Slack and Sanger Among First Texas lawyers to Receive New Aviation Law Certification

Austin, Texas – Slack Davis Sanger is pleased to announce that Michael L. Slack and Ladd C. Sanger have received Board Certification in Aviation Law from the Texas Board of Legal Specialization. This achievement sets the two apart in Aviation Law, as only a handful of attorneys have received this certification in Texas.


Board certification means that an attorney has demonstrated special competence in a particular area of law. According to the Texas Board of Legal Specialization (TBLS), approximately 7% of Texas licensed attorneys are board certified, across 27 specialty areas. Board certified lawyers are the only lawyers in Texas allowed to refer to themselves as specialists and to display board certified credentials.


Texas is the largest single-state certification program for lawyers in the U.S., with Aviation Law becoming the latest area of specialty added by the TBLS in 2023.


The TBLS describes Aviation Law as the practice of law dealing with issues affecting aircraft and airport operations, aircraft ownership, aircraft navigation and maintenance, air traffic control safety, pilot licensing and certification requirements, spacecraft, and outer space. Lawyers in this area represent parties in transactions governed by or affected by aviation law, provide legal counsel with respect to various tax or regulatory matters, serve as legal counsel in civil aviation authority regulatory enforcement matters or other regulatory actions, provide legal counsel with respect to aviation-related insurance claims and coverage, and litigate aviation law disputes.


To become board certified in Aviation Law, applicants are required to meet the following qualifications:


  • Practice law full-time for at least 5 years as an active member of the State Bar of Texas;
  • At least 3 years of specified aviation law experience with a yearly minimum of 30% substantial involvement in aviation law matters;
  • Qualified vetted references from judges and lawyers in the area;
  • Complete 60 hours of TBLS approved continuing legal education in aviation law;
