The FAA's count is the general-aviation aircraft kept on the field (singles, twins, business jets, helicopters) from its Terminal Area Forecast, the latest year with an actual count; airline fleets are never counted as based anywhere, so a big airline airport shows a small number. The register section below shows how many aircraft are registered to owners in town, a different measure again.

5passengers boarded flights here in the FAA's fiscal year 2024

Takeoffs and landings a year about 13,750, the FAA's fiscal year 2024 (October 2023 to September 2024)

Local flights stay in the traffic pattern or nearby, often practice; travelling flights arrive from or leave for somewhere else. Counts at airports without a tower are the FAA's estimates. How this compares nationally: Airports by the numbers.

Who flies and works here aircraft registered in town, the companies, the examiners nearby

Aircraft registered in Montague from the FAA register

18 aircraft are registered to owners in Montague, California: 9 piston singles, 8 gliders, 1 piston twin. Not every one of them is based at this airport; the based-aircraft count above is the FAA's figure for this airport alone.

Individuals are counted, not named (the site's policy at this time). All aircraft registered in California.

Examiners and inspectors nearby designated by the FAA · within 50 nautical miles

No pilot examiner is based within 50 nautical miles, as far as the FAA's list places them. Also nearby: 3 aviation medical examiners, 1 airworthiness representative (maintenance), 1 airworthiness representative (manufacturing), 1 engineering representative, 1 training center examiner.

All 7 nearby, by kind, with contact details

What each kind does
  • AME: Aviation Medical Examiner: a doctor who issues the medical certificates pilots must hold.
  • DAR-T: Designated Airworthiness Representative, maintenance: issues airworthiness certificates and approvals for aircraft in service.
  • DAR-F: Designated Airworthiness Representative, manufacturing: issues airworthiness certificates for newly built aircraft and parts.
  • DER-T: Designated Engineering Representative: approves engineering data for repairs and alterations on the FAA's behalf.
  • DCTO-E: Designee at a certificated training organisation.

Designees are listed with the name and contact details the FAA publishes for them on its designee locator (read October 10, 2026): the FAA lists them so that pilots, mechanics and companies can find them. Private individuals are not named, the site's policy at this time. A designee who would rather not appear here can ask us through the contact address on the About page. Each designee is placed at the main public airport of the town the FAA lists (or the nearest one to its zip code), so "nearby" means the town, not an exact address. All examiners by state.
