Traceable OEM Aircraft Parts in MRO Processes
In the aviation industry, quality and safety are never compromised. Every small or large component in an aircraft’s structure must perform correctly under
the most severe flight conditions . For this reason , the concept of “traceable OEM parts” in MRO (Maintenance, Repair, and Overhaul) activities becomes
critically important . Using OEM (Original Equipment Manufacturer) parts that are fully traceable is one of the key pillars to ensuring flight safety and
compliance with strict international regulations such as EASA and FAA . These parts are not only manufactured according to the most precise design and
production standards but also have their complete production , inspection , and repair history fully documented . This feature guarantees that the aircraft
maintains the highest level of operational performance.
Why Is Traceability of Parts Important?
Preventing Use of Unauthorized or Counterfeit Parts
One of the greatest risks in aviation is the entry of counterfeit or undocumented parts into the maintenance cycle. A valid OEM serial number and precise
manufacturing and repair records indicate the part has come through a legitimate, approved path.
Facilitating Inspections and Audits
During periodic audits by regulatory authorities or even charter customers and aircraft owners , one of the first questions is always the presentation of
traceability documents for critical parts . Having complete documentation (Release Certificates , Trace Cards , and Non-incident Statements) reassures
operators and auditing bodies.
Monitoring Service Life and Scheduling Future Maintenance
Sensitive parts like engine components , hydraulic systems , or avionics usually have a defined life cycle (Life-limited Parts) . Accurate traceability helps
plan overhaul or replacement without error.
The Role of OEM Parts in MRO Repairs
OEM parts refer to components manufactured by the original manufacturer (aircraft maker or system manufacturer) or produced under OEM license
with the same standards. In MRO processes, using these parts has several important advantages:
Full compliance with original design: These parts have exactly the dimensional , material , and performance characteristics considered in the
aircraft’s initial design.
OEM warranty and accountability: If a defect occurs, the OEM is directly responsible, and warranty conditions often remain valid.
Assurance of correct engineering data: Repair manuals and specifications (CMM/AMM) are always based on OEM parts . Using these parts
guarantees repair compliance with documentation.
How Is the Parts Traceability Process Conducted in MRO?
Authorized MRO centers approved by EASA, FAA, or CAO usually have a precise parts management process. Key steps include:
Receiving Inspection: Parts purchased from OEM representatives enter the warehouse with Airworthiness documentation . Serial numbers , part
numbers, manufacturing dates, and quality documents are recorded in the ERP system.
Creating an Electronic History: Each part receives a digital passport where all subsequent operations—including installation , flights , repairs , or
tests—are recorded.
Pre-installation Checks: Before installation on an aircraft, traceability records are reviewed to confirm the part’s eligibility.
Archiving Documentation for Audits: All documents are kept for future inspections and to prove compliance with aviation regulations.
Operational Benefits of Using Traceable OEM Parts
Reducing AOG Costs
Using OEM parts with complete traceability records drastically lowers the likelihood of audit failures or mid-flight defects. This means less aircraft
downtime and minimal AOG (Aircraft on Ground) costs.
Extending Fleet Service Life
OEM parts, due to stricter quality control and engineering, generally last longer than unauthorized parts. Combining this advantage with lifecycle
management through traceability increases the overall economic life of the aircraft.
Easing Resale or Leasing
One major concern of aircraft owners during resale or lease transfers is providing complete records of installed parts. Having traceable OEM
parts simplifies and clarifies this process significantly.
Conclusion
Ultimately , traceable OEM aircraft parts form the backbone of fleet safety and efficiency . These parts ensure optimal performance and full
compliance with aviation regulations for airlines and operators . Authorized MRO centers that systematically manage traceability and OEM parts
usage play a crucial role in reducing operational risks and enhancing customer confidence . Therefore , investing in standard parts and processes
is essentially investing in a safer and more sustainable future for aviation.
