The number chart for reporting wheel defects has been updated. The orientation layout has been changed to permit easier recording of flat spot measurements if the sheet has been folded. I’ve also added the phone number for CNOC mechanical for defect reporting. <br /><br />Also see the attached PDF of Title 49, Part 229, Subpart C, Section 229.75 for additional information. A link to the original is below.<br /><br />http://www.gpo.gov/fdsys/granule/CFR-2011-title49-vol4/CFR-2011-title49-vol4-sec229-75&nbsp; <br />
