	Gas Turbine System Technician		(Electrical) (Mechanical)	GSE GSM
	Gas Turbine System Technician are responsible for all gas turbine engines. They maintain propulsion machinery, including gears, shafting and controllable pitch propellers, assigned auxiliary equipment propulsion control systems, electrical and electronic circuitry up to the printed circuit module, and alarm and warning circuitry. They handle administrative tasks related to gas turbine propulsion system operation and maintenance.

Gas Turbine System Technician (GSE's) operate, repair and perform organizational and intermediate maintenance on electrical components of gas turbine engines, main propulsion machinery, auxiliary equipment,
propulsion control systems, and assigned electrical and electronic
circuitry up to the printed circuit and alarm warning
circuitry.

The duties performed by GSEs include:

operating electric plant main and propulsion control equipment;
locating circuit failures and replacing parts;
measuring current, voltage and resistance;
testing for shorts, grounds and continuity;
testing protective circuitry;
testing, servicing and replacing batteries;
performing preventive maintenance on digital data equipment and control and monitoring circuits;
measuring insulation resistance;
repairing electrical/electronic cables, wiring and connectors;
maintaining alarm, indicating and warning systems;
maintaining and repairing gas turbine engines and auxiliary equipment;
working with blueprints, schematics and charts;
performing administrative procedures related to gas turbine propulsion system operation and maintenance;
performing work area inspections;
operating standard test equipment;
stopping engines and checking for proper performance;
replacing and adjusting operating tolerance of contacts, microswitches, relay switches, pressure switches and temperature switches.

Working Environment

Gas turbine systems technicians usually work in engine rooms or shops that may be hot and noisy aboard many types of modern ships. At shore they may work at major repair or training facilities. Work
is physical and analytical (trouble-shooting) for electronic
components.

Credit Recommendations

The American Council on Education recommends that semester hour credits be awarded in the vocational certificate and lower-division bachelor's/associate's degree categories for courses taken in this rating on technical mathematics, applied physics, gas turbines, basic AC/DC theory and blueprint reading.

Qualifications and Interests

Personnel in this rating must have mechanical ability, manual dexterity and normal color perception. They should also have experience working with machines, in electronics/electrical fields and have had some courses in physics.

Opportunities

Opportunities for placement in this rating are excellent. Approximately 1,200 men and women work in this rating.
