What changes are coming to the CNR Process?
Two new classifications of CNR will be created (A & B):
Class A:
• Used if published Instructions for Continued Airworthiness (ICA) is not available to manage the subject issue
• Can provide supplementary maintenance recommendations until published ICA created/updated to address the issue
• Will include OEM Summarizing confirmed findings to Agencies
• Typically only new, emerging issues without ICA
Class B:
• General health and diagnostics monitoring recommendations that refer to existing ICA
• Majority of CNRs
• General health and diagnostics monitoring recommendations that refer to existing ICA
