Does a commander have the authority to remove a senior member from active status if they are not completing training or participating in any squadron activities?

Unlike cadets, there is no specific requirement for senior members to regularly attend meetings or progress in rank. However, there are provisions for commanders to initiate membership termination or transfer procedures for senior members for habitual failure to complete training requirements, perform duty requirements and for substandard performance of duty over an extended period of time. Commanders might also remove a person from a duty position in the unit for these same reasons. Another possibility for the member who does not complete required training or participate on a regular basis is for the commander to transfer the member from "Active Status" to "Reserve/Patron Status."
