A fixed-pitch propeller must be marked with which identification data?

The correct identification data for a fixed-pitch propeller includes the builder's name, model designation, builder's serial number, production certificate number, and part number. This information is critical for maintaining accurate records and ensuring the propeller meets regulatory requirements and safety standards.

The builder's name and model designation allow for clear identification of the manufacturer and the specific design of the propeller. The builder's serial number provides a unique identifier for each propeller, which is essential for tracking maintenance history and any applicable service bulletins or airworthiness directives that may affect that specific unit. The production certificate number signifies that the propeller was manufactured under a regulated quality assurance system, which adds to its legitimacy and safety profile. Lastly, the part number is crucial for distinguishing the propeller from other models and configurations, ensuring compatibility and proper installation on aircraft.

In contrast, the other options do not encompass the comprehensive identification requirements necessary for a fixed-pitch propeller. For example, established ratings may not provide the detailed regulatory context needed, and some combinations omit critical identifiers like the production certificate number or serial number. Therefore, the information contained in the correct option ensures compliance with FAA regulations and enhances safety in aviation operations.
