Boeing looked for flaws in its Dreamliner and couldn’t stop finding them
> In 2019, they detected gaps between sections of the Dreamliner’s fuselage that were slightly wider than specified in the FAA-approved designs. The gaps, about the width of a piece of paper, were wider than the manufacturing tolerance of 0.005 of an inch allowed under the approved design.<p>I feel like the article is really grasping at straws here, and I'd be willing to bet the author doesn't even comprehend how small this is. 0.005" is <i>small</i>. For the hardware-challenged: 0.005" is a typical manufacturing tolerance for a standard-spec PCB. Some of the Chinese board-houses that deal in high volume are higher than that[1]. The fact that they even found a gap this size on something the size of an airplane is amazing to me.<p>[1] <a href="https://www.pcbway.com/pcb_prototype/PCB_Manufacturing_tolerances.html" rel="nofollow">https://www.pcbway.com/pcb_prototype/PCB_Manufacturing_toler...</a>
