SAE AS5553 Obsolescence Management Checklist

Obsolescence management is crucial because it helps prevent the need to source potentially counterfeit parts when original components become unavailable. It's an integral part of maintaining long-term compliance with SAE AS5553 and ensuring the continued reliability of aerospace and defense systems.

The checklist covers areas such as component lifecycle monitoring, obsolescence risk assessment, alternative part qualification processes, design for obsolescence strategies, and long-term storage and inventory management of critical components.

Obsolescence management strategies should be reviewed at least annually, with more frequent assessments for critical components or rapidly evolving technologies. The checklist should also be applied during new product development and major system upgrades.

The process should involve design engineers, supply chain managers, product lifecycle managers, procurement specialists, and quality assurance personnel. Collaboration with suppliers and sometimes customers is also crucial for effective obsolescence management.

This checklist includes items for identifying at-risk components early, developing contingency plans, qualifying alternative sources or substitute parts, and implementing design strategies that minimize the impact of component obsolescence, thereby reducing the risks associated with parts going out of production.
