Administrative Law

Our attorneys have decades of experience representing air carriers in challenges to fees, rates, charges, and taxes imposed by federal, state and local governments for use of airports and air traffic control facilities, and with regard to airport compliance with the federal requirements for operation of the airport. Our experience includes:

  • Three successive victories in the U.S. Court of Appeals for the DC Circuit challenging hundreds of millions of dollars in user fees imposed by the FAA for the utilization of air traffic control facilities and services by aircraft that do not take off or land in the United States (overflights), persuading three separate appellate panels that the FAA fees failed to comply with the statutory requirement that the ATC user fees be "cost based." E.g., Air Transport Ass'n of Canada v. FAA, 323 F.3d 1093 (DC Cir. 2003); Air Transport Ass'n of Canada v. FAA, 254 F.3d 1093 (DC Cir. 2001).

Product Liability Litigation

We have extensive experience defending airframe and engine manufacturers, overhaul facilities, Part 135 operators and other commercial aviation interests. A key focus of our Aviation and Aerospace Litigation Practice is on defending products liability claims, warranty matters and complex, aviation-related commercial disputes. We also have experience in FAA administrative actions arising from claimed product failures, poor maintenance and aircrew negligence.

We know and understand fully the products we defend.

We work closely with trusted, courtroom-proven consultants to visit accident scenes, review wreckage and participate in component inspection and testing. We take an aggressive, hands-on approach to defending cases that, at every stage of litigation, enhances our clients’ opportunities for a favorable outcome. To stay abreast of new developments, we attend manufacturer-sponsored training to gain deeper insight into the operation and maintenance nuances of aviation products.

Our in-depth experience defending a broad range of product design, defect and warranty claims made against leading airframe, engine, avionics and component manufacturers, includes:

  • Multi-district litigation based on alleged defects in pneumatic de-icing systems
  • Improper maintenance claims
  • Airworthiness claims resulting from airframe structural failure
