  • Record maintenance actions, discrepancies, and part changes into the company’s maintenance tracking system (e.g., AMOS, TRAX, IFS, CAMO), ensuring entries meet regulatory and audit requirements.
  • Support removal, inspection and replacement of accessories (fuel pumps, starters, IDGs, FADECs) under guidance; follow component handling and preservation practices to avoid contamination or damage.
  • Assist with borescope report generation and photo documentation for non-routine findings; ensure proper labeling, storage and escalation of suspect hardware to inspectors.
  • Participate in engine teardown and reassembly activities under supervision, learning inspection criteria, measurement techniques, and acceptance limits for rotating and static components.
  • Support non-destructive testing (NDT) prep and follow-up by preparing parts for inspection, performing basic visual inspection criteria, and coordinating with certified NDT technicians for magnetic particle/eddy current checks.
  • Maintain tool control and calibration awareness by checking torque wrenches, micrometers, dial indicators and other precision tools for correct calibration status; log usage and report issues.
  • Assist in tracking engine time, cycles, and life-limited parts; help prepare material for scheduled overhauls and ensure correct part numbers and serials are recorded for traceability.
  • Follow engine preservation, sealing and packaging procedures for storage or shipment, including identification of contamination risks and application of protective coatings as required.
  • Support the completion of Component Maintenance Manuals (CMM) tasks under mentor supervision, including measurements, clearances and adjustment procedures while documenting results.
  • Perform basic troubleshooting of fuel, oil and pneumatic systems related to engine operation, escalating complex defects to qualified technicians and supervisors.
  • Help maintain a safe, clean and organized engine shop and line area by performing housekeeping, compliance checks, and safe disposal of hazardous materials in accordance with environmental and safety regulations.
  • Participate in technical and classroom training programs, OEM familiarization courses, and on-the-job training modules to develop the skills required for certification and independent work.
  • Assist quality assurance and inspection teams during internal audits and regulatory inspections by preparing requested workpacks, records, and evidence of compliance.
  • Support parts requisition, kitting and inventory control for scheduled engine workscopes; help verify incoming parts against purchase orders and maintain rotable status records.
  • Perform assigned administrative tasks such as printing/amending workcards, compiling maintenance packages, and coordinating with maintenance control to ensure timely release to service.

Secondary Functions

  • Attend daily safety briefings, shift handovers and technical debriefs to ensure continuity of work and safe operation practices.
  • Participate in cross-functional teams to implement continuous improvement initiatives focused on engine maintenance efficiency and reliability.
  • Support ad-hoc tasks such as tooling projects, custom jigs fabrication under supervision, and updating internal job aids or checklists.
  • Contribute to the maintenance department’s training records by documenting completed training modules, proficiencies and competencies.
  • Help prepare management reports by compiling basic maintenance metrics (downtime, turn-time, defect recurrence) and escalating recurring issues for root cause analysis.
  • Assist other teams (airframe, avionics, logistics) to coordinate multi-disciplinary maintenance events and ensure timely completion of combined tasks.
  • Support the organization’s safety, environmental and human factors programs by reporting hazards, near-misses and participating in corrective action follow-up.
