Derrick J. Hahn

Lead Attorney


(214) 744-3200

Derrick Hahn earned his law degree after spending more than 15 years in the aviation industry as an A & P Mechanic/IA and general manager of an FBO (Fixed Base Operation) in Phoenix, Arizona.

He became a lawyer specializing in aviation law because, when the need arose, he could never find a lawyer that understood aviation-related business and regulatory issues. After spending several years practicing law in Nebraska, Hahn relocated to Dallas and created the Hahn Law Firm. He received his law degree from the University of Nebraska and earned his BS in Aviation Management and MBA degrees from Western International University in Phoenix.

He is uniquely qualified to provide expertise and experienced legal services to clients with aviation related matters.  He has represented pilots, mechanics, repair stations, and charter operators against enforcement actions by the FAA, some of which were before the NTSB and various US Courts of Appeal.  He has himself been an expert witness for other law firms in aviation related cases litigated by those firms.
