What law governs the practice of aeronautical engineering in the Philippines?

The practice of aeronautical engineering in the Philippines is governed by Presidential Decree No. 1570. This law establishes the framework for the regulation and professionalization of engineering practices within the country, specifically addressing the qualifications and licensing of engineers in various disciplines, including aeronautical engineering. PD 1570 mandates the creation of rules and regulations by the Professional Regulation Commission (PRC), which is responsible for licensing and regulating engineering professionals.

In this context, while the Civil Aviation Regulations play a significant role in the aviation sector by outlining standards and requirements for safety and operational procedures, they do not specifically govern the practice of aeronautical engineering in terms of professional qualifications and regulations. RA 9497, on the other hand, pertains to the establishment of an authority for civil aviation, but it is not directly related to the licensing and practice of aeronautical engineers. Therefore, PD 1570 stands out as the correct law governing it.
