Which item is listed as Category I material for mishap investigations?

• A. flight plans, weather reports, log books, maintenance records
• B. CG Foundation Grant
• C. Photographs not captioned
• D. Weather forms

Answer: (C)

In mishap investigations, Category I material refers to items that must be quickly located, preserved, and made available to investigators because they contain time-sensitive evidence essential to reconstructing what happened. Photographs from the mishap scene are a key part of that evidence, capturing conditions, damage, and actions as they occurred. However, if those photographs aren’t captioned, the context needed to interpret them is missing, which can hinder the investigation. That combination of critical evidentiary value and a need for prompt handling makes uncaptioned photographs the best fit for Category I material. The other options are either routine records or items not directly tied to the immediate evidentiary needs of the investigation, so they aren’t designated as Category I in this context.
