Plane Sense introduces aircraft owners and operators, or prospective aircraft owners and operators, to basic information about the requirements involved in acquiring, owning, operating, and maintaining a private aircraft. This handbook can be a valuable reference tool for anyone who would like to review the "nuts and bolts" of aircraft ownership. The FAA has also added information for aviation enthusiasts who own (or are interested in owning) lightsport aircraft, a new and evolving sector of the general aviation marketplace. This handbook highlights regulations and regulatory guidance material, as well as providing advice regarding where to locate answers to your questions. While Plane Sense cannot cover every issue faced by aircraft owners and operators, this handbook is intended to be a useful guide and will help you locate the resources to assist you. This publication supersedes FAA-8083-19, which was reprinted with editorial updates in 2003.
