occurred at Spirit’s giant fuselage plant in Wichita, Kansas, or at the Boeing factory outside Seattle, the sources said.

SPR closed at $31.73 on Friday Jan 5^th,shares on Monday may be under pressure as investors look for further clarity.
