Nature Air Flight 144 crashed into terrain on 31 December 2017 shortly after takeoff from Punta Islita Airport in Nandayure, Guanacaste Province, Costa Rica, for a chartered domestic passenger flight to Costa Rica's capital San José killing all 12 people on board. The flight, with a planned duration of 40 minutes, was operated by Costa Rican regional airline Nature Air and the aircraft involved was a Cessna 208B Caravan manufactured in 2001. On board the aircraft were 10 passengers, mostly American tourists, and 2 pilots. An NTSB investigation later determined that the accident was caused by the aircraft entering an aerodynamic spin/stall that was the result of pilot error. Nature Air permanently ceased operations following the accident.
