Manufacturing Aircraft Parts According to International Standards
The aerospace industry, as one of the most sensitive and complex industries in the world, is directly linked to human lives. For this reason, the manufacturing of
every small part in an aircraft must be carried out in accordance with the most precise international standards. These standards ensure that parts produced any
where in the world meet a specific level of quality, durability, and safety. In this article, we will explore the importance of manufacturing aircraft parts according
to international standards and their impact on flight safety and reliability.
Why Is Adhering to International Standards Important in Aircraft Parts Manufacturing
An aircraft is made up of hundreds of thousands of small and large components, each playing a vital role in overall performance. Even a defect in a small nut
or washer can lead to a major accident . For this reason , global organizations such as the FAA (Federal Aviation Administration) , EASA (European Union
Aviation Safety Agency), and ICAO (International Civil Aviation Organization) have developed very strict guidelines for the design, manufacture, and testing of
aircraft parts.
These standards cover topics such as:
Selection and testing of raw materials
Manufacturing and machining processes
Welding and assembly methods
Non-destructive testing (NDT)
Multi-stage quality control
Comprehensive documentation
Compliance with these guidelines not only ensures safety but also allows parts produced in any country to be used on aircraft designed or built in other countries.
The Process of Manufacturing Parts to International Standards
Selection of Raw Materials According to Global Standards:
To manufacture any part, internationally approved alloys or composite materials must first be selected. These materials come with quality certificates and chemical
analysis reports before entering the production line.
Precision Machining:
Aircraft parts are manufactured with extremely tight tolerances(sometimes as small as a few microns).This requires advanced CNC machines and skilled operators.
Welding and Assembly According to Aerospace Codes:
Welding of aircraft parts must follow guidelines such as AWS D17.1 or similar standards, which specify the welding method, type of weld, type of electrode, and
even environmental conditions during the welding process.
Non-Destructive Testing (NDT):
After manufacturing, parts undergo tests such as Ultrasonic Testing (UT) , Penetrant Testing (PT) , Magnetic Particle Testing (MT) , and Radiographic Testing (RT)
to detect internal cracks or cavities.
Final Quality Control and Documentation:
Each part comes with a quality certificate, approved technical drawings, and test records, which are kept for years if needed.
Advantages of Manufacturing Parts According to International Standards
Increased Safety: The primary goal of these standards is to protect the lives of passengers.
Export Capability: With international standards, part manufacturers can sell their products to airlines or aircraft manufacturers in other countries.
Assurance of Compatibility: Parts made to these standards can be seamlessly installed on aircraft produced in different countries.
Reduced Maintenance Costs: Higher-quality parts reduce failures and extend service intervals.
Iran’s Position on This Path
In recent years, several Iranian knowledge-based companies and industrial factories have succeeded in obtaining some international standards such as AS9100
(specific to quality
management in aerospace industries) and even certifications from foreign companies for the manufacture of certain components . This indicates a movement
of the domestic industry towards meeting global requirements. Moreover , given the Iranian fleet’s need for standard spare parts , developing these capabilities
reduces foreign currency dependence and increases the reliability of the domestic fleet.
Conclusion
Manufacturing aircraft parts according to international standards is far more than a luxury requirement . It is , in fact, a direct route to flight safety , industrial
credibility, and export development . The more the Iranian aerospace industry invests in and commits to this path , the greater the economic and strategic
achievements will be. A future where domestic manufacturers can produce world-standard parts will not only transform the aviation sector but also have a
profound impact on Iran’s entire knowledge-based economy.
