Which regulation in the Philippines abolished the Air Transportation Office and established CAAP?

The regulation that abolished the Air Transportation Office and established the Civil Aviation Authority of the Philippines (CAAP) is Republic Act 9497. This law was enacted to enhance the regulatory framework for civil aviation in the Philippines, transitioning from the previous regulatory body to CAAP, which is tasked with ensuring safe and efficient air travel within the country. By establishing CAAP, the act aimed to improve the organization's capability to regulate and oversee the safety and standards of civil aviation while aligning with international aviation standards. The establishment of CAAP also included provisions for the modernization of the country's civil aviation system, which reflects the need for improved management and regulation in response to the growing demands of air travel. Other options, while they may relate to aviation or transportation, do not pertain specifically to the establishment of CAAP or the abolition of the Air Transportation Office.
