Mechanic

A mechanic is a skilled tradesperson who uses tools, mechanical knowledge, and diagnostic methods to install, inspect, maintain, diagnose, and repair machinery and vehicles. Mechanics work across sectors and may specialize in particular systems or equipment. They differ from engineers, who typically focus on design, planning, and optimization rather than hands-on repair.

Common specialties include automotive mechanics, diesel mechanics, aircraft mechanics, marine mechanics, and industrial machinery mechanics. Typical workplaces include repair shops, dealerships, fleets, factories, airports, and shipyards. Core duties include preventive maintenance, fault diagnosis, part replacement, engine and transmission work, brake and suspension systems, and the inspection and repair of hydraulic, pneumatic, and electrical components.

Tools and methods: mechanics rely on hand tools, power tools, diagnostic scanners, and testing equipment. They interpret service manuals, schematics, and technical bulletins and apply systematic troubleshooting techniques to identify root causes and plan repairs.

Training and qualifications: most mechanics complete vocational education or apprenticeships. Certifications such as ASE in the United States or City & Guilds qualifications in the United Kingdom and Europe are common, though requirements vary by jurisdiction. Some roles require licensing or employer-based certification.

Impact and career prospects: mechanics are essential to transportation, manufacturing, and infrastructure, contributing to safety, efficiency, and reliability. Career paths include lead mechanic, foreman, supervisor, or specialized technician. Ongoing training is common as technology evolves.
