This authority is responsible for overseeing the certification and regulation of rocket motors, ensuring that any modifications or changes are evaluated and addressed according to established safety standards and guidelines.

Reporting changes to the original certifying authority allows for a proper assessment of how the modifications might affect the motor's performance and safety. This ensures that any new risks introduced by the changes are properly managed and that the motor remains compliant with safety regulations.

Understanding who to report changes to is essential in maintaining safe practices within the high power rocketry community. It fosters accountability and adherence to safety protocols, which are critical in this field.
