Delivered to the USAF as C-130A with serial 57-518, struck off charge in May 1976 and put into storage at the AMARC facility in Tucson (AZ). After a number of years in storage the Hercules became N9691N in March 1987 with the Military Aircraft Restauration Corp whom later sold the aircraft to AeroPostal Cargo de México in August 1993. Based at Mexico City the C-130 joined another Hercules (XA-RSH) of the same company until both were withdrawn from use at their homebase.
