Which investigation involves potential civil aircraft or FAA personnel?

Interagency Investigation is centered on collaborative efforts among various governmental and regulatory entities, such as the Federal Aviation Administration (FAA), to look into matters that may involve civil aviation and personnel associated with it. These investigations aim to address incidents requiring input from multiple agencies, facilitating a comprehensive analysis that incorporates a range of expertise.

In this context, the focus on potential civil aircraft or FAA personnel is particularly pertinent. It underscores the collaborative nature required when incidents or anomalies occur that may impact airworthiness or involve regulatory compliance. The investigation utilizes knowledge from various aviation safety and regulatory domains, aiming to enhance overall air safety standards.

The other investigation types listed do not primarily focus on civil aircraft and FAA personnel. For instance, the Field Naval Aviator Evaluation pertains to military evaluations, not civil aviation. The Aviation Mishap Safety Investigation mainly deals with mishaps and safety techniques without indicating involvement of FAA personnel specifically. Class D Mishap Investigation is similarly structured around internal assessments rather than interagency collaboration, placing emphasis on potential military operations instead of civilian regulations and oversight. Thus, the correct choice reflects the intersection of interests regarding civil aviation and regulatory personnel, highlighting the importance of a broad-based evaluation in such circumstances.
