A 5010 is not a sweet onion. Each airport has an “Airport Master Record” (FAA Form 5010) which is the “official” record for the airport. It describes who owns the airport, its use (public or private), and details about the facility such as runways, runway length, obstructions, and other pertinent information.
Inspectors use the Master Record to verify data and note any changes. The inspection serves two main purposes. First, to insure the airport meets minimum safety standards, and second, to assist the airport owner in operation of their facility. Inspectors check not only to make sure the airport meets applicable regulations, but often will make recommendations on more efficient operating procedures. A copy of the updated 5010 Airport Master Record is sent to the National Flight Data Center in Washington D.C. They check the accuracy of the information and include it in the next edition of the federal Airport/Facility Directory (A/FD), and distribute updated data to FAA offices, and Flight Service Stations (FSS).
The airport owner receives a copy of the revised Master Record and a letter explaining deficiencies that must be corrected.
