FYI: you need to put it into perspective. How many planes were type-certified between Bulletin 7 or Bulletin 14? The big jump in "word count" happened with the CARs in 1934. The difference between the CARs and FARs was not so much as the CARs used the CAMs which were split into the ACs, etc. once the FARs became the rule. But if you want to count the words : https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgccab.nsf/MainFrame?OpenFrameSet https://www.ecfr.gov/cgi-bin/text-idx?c=ecfr&tpl=/ecfrbrowse/Title14/14tab_02.tpl
