Boolean search strings for aircraft mechanics: A&P variants, IA, line or heavy maintenance, avionics and structures

An aircraft mechanic search works when the string writes the FAA mechanic certificate every way mechanics do (A&P, "airframe and powerplant", aircraft or aviation maintenance technician), names the work (line, base or heavy check, engines, avionics, structures) and the aircraft family, and keeps automotive, diesel and HVAC mechanics out. "Mechanic" alone returns every trade that turns a wrench; "aircraft" alone returns assemblers, ramp agents and engineers.

Below are ten strings by kind of maintenance, the certificate terms behind them, and what LinkedIn, Indeed and Google support as of November 2026. For the operators themselves, see Boolean search strings for recruiters; for the first call, see the aircraft mechanic screening questions.

Certificates, ratings and authorizations that change what a mechanic search finds

• The certificate. Mechanic certification is federal, under 14 CFR Part 65, Subpart D. Under section 65.77, applicants either graduate from a certificated aviation maintenance technician school or document practical experience, as of November 2026. Under section 65.83, a mechanic may not exercise the certificate without recent experience, generally six months of work as a mechanic within the preceding 24, which is why a gap in the work history is a screening question.
• The inspection authorization. Under section 65.91, an IA applicant must have held both ratings for at least three years, among other conditions, and under section 65.95 the holder can approve aircraft for return to service after major repairs and alterations and perform annual inspections. Mechanics write "A&P/IA", "A&P IA" or "inspection authorization".
• The repairman certificate. Under section 65.101, it goes to a person employed for a specific job by a certificated repair station, commercial operator or air carrier and recommended by that employer. It does not travel to a new employer the way an A&P does.
• Drug testing. Aircraft maintenance and preventive maintenance are on the FAA's list of safety-sensitive functions in 14 CFR 120.105, including for contractors at any tier. That is a hiring step, not a search term; the drug testing guide covers how it sits beside state rules.

Ten Boolean strings by kind of maintenance

Swap in the aircraft, operation and station from your own intake; these are examples. None of them uses age, military service or any other protected characteristic: mechanics trained anywhere hold the same FAA certificate, so search on that.

Line and heavy maintenance

1. A&P line mechanic at an airline — LinkedIn general search
("a&p mechanic" OR "airframe and powerplant" OR "aircraft maintenance technician" OR "line mechanic") AND ("line maintenance" OR "part 121" OR "overnight checks") NOT (automotive OR diesel OR hvac OR recruiter)

2. Heavy check or base maintenance technician — LinkedIn Recruiter, Job titles + Keywords filters
("aircraft mechanic" OR "aviation maintenance technician" OR "a&p technician") AND ("heavy check" OR "c-check" OR "base maintenance" OR mro) NOT ("aircraft cleaner" OR "parts clerk" OR "ramp agent")

3. Inspector with an IA — LinkedIn general search
("inspection authorization" OR "a&p/ia" OR "a&p ia") AND ("annual inspections" OR "major repairs" OR "form 337") NOT ("flight instructor" OR student)

Specialties

4. Avionics technician — Indeed Smart Sourcing
title: ("avionics technician" OR "avionics installer" OR "avionics mechanic") AND skill: ("wiring diagrams" OR troubleshooting OR "glass cockpit" OR autopilot) NOT ("car audio" OR "home theater")

5. Structures or sheet metal mechanic — Indeed Smart Sourcing
title: ("structures mechanic" OR "sheet metal mechanic" OR "aircraft structures technician") AND skill: ("structural repair manual" OR srm OR riveting OR "composite repair") NOT (hvac OR ductwork OR "sheet metal worker")

6. Powerplant or engine shop mechanic — LinkedIn general search
("powerplant mechanic" OR "engine mechanic" OR "a&p mechanic") AND (borescope OR "engine change" OR "hot section" OR "turbine engine") NOT (automotive OR "small engine" OR marine)

7. Helicopter mechanic — LinkedIn general search
("helicopter mechanic" OR "rotorcraft mechanic" OR "a&p mechanic") AND (helicopter OR rotorcraft OR "track and balance") NOT ("helicopter pilot" OR "flight nurse")

General aviation, new graduates and leads

8. General aviation shop mechanic — Indeed Smart Sourcing
title: ("a&p mechanic" OR "aircraft mechanic" OR "airframe and powerplant mechanic") AND skill: ("100-hour inspections" OR "annual inspections" OR "piston engines") NOT (automotive OR "auto mechanic")

