Federal prosecutors have initiated legal proceedings against Walter Benjamin Bius and his Huntsville, Texas-based Prairie Flower Air Asset Company for allegedly operating an illegal charter service using deceptive aircraft leasing practices. The U.S. Attorney’s Office for the Southern District of Texas filed the civil penalty action on April 3, seeking millions in penalties for violations of FAA regulations.

According to the complaint, Bius operated Prairie Flower as a direct air carrier without obtaining the required FAA certification to demonstrate that the company met necessary safety standards. The action specifically targets the use of what industry insiders refer to as “sham dry leases”—a practice where an aircraft is purportedly leased to a client while the leasing company covertly maintains operational control of the aircraft.
