Aircraft Mechanic Salary in California 2026,
$86,100 Median | BLS Data by City

California aircraft mechanics earn a median $86,100 a year, $41.40 an hour, per BLS OEWS May 2025, with the middle half between $68,390 and $99,650 and a full range of $53,860 to $116,690. That is 7.8% above the $79,870 national median, before California's income tax.

San Jose-Sunnyvale-Santa Clara at $98,760, then Yuba City at $97,240, San Francisco-Oakland-Fremont at $93,400, Bakersfield-Delano at $91,750 and San Diego-Chula Vista-Carlsbad at $87,560. Yuba City ranking second is genuine — northern California's agricultural aviation and defence-adjacent maintenance work pays close to Bay Area business aviation rates in a far cheaper market.

No. The governing credential is the FAA Airframe and Powerplant certificate, issued federally, and California adds no state licence on top of it. The certificate comes through an FAA-approved Part 147 aviation maintenance technician school or documented practical experience, followed by written, oral and practical tests. Inspection Authorization is the federal credential above it, allowing approval of major repairs and annual inspections.

California's income tax is progressive to 13.3%, and all wages carry a 1.3% State Disability Insurance contribution with no cap in 2026. At the median of $86,100 a mechanic sits in the middle brackets. Because overtime is a large part of real earnings in this trade — heavy checks, aircraft-on-ground recovery, night line maintenance — the state's marginal rates apply to the most variable part of the income.

Business and corporate aviation, Inspection Authorization work, and defence sustainment. Corporate flight departments in the Bay Area and Southern California pay above airline line maintenance for smaller crews with broader responsibility; an FAA Inspection Authorization permits approval of major repairs and annual inspections and commands a premium anywhere; and defence sustainment work adds a clearance requirement and a corresponding rate. Together these are what the $99,650 seventy-fifth percentile and the $116,690 ninetieth reflect.

Because heavy maintenance left. Airline heavy check and overhaul work migrated decades ago to lower-cost states and offshore facilities, and what remains in California is line maintenance at the major airports, business and corporate aviation, defence sustainment and a substantial agricultural aviation sector in the Central Valley. That mix explains a location quotient of 0.78 alongside a median 7.8% above the national figure: fewer jobs, but weighted toward the better-paid categories.

The annualised median does not isolate overtime, and this trade runs on it — heavy check cycles, aircraft-on-ground recovery and night line maintenance all generate premium hours that materially raise real annual earnings above $86,100. On the other side, the $53,860 tenth percentile reflects uncertificated technicians working under supervision rather than A&P holders. Read the $68,390 twenty-fifth percentile as the certificated floor.

Shift, licence and type. Line maintenance runs overnight because aircraft fly during the day, and night differentials are standard. The FAA Inspection Authorization is the single credential that most changes earning capacity, since it permits approval of major repairs and annual inspections. And airframe type experience — specific transport category aircraft, or particular business jet families — is what employers actually recruit for, which is why a mechanic with the right type on a corporate flight department can sit near the $116,690 ninetieth percentile.
