Mechanic

An auto mechanic is a mechanic who services and repairs automobiles, sometimes specializing in one or more automobile brands or sometimes working with any brand. In fixing cars, their main role is to diagnose and repair the problem accurately.[1] Seasoned auto repair shops start with a (Digital) Inspection to determine the vehicle conditions, independent of the customers concern. Based on the concern, the inspection results and preventative maintenance needs, the mechanic/technician returns the findings to the service advisor who then gets approval for any or all of the proposed work. The approved work will be assigned to the mechanic on a work order. Their work may involve the repair of a specific part or the replacement of one or more parts as assemblies. Basic vehicle maintenance is a fundamental part of a mechanic's work in modern industrialized countries, while in others they are only consulted when a vehicle is already showing signs of malfunction.

Johann Georg Halske (30 July 1814 – 18 March 1890) was a German master mechanic.

An aircraft mechanic, aviation mechanic or aircraft maintenance technician (AMT) is a tradesperson who carries out aircraft maintenance and repairs. AMTs inspect and perform or supervise maintenance, repairs and alteration of aircraft and aircraft systems.

For a person who holds a mechanic certificate issued by the Federal Aviation Administration, the rules for certification, and for certificate-holders, are detailed in Subpart D of Part 65 of the Federal Aviation Regulations (FARs), which are part of Title 14 of the Code of Federal Regulations. The US certification is sometimes referred to by the FAA as the Aviation Maintenance Technician and is commonly referred to as the Airframe and Powerplant (A&P).
