What is the basis of certification for Hartzell propeller number HC-12X?

The basis of certification for Hartzell propeller number HC-12X is CFR Part 14, which pertains to the regulations concerning the certification of aviation products and their components, including propellers. Part 14 addresses the procedures for obtaining and maintaining the necessary certifications for products used in aviation, ensuring that they meet safety standards and operational effectiveness.

CFR Part 14 is significant because it outlines the complete framework for the approval process, including the documentation required and the assessments involved in confirming that the propeller complies with all applicable regulatory requirements. This emphasizes the importance of adhering to proper standards for safety and performance for aircraft components.

In the context of propeller certification, other options such as FAR 35, which focuses specifically on airworthiness standards for propellers, and FAR 23, which addresses the airworthiness standards for normal, utility, acrobatic, and commuter category airplanes, are certainly relevant but do not serve as the primary regulatory basis for the certification process as defined in CFR Part 14. These other references may provide standards or guidelines, yet the comprehensive certification structure provided in Part 14 is the correct basis for the Hartzell propeller HC-12X.
