When I was working at Boeing, Boeing Wichita made the horizontal stabilizer for the 737, but that was 15 years ago. Also, while I was there, a design of mine for a piece of jettisonable hardware on a B-52 was mis-installed (they left out a hinge bolt), and at first the test failure was attributed to bad design, then failure research showed the bolt was never installed.
