Perform a variety of tear down, sub-assembly, assembly and performance tests operations on all types of overhauls and repair of gas turbine engines. Follow standard procedures, service bulletins, overhaul manuals, drawings, and special instructions sheets to plan and perform complex work. Working from inspection reports and rework instructions perform partial or complex engine tear down, visually checking for missing or faulty parts, nicks, scratches, etc. Repair and rework parts including reaming, shrink fitting, burring, stoning, polishing and changing parts, using a variety of mechanic's hand tools, jigs, fixtures, etc. Replace defective parts or assemblies and reassemble major and detail components checking that parts are assembled properly. Use a wide variety of Jigs, fixtures, test equipment, standard and special assembly tools. Check dimensions for backlash, endplay, fits, clearances, and other specified requirements with precision measuring instruments such as micrometers, dial indicators and a variety of fixed gauges working to close tolerances. Following standard test procedures and using established curves, charts, and test specifications, run prescribed tests. Regulate performance by setting and coordinating controls to obtain desired operational settings within close limits at specified points and within specified time limits. Record on log sheet appropriate engine performance data and make all required checks. After completion of test, remove necessary equipment and accessories and dismount engine. Occasionally enter test cell while engine is running to make minor adjustments. Watch for and recognize engine or equipment malfunctioning, diagnose cause of trouble and institute corrective actions. Initiate TDMR to correct deficiency in paperwork and books (AIS). Supply technical guidance and assist others to overcome technical difficulties. Help in the training of less senior co-workers. Inspect company and personal tooling daily for non-conformance such as nicks, burrs, broken and calibration date, and report deviations to supervisor/lead.
