Who issues a JAR 66 certifying staff license?

The correct answer is that a JAR 66 certifying staff license is issued by the National Aviation Authority (NAA). The NAA is the official regulatory body within a specific country responsible for overseeing all aspects of civil aviation, including the certification of personnel involved in maintenance and airworthiness of aircraft.

The framework defined by JAR 66 (Joint Aviation Requirements) established requirements for the certification of maintenance personnel in Europe, and it is the NAA that has the authority to issue licenses to qualified individuals who have met the required training and examination standards. This ensures that all certifying staff are adequately trained and competent to maintain aircraft safety and airworthiness.

The other options, while related to aviation and regulatory authorities, do not have the authority to issue the JAR 66 certification. The head office of the JAA (Joint Aviation Authorities) and its local offices provide guidance and oversight but do not issue licenses directly. The CAAP (Civil Aviation Authority of the Philippines) is a specific national authority, which could issue certifications but within the jurisdiction of its own regulations, not under the JAR framework in general. Thus, the NAA is the correct authority for issuing the JAR 66 certifying staff license.
