Levels of Avionics Maintenance (LAM) Working Group and Test Equipment Guidance (TEG) Working Group

Last Update: April 19, 2012

ARINC 663: Data Requirements for Avionics Component Maintenance

• To review the specific definition for each level for avionics maintenance (LAM) taking into account current test developments, evolution of test technologies, and maintenance philosophies.

ARINC 602A-2: Test Equipment Guidance (TEG)

• Review contents according to state-of-the-art test technologies, requirements, and implementations.
• Integrate issues and solutions related to the “Use of Aircraft Parts as Test Equipment” (Ref.: Symposium during AMC 2010).
• Remodeling/restructuring of ARINC 602A-2 as necessary.
• The effort will also include reviews of references to/from other applicable ARINC standards and guidelines.

ARINC 625: Industry Guide For Component Test Development and Management

A review of ARINC 625 and feedback from the industry indicates that enhancements may be necessary to bring the document into line with existing practices and to improve readability:

• Changes due to technological evolution of aircraft components and test technologies.
• Changes in relation to the current review of ARINC Guidelines 602A-2 “Test Equipment Guidance (TEG)” and 663 “Data Requirements for Avionics Component Maintenance”

ARINC Report 668: Guidance for Tool and Test Equipment (TTE) Equivalency

A review and feedback from the industry indicates that the current requirements for TTE equivalency within ARINC 668 might be too stringent, i.e. imposing unnecessary effort/cost for implementation and operation of ARINC 668 related processes. A rework of ARINC668 will provide a new philosophy regarding TTE equivalency determination:

• Detailed equivalency determination including documentation will only be necessary for TTE involved in Return to Service Testing (RTS) and those TTE critical to safety, performance, and cost.
• Equivalency of other TTE will be covered by defined procedures (e.g. standard practices) based on the quality manual of the individual maintenance organization.
• Review the ARINC 668 document to ensure accuracy and consistency with evolving industry practices.
