Has anyone bothered to read AC 43.13-1b Chapter 7 paragraph 7-39 and 7-40 regarding bolt fit and torque for primary connecting elements? I take that to mean this would apply directly to WAF applications. http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/list/AC%2043.13-1B/$FILE/Chapter%2007.pdf Table 7-1 sums it up quite nicely. What part of 40,000 psi don't you understand? I submit the so called "wear mechanism" is due to improperly torqued WAF bolts.
