Which PCAR part outlines the requirements for Certificates of Airworthiness?

The correct answer identifies the part of the Philippine Civil Aviation Regulations (PCAR) that deals specifically with the requirements for obtaining Certificates of Airworthiness. Part 5 of PCAR is dedicated to airworthiness standards, which govern the conditions under which aircraft must meet safety and operational standards to be considered airworthy. This part outlines critical regulations concerning the design, maintenance, and operational integrity of aircraft, ensuring they comply with safety requirements.

Understanding the significance of Certificates of Airworthiness highlights the importance of compliance with safety standards in aviation. This part effectively guides manufacturers and operators in ensuring that their aircraft are safe for flight, thereby playing a crucial role in maintaining aviation safety and preventing accidents.

The other parts mentioned do not focus specifically on the criteria and procedures for issuing Certificates of Airworthiness, which is why they are not applicable to this query. Each part of the regulations covers different aspects of civil aviation law, with only Part 5 dedicated explicitly to airworthiness.
