Core Responsibilities

Primary Functions

Perform comprehensive disassembly, cleaning, inspection, repair, and reassembly of aircraft turbine engines, modules, and related components in accordance with Original Equipment Manufacturer (OEM) manuals.
Conduct detailed visual and dimensional inspections on engine components using precision measuring instruments such as micrometers, calipers, and gauges to ensure they meet strict serviceability limits.
Execute advanced boroscopic inspections on internal engine sections (hot and cold) to assess the health of components like turbine blades, nozzles, and combustion liners without full engine disassembly.
Interpret and apply complex information from technical manuals, engineering drawings, service bulletins, and airworthiness directives to guide all maintenance tasks.
Perform and document critical component replacements, modifications, and upgrades, ensuring full traceability and compliance with all applicable regulations.
Troubleshoot engine performance deficiencies, operational faults, and diagnostic codes by analyzing engine data and applying systematic problem-solving methodologies.
Prepare and balance high-speed rotating assemblies, including compressor and turbine rotors, to exacting standards to minimize vibration and extend engine life.
Perform non-destructive testing (NDT), such as fluorescent penetrant (FPI) or eddy current inspections, to detect surface and sub-surface cracks or flaws invisible to the naked eye.
Skillfully blend and polish compressor and turbine airfoils to repair damage from foreign objects (FOD) or operational wear, restoring aerodynamic performance.
Maintain meticulous and accurate records of all maintenance performed, parts used, and inspections completed in maintenance logs and digital systems, which form the legal airworthiness record of the engine.
Evaluate and determine the serviceability of engine parts and components, making critical decisions on whether to repair, replace, or retire items based on technical data.
Manage and maintain all calibrated tooling and specialized support equipment, ensuring it is in perfect working order for safe and accurate maintenance.
Prepare engines for testing, assist in post-test analysis, and perform final inspections and preservation for storage or installation.
Adhere to the highest standards of safety, quality, and workplace organization (5S/6S principles), maintaining a clean and hazard-free work environment.
Interface with engineering and quality departments to provide feedback on maintenance procedures and seek clarification on technical dispositions or repairs.

Secondary Functions

Support ad-hoc data requests and provide technical insight for reliability analysis and fleet health monitoring programs.
Mentor and provide on-the-job training for junior technicians and apprentices, sharing knowledge and ensuring best practices are followed.
Actively participate in continuous improvement initiatives, suggesting process enhancements to improve safety, quality, and efficiency.
Assist with inventory management of spare parts, tooling, and consumables, ensuring necessary items are available for planned and unplanned work.
Collaborate with maintenance planners to ensure work scopes are well-defined and achievable within scheduled ground time.
