Two Y12 aircraft were donated by China to the Colombian Government. in 2014 they were assigned to Satena, the passenger airline run by the Air Force, to keep connections to remote locations in the country. For several years the two were based at Medellin Olaya Herrera, flying to destinations in Northern Antioquia and Choco provinces. It is unbelievable that after only 5 years the airplanes reached their max lifetime hours or cycles and were withdrawn from use.
