Narrative:A Cessna 208B Grand Caravan was destroyed in a forced landing in a rocky river bed near Tayoltita, San Dimas, Durango, Mexico. Three passengers were killed.
The aircraft operated on a flight from Tayoltita to Durango in Mexico and took off about 09:00 hours local time. About fifteen minutes into the flight, as the aircraft was climbing to 9500 feet, the pilot hear a strange noise from the engine.
