This AC from 2009 lays out some regulations on it for part 21 regulations

  terms. The new rule uses plain language.


It looks like they also made a lot of changes to the medical code in 1996 that covers it as well.


  
  Where appropriate, changes are made to eliminate gender-specific pronouns, to replace ‘‘applicant’’ with ‘‘person,’’ to use current
  position titles and addresses, to correct spelling and improve syntax,
  and to adjust section and paragraph references.
