The State of U.S. Aircraft Maintenance

A free, openly licensed dataset of FAA-certificated Airframe & Powerplant (A&P) mechanics and Part 145 repair stations, cleaned and geocoded from public FAA records. Browse the numbers by state below, or download the full dataset.


Choropleth map of the United States shaded by FAA A&P mechanics per 100 based aircraft. Oklahoma (294.7), Hawaii (261.3), and Georgia (249.4) are densest; North Dakota (32.1), South Dakota (44.1), and Montana (44.9) are thinnest. Each state is labelled with its exact ratio.
A&P mechanics per 100 based aircraft, by state. Color and label both show this ratio. Sources: FAA Airmen Certification Database (cycle CS052026) and FAA Terminal Area Forecast (2024 based aircraft).

Sources & Definitions

Sources. FAA Airmen Certification Database (A&P mechanics and IA holders), FAA NASR (public-use airports), and the FAA Part 145 repair-station registry. All are public records; this site refreshes them monthly (data as of JUNE 2026).

What's counted. "A&P Mechanics" counts all FAA-certificated Airframe & Powerplant certificate holders by state. Of the 233,886 nationwide, 233,886 have a public street address on file and are listed in this directory; the FAA withholds the address for the rest. "IA" is the subset additionally holding Inspection Authorization. "Repair Stations" are FAA-certified Part 145 facilities. Counts are supply-side; a per-registered-aircraft ratio will be added when FAA aircraft-registration data is joined.
