Which task is NOT a responsibility of the MFA?

The task that is not a responsibility of the MFA, or Mission Flight Assistant, is performing aircraft maintenance checks. The MFA's role primarily focuses on supporting the flight crew and managing mission-related activities on board the aircraft, such as coordinating cargo load briefings and executing emergency procedures. While safety is a priority, the MFA is not typically involved in the technical aspects of aircraft maintenance, which are generally handled by licensed maintenance personnel and certified technicians. By understanding this distinction, one can see that the MFA operates in a capacity that supports flight operations without delving into the mechanical maintenance of the aircraft itself.
