On December 1, 2011, about 2048 UTC, a Cessna TU206G, Peruvian registration OB-1299, registered to and operated by Palmas del Espino S.A., collided with mountainous terrain near Cerro Escalera, Peru. Weather conditions at the altitude, location, and time of the occurrence are unknown, and a visual flight rules (VFR) flight plan was filed for the foreign, non commercial passenger flight from Shanusi Airport, San Martin, Peru, to Aeropuerto Guillermo del Castillo Paredes Airport (SPST), San Martin, Peru. The airplane sustained substantial damage and the certificated commercial Peruvian pilot and three passengers were killed. The flight originated about 2030 UTC from Shanusi Airport. After reporting to the control tower while flying over Cerro Escalera, the pilot was told to orbit to the west. Radio contact was lost immediately afterwards. The airplane impacted mountainous terrain about 4,250 feet above sea level on the west side of Cerro Escalera which has an elevation about 4,500 feet above sea level.
