Core Responsibilities

Primary Functions

Disassemble, identify, and prepare jet engine components (compressor blades, turbine disks, seals, bearings, shafts, combustor liners) for inspection and overhaul following work packs, OEM manuals and fully controlled procedures, ensuring all parts are correctly tagged and logged.
Perform detailed visual inspections and borescope inspections of internal turbine components to identify cracks, erosion, corrosion, foreign object damage (FOD) and service life limits, escalating findings to senior staff and recording observations in inspection reports.
Carry out non‑destructive testing (NDT) under supervision — including dye penetrant, eddy current and ultrasonic testing — to detect subsurface defects and prepare NDT reports for certification and disposition.
Measure and record critical dimensions using micrometers, vernier calipers, dial indicators, bore gauges and height stands and compare readings to engineering tolerances and drawing specifications to determine part serviceability.
Execute precision hand finishing operations such as lapping, honing, blending and reconditioning of sealing surfaces and blade edges to OEM finish standards, ensuring surface integrity and dimensional accuracy.
Support machining and preparation tasks including deburring, reaming, drilling, countersinking, stud removal and fitted part assembly on manual machines and jigs under instruction, following safety and quality checks.
Strip, clean and chemically process components (e.g., solvent immersion, alkaline cleaning, anodic cleaning) and prepare items for further inspection or repair, maintaining chemical safety data sheet (SDS) compliance.
Reassemble overhauled components in accordance with torque settings, fastening sequences and assembly instructions; apply correct locking compounds, seals and spacers; verify running clearances and end‑float as required.
Fit, remove and set bearing and seal assemblies using presses, pullers, and hand tools while observing correct heat/cold fitting procedures and safety protocols.
Assist in balancing rotating assemblies (rotors, compressor spools) using balancing rigs and interpret imbalance data to direct corrective machining or trimming activities.
Prepare and update MRO and ERP system records (e.g., SAP, AMOS, IFS) including work completion notes, life-limited part tagging, serial number reconciliation and certificate attachment for regulatory compliance.
Execute minor structural repairs such as rivet replacement, fastening repair, stud extraction and chase-out operations under guidance, ensuring repair methods align with approved repair schemes.
Follow approved work instructions and engineering drawings to perform dimensional checks and mark up components for further machining or rejection; collaborate with engineers on deviation requests when necessary.
Participate in blinding, blanking and packaging of serviceable components to customer and shipping standards, ensuring traceability and protective preservation for storage or dispatch.
Support heat‑treatment and coating process steps by preparing components for processes such as aluminizing, shot peening, plating and coating inspections; verify vendor certificates and returned goods against specification.
Maintain shop tooling, jigs and fixtures; conduct basic maintenance, calibration checks and daily pre‑use inspections of hand tools and measuring equipment to ensure consistent accuracy and safety.
Assist with tear‑down and build‑up inspections of modules and sub‑assemblies, logging discrepant part numbers and preparing discrepant material reports (DMRs) following internal quality procedures.
Adhere strictly to environmental, health and safety (EHS) policies, including hazardous material handling, workspace cleanliness, FOD control, confined‑space awareness and PPE use at all times.
Support first‑line troubleshooting of component malfunctions during test runs and ground checks, collecting data and performing basic diagnostic steps to assist senior technicians and test engineers.
Participate in continuous improvement and lean initiatives by suggesting process improvements, documenting time‑saving workarounds and supporting 5S/visual management in the component shop.
Complete training modules, on‑the‑job assessments and competency sign‑offs as part of the apprenticeship framework, demonstrating progression through practical and theoretical milestones.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist scheduling and logistics teams by providing realistic turnaround time estimates for component jobs and highlighting potential bottlenecks.
Support quality audits by preparing documentation packs and participating in internal and external audit walkthroughs.
Help maintain stock and consumables for the component shop, monitoring levels and raising purchase requests as required.
Mentor newer apprentices on basic shop safety, tool use and shop etiquette as competency grows.
