Which term describes a member who may join the SIB under specific conditions?

• A. Conditional Member
• B. Primary Member
• C. Observers
• D. Secondary Member

Answer: (A)

In this context, membership can be defined by how and when a person is allowed to participate in the Safety Investigation Board. When someone may join only under certain conditions, that status is described as conditional membership. This allows the board to bring in needed expertise or involvement for a specific investigation without making the person a permanent or full voting member. The other roles imply permanent or broader involvement: a primary member is a full member, with complete participation and voting rights; a secondary member usually has a more limited, ongoing role; observers can attend to learn but typically do not become part of the decision-making process. So the term that fits “may join under specific conditions” is conditional member.
