The purpose of this document is to establish guidelines that should be observed during initial design, production, and maintenance of aircraft components, and to present short-term and long-term strategies to minimize the costs and impacts associated with decreasing availability of components.

The goals of this report are to:

• Provide guidelines for designs that will be tolerant of component obsolescence, as referenced in ARINC Report 847, Section 9.0.

• Identify cost-effective methods for resolving component obsolescence issues.

• Facilitate information exchange, e.g., obsolescence solutions, databases, etc.

• Establish maintenance operation and support processes to address obsolescence.

• Recommend a standard practice for notification of obsolescence components (supplier to operator).
