Which authority is responsible for organizing an Aircraft Accidents Investigation and Inquiry Board?

The correct authority responsible for organizing an Aircraft Accidents Investigation and Inquiry Board is the Civil Aviation Authority of the Philippines (CAAP). This agency is tasked with ensuring the safety and security of civil aviation in the Philippines, which includes investigating aircraft accidents and incidents to determine the causes and prevent future occurrences.

The CAAP conducts comprehensive investigations that often involve gathering evidence, analyzing data, and collaborating with various stakeholders to enhance aviation safety. Their role is critical in maintaining the integrity of air travel and ensuring compliance with international aviation standards.

In contrast, the other entities listed have different functions. The CAB, or the Civil Aeronautics Board, focuses on regulatory and economic aspects of aviation, such as airline routes and fares. The DOTC (Department of Transportation and Communications) is responsible for overseeing transportation policy and regulatory frameworks, while the Air Operator typically focuses on the operational aspects of providing air services rather than conducting investigations. Therefore, the designation of responsibility for accident investigation firmly rests with CAAP, making it the correct answer.
