The accident investigation by the Peruvian Comisión De Investigación De Accidentes De Aviación (Aviation Accidents Investigation Commission) established that while the aircraft was cruising at an altitude of 700 meters , a luggage net that was improperly placed in a rear fuselage compartment became entangled with the tail rotor's transmission shaft and control cables, causing the cables to snap and resulting in a total loss of directional control.
