.04 Mass Change Notices
When a mass change is needed, AZTECS generates an automatic notice that advises the participant of the change.
 
When a mass change results in a decrease or closure of benefits, a mass change notice must be issued no later than ten calendar days prior to the effective benefit month. (See NOAA)
 
When the reason for the action is a change in law, the notice must include a statement regarding the specific change in law.
 
FAA may also publicize mass changes through the news media and posters in local offices and other public places.