9. Recent maintenance school graduate — Indeed Smart Sourcing
("aviation maintenance technician" OR "aircraft maintenance technician" OR "airframe and powerplant") AND fieldofstudy: ("aviation maintenance" OR "aviation maintenance technology") AND ("part 147" OR "amt school")

10. Maintenance lead or controller — LinkedIn Recruiter, Job titles filter
("lead mechanic" OR "maintenance supervisor" OR "maintenance controller" OR "director of maintenance") AND ("a&p" OR "airframe and powerplant") AND ("part 135" OR "part 121" OR "part 145") NOT (facilities OR building OR fleet)

For a Google X-ray, write the certificate out, since Google's operators page says nothing about the ampersand: site:linkedin.com/in "airframe and powerplant" "inspection authorization" "wichita" -jobs -recruiter. Public profiles can be months old, so treat results as names to check.

What LinkedIn, Indeed and Google actually support

As of November 2026, LinkedIn's Boolean help page requires AND, OR and NOT in capitals, supports quotes and parentheses, and does not support wildcards. It does not say how an ampersand is handled, so every string above pairs "a&p" with "airframe and powerplant". LinkedIn Recruiter's Boolean page lists Job titles, Companies and Skills and Assessments among its Boolean filters and warns that too many facets in one query can cause a search result issue.

Indeed's repair, maintenance and installation guide, last updated March 31, 2026, shows AND, OR, NOT, quotes and parentheses, and field searches including skill: and fieldofstudy:, with mechanic examples. Indeed's advanced search post adds title: for the most recent title, which strings 4, 5 and 8 use to keep HVAC and auto profiles out.

Google's search operators page documents quotes, site:, the minus sign and filetype:, but not OR, so the X-ray above uses one phrase per idea. To check a certificate, use the FAA's Airmen Inquiry: it searches by last name with optional first name, city or state, and does not display the certificate number, Social Security number or date of birth. It confirms a candidate you found; it does not list candidates.

Narrowing by operation, aircraft and shift

The operation comes first. Airline line mechanics write about overnight checks, deferrals and turn times; heavy check technicians write about task cards, C-checks and hangar lines; repair station and component shop technicians write about the parts they overhaul; general aviation mechanics write about annuals and 100-hour inspections on piston aircraft. One operation block narrows a list faster than any certificate term.

The aircraft and engine family comes next. A mechanic with five years on regional jets is a faster start on the client's regional fleet than one with the same years on piston singles, even with the same certificate. Put the client's family in a required block and similar families as OR terms if the client will train.

Shift and badging decide many placements. Line stations run nights, AOG teams travel at short notice, and at covered airports nobody gets unescorted access authority without a fingerprint-based criminal history records check (49 CFR 1542.209). Leave those out of the string and ask on the call.

False positives worth excluding with NOT

• Other mechanics. Automotive, diesel, marine and small engine mechanics share engines, hydraulics and troubleshooting. Exclude them by name, and see the diesel mechanic screening questions if a client actually needs one.
• HVAC sheet metal. HVAC sheet metal workers write about sheet metal and fabrication. Exclude hvac and ductwork from structures searches, as string 5 does.
• Ramp, cleaning and stores staff. Ramp agents, fuelers, aircraft cleaners and parts clerks work beside mechanics and list the same aircraft. Exclude them by title.
• Engineers and assemblers. Aerospace engineers design aircraft and production assemblers build them; neither is a maintenance role unless the client says so. Exclude "aerospace engineer" and "assembler" when the role signs off maintenance.
• Students and recruiters. Maintenance school students list both ratings as goals; aviation recruiters list every certificate. Use string 9 for new graduates on purpose, and exclude "recruiter" everywhere else.

A worked example: three passes on a structures search

An invented search, shown as it actually gets narrowed.

The trade words found the structures people; the operation words found the ones who already work heavy checks.

What a search cannot verify

A string can find someone whose profile shows the right certificate, specialty and operation. It cannot confirm recent experience under section 65.83, show how carefully the mechanic writes a logbook entry, or tell you whether they will pass the drug test and badge check. The aircraft mechanic screening questions cover certificates, recent experience and paperwork, the interview guide for aviation maintenance roles covers the manual and hands-on exercises, and the Boolean strings for pilots cover the flight side of the same operators.
