What happened
During a scheduled cargo operation bound for Mexico, the aircraft experienced a significant mechanical failure involving the right-hand engine. During the flight, the propeller assembly on the right engine detached from the engine itself. As the propeller blades separated, several pieces of the hardware struck the fuselage and subsequently made contact with the left engine.
Due to the severe damage sustained by both engines and the structural integrity of the airframe, the crew was forced to execute an emergency descent. The aircraft performed a belly landing in the vicinity of Mérida. While the impact resulted in the aircraft being damaged beyond repair, there were no injuries reported among the two crew members on board.
Findings
Investigations into the mechanical failure revealed that the separation was caused by the structural failure of internal engine components. Specifically, the incident was triggered by the failure of a crankshaft and a master rod bearing within the right engine.
