Crew Member Self Defense Training (CMSDT) Program, July 24, 2013 (PDF, 8 pages, 153 KB). TSA’S CMSDT Program is a voluntary self-defense training course for U.S. commercial and cargo air carrier crew members. The program trains crew members on how to defend the flight deck against acts of criminal violence or air piracy. TSA previously published a PIA on this program on February 6, 2008. TSA has collected CMSDT Program information principally through completion of an electronic registration form hosted on the TSA.gov web site. At times, information was collected through paper forms. TSA has updated the PIA to reflect that it will: (1) collect information from crew members solely through electronic means; and (2) conduct personnel security suitability checks on American Association of Community College Site Coordinators so that they may be granted access to an existing secure TSA web-based system in order to process registrations on behalf of crew members.
