Final answer:
Regulations for airworthiness are found in specific parts of a country's Civil Aviation Regulations (CAR), which often include an Airworthiness Manual. The correct part of the CAR depends on the country's regulatory structure, with 'CAR Part V' being an example of where airworthiness regulations would be located in Canada.
Step-by-step explanation:
The regulations for airworthiness are typically found in a country's Civil Aviation Regulations (CAR). Specifically, in many jurisdictions, you will be able to find the airworthiness regulations detailed in the Airworthiness Manual, which is often part of the overarching Civil Aviation Regulations. However, looking at the options provided in your question: 'The Airworthiness Manual,' 'CAR part VI,' 'CAR 625', and 'CAR Part V,' the correct answer will depend on the specific country's regulatory structure. In Canada, for example, regulations related to airworthiness are contained in the Canadian Aviation Regulations, Part V - Airworthiness, which could be indicated as 'CAR Part V.'
