Which regulation defines the requirements for aircraft types brought under Philippine registry?

The regulation that defines the requirements for aircraft types brought under Philippine registry relates specifically to the certification and operation of the aircraft, along with ensuring compliance with established safety standards. In this context, 14 CFR 21.183 is the correct reference, as it outlines the requirements for type certification of aircraft within the U.S. Federal Aviation Administration (FAA) jurisdiction, which is closely mirrored in various international regulations, including those in the Philippines.

Type certification is a critical step that ensures an aircraft model meets specific airworthiness and safety standards before it can be registered and operated. Regulations in different jurisdictions often align with or reference similar standards to maintain safety and interoperability among aircraft internationally.

While other options refer to different aspects of regulations (for instance, operational rules or specific conditions under which pilots operate aircraft), they do not specifically address the type certification necessary for registering an aircraft in the Philippines. This distinction is crucial as it ensures that any aircraft operating under Philippine jurisdiction meets the rigorous safety and performance requirements established by the aviation authority.
