Overview
IEC 62239-1:2018 is an international standard developed by the International Electrotechnical Commission (IEC) that sets forth comprehensive requirements for preparing and maintaining an Electronic Components Management Plan (ECMP) specifically for avionics applications. This standard helps avionics Original Equipment Manufacturers (OEMs) and related stakeholders ensure that electronic components used in avionics equipment are selected, applied, and managed within controlled processes compatible with the critical safety and performance demands of the aerospace environment.
As the first part of the process management for avionics management plans series, IEC 62239-1:2018 replaces the previous technical specification from 2015, incorporating significant technical updates. These include alignment with other key standards and specifications such as SAE EIA-STD-4899 and SAE AS6081, introducing guidance on component technical erratum analysis, and updating references to widely recognized electronic component qualification and process management schemes.
Key Topics
IEC 62239-1:2018 addresses the following core areas critical to avionics electronic components management:
-
Component Selection Criteria
Focus on proper application conditions, availability, durability, and identification of electronic components to guarantee compatibility and long-term sustainment.
-
Component Application Requirements
Guidelines on electromagnetic compatibility, derating and stress analysis, thermal and mechanical analysis, testing, maintainability, and radiation environment considerations.
-
Component Qualification and Approval
Establishes minimum qualification requirements, quality management by original component manufacturers (OCMs), and approvals required for suppliers and subcontractors.
-
Continuous Quality Assurance
Procedures for ongoing monitoring of component quality, design or manufacturing process changes, and in-house audit practices.
-
Component Dependability and Obsolescence Management
Strategies for assessing component reliability, availability risks, obsolescence surveillance, and proactive mitigation measures.
-
Configuration Control
Management of alternative components and sources, equipment change documentation, and customer notifications to maintain traceability and compliance.
-
Plan Administration
Roles and responsibilities of the plan focal point, plan applicability, implementation, acceptance, and maintenance requirements ensuring the ECMP’s efficacy and alignment with customer and regulatory expectations.
Additionally, the standard provides informative annexes including a requirement matrix, qualification guidelines, and cross-references to SAE standards for detailed implementation support.
Applications
IEC 62239-1:2018 is particularly essential for:
-
Avionics Original Equipment Manufacturers (OEMs)
To develop robust ECMPs that comply with international industry best practices, minimizing risk related to electronic component failures in aerospace systems.
-
Aerospace Suppliers and Subcontractors
Ensuring that component selection and application adhere to strict avionics quality and reliability criteria, which is crucial for certification and operational safety.
-
Quality Assurance and Compliance Teams
Implementing controlled processes for component qualification, traceability, and obsolescence management to maintain supply chain integrity and regulatory compliance.
-
Engineering and Design Teams in Avionics
Applying technical criteria such as electromagnetic compatibility, thermal and mechanical analysis, and risk assessment during product design and lifecycle management.
-
Regulatory Bodies and Certification Authorities
Using IEC 62239-1 as a benchmark to evaluate compliance of avionics components with industry standards critical to airworthiness and safety.
Related Standards
IEC 62239-1:2018 aligns and references several key standards and technical specifications to provide a holistic approach to avionics electronic components management:
-
SAE EIA-STD-4899
Provides detailed guidance supporting the preparation and compliance verification of the ECMP requirements.
-
