Détails:
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.
The engine lost power and the speed dropped. The pilot then prepared for a forced landing in a river. The left wing hit a tree and the aircraft then impacted very large stones in the bed of the river, causing the aircraft to split two.

Probable Cause:

PROBABLE CAUSE (translated from Spanish):
Loss of engine power, due to fatigue fracture of a turbine compressor disc blade (CT blade), resulting in an emergency landing.
Contributing Factors:
1. Compressor turbine vane ring rework without the authorization of the engine manufacturer and subsequent installation in the overhaul to the engine.
