49 U.S.C. § 46305 — Actions to recover civil penalties

A civil penalty under this chapter may be collected by bringing a civil action against the person subject to the penalty, a civil action in rem against an aircraft subject to a lien for a penalty, or both. The action shall conform as nearly as practicable to a civil action in admiralty, regardless of the place an aircraft in a civil action in rem is seized. However, a party may demand a jury trial of an issue of fact in an action involving a civil penalty under this chapter (except a penalty imposed by the Secretary of Transportation that formerly was imposed by the Civil Aeronautics Board) if the value of the matter in controversy is more than $20. Issues of fact tried by a jury may be reexamined only under common law rules.
