CDCCL stands for?

• A. Critical Design Configuration Control Limitations
• B. Critical Data Configuration and Control Limits
• C. Cabin Design Configuration Control Levels
• D. Control Design and Configuration Limitations

Answer: (A)

CDCCL stands for Critical Design Configuration Control Limitations. This term identifies the specific design features or configurations that are considered critical to the aircraft’s safe operation. The “critical design” part points to aspects of the design that, if changed, could affect safety or airworthiness. The “control” and “limitations” parts mean there is a formal process to manage any changes to these features and that only approved configurations are permitted. Any modification to a CDCCL item requires proper documentation, authorization, and often re-certification before the aircraft can be flown. The other options use nonstandard wording and don’t reflect the established term used to govern how critical design configurations are kept within safe, approved limits.
