 ACA volunteers also work with aviation organizations such as the Aircraft Owners and Pilots Association, the Experimental Aircraft Association, the National Business Aircraft Association, the General Aviation Manufacturers Association, the National Aeronautic Association, and many others to promote the work of the volunteers who run the groups and provide the flights.ACA representatives also work with the Federal Aviation Administration and the National Transportation Safety Board to ensure that appropriate regulations apply to the flights in the interests of maximizing their benefit to those in need and our communities while enhancing the safety of flight.Most Public Benefit Flying organizations are chartered as non-profit organizations, permitting their members to take the costs of a flight as a charitable donation.
