Vehicle Maintenance

Install, adjust, or maintain mobile electronics communication equipment, including sound, sonar, security, navigation, and surveillance systems on trains, watercraft, or other mobile equipment.

• Inspect and test electrical systems and equipment to locate and diagnose malfunctions, using visual inspections, testing devices, and computer software.
• Reassemble and test equipment after repairs.
• Adjust, repair, or replace defective wiring and relays in ignition, lighting, air-conditioning, and safety control systems, using electrician's tools.

Operate, install, adjust, and maintain integrated computer/communications systems, consoles, simulators, and other data acquisition, test, and measurement instruments and equipment, which are used to launch, track, position, and evaluate air and space vehicles. May record and interpret test data.

• Test aircraft systems under simulated operational conditions, performing systems readiness tests and pre- and post-operational checkouts, to establish design or fabrication parameters.
• Identify required data, data acquisition plans, and test parameters, setting up equipment to conform to these specifications.
• Inspect, diagnose, maintain, and operate test setups and equipment to detect malfunctions.

Install, inspect, test, adjust, or repair avionics equipment, such as radar, radio, navigation, and missile control systems in aircraft or space vehicles.

• Test and troubleshoot instruments, components, and assemblies, using circuit testers, oscilloscopes, or voltmeters.
• Keep records of maintenance and repair work.
• Adjust, repair, or replace malfunctioning components or assemblies, using hand tools or soldering irons.

Diagnose, adjust, repair, or overhaul aircraft engines and assemblies, such as hydraulic and pneumatic systems.

• Inspect completed work to certify that maintenance meets standards and that aircraft are ready for operation.
• Read and interpret maintenance manuals, service bulletins, and other specifications to determine the feasibility and method of repairing or replacing malfunctioning or damaged components.
• Maintain repair logs, documenting all preventive and corrective aircraft maintenance.

Directly supervise and coordinate the activities of mechanics, installers, and repairers. May also advise customers on recommended services. Excludes team or work leaders.

• Inspect, test, and measure completed work, using devices such as hand tools or gauges to verify conformance to standards or repair requirements.
• Inspect and monitor work areas, examine tools and equipment, and provide employee safety training to prevent, detect, and correct unsafe conditions or violations of procedures and safety rules.
• Interpret specifications, blueprints, or job orders to construct templates and lay out reference points for workers.

Appraise automobile or other vehicle damage to determine repair costs for insurance claim settlement. Prepare insurance forms to indicate repair cost or cost estimates and recommendations. May seek agreement with automotive repair shop on repair costs.

• Evaluate practicality of repair as opposed to payment of market value of vehicle before accident.
• Review repair cost estimates with automobile repair shop to secure agreement on cost of repairs.
• Examine damaged vehicle to determine extent of structural, body, mechanical, electrical, or interior damage.

Diagnose, adjust, repair, or overhaul buses and trucks, or maintain and repair any type of diesel engines. Includes mechanics working primarily with automobile or marine diesel engines.

• Use handtools, such as screwdrivers, pliers, wrenches, pressure gauges, or precision instruments, as well as power tools, such as pneumatic wrenches, lathes, welding equipment, or jacks and hoists.
• Inspect brake systems, steering mechanisms, wheel bearings, and other important parts to ensure that they are in proper operating condition.
• Raise trucks, buses, and heavy parts or equipment using hydraulic jacks or hoists.

Repair and adjust electrical and mechanical equipment of inboard or inboard-outboard boat engines.

• Start motors and monitor performance for signs of malfunctioning, such as smoke, excessive vibration, or misfiring.
• Document inspection and test results and work performed or to be performed.
• Mount motors to boats, and operate boats at various speeds on waterways to conduct operational tests.
