Narrative:
An Aer Caribe Antonov An-32 cargo plane suffered a runway excursion after landing on runway 06 at Iquitos Airport, Peru.
Upon touchdown, the crew proceeded to disconnect the propeller stops to use reverse power as a braking measure. However, the aircraft veered sharply to the left, off the side of the runway.
The aircraft crossed an area of vegetation and a drainage channel, suffering severe structural damage including breakage and separation of the right wing, the main landing gear and the right engine; in addition, there was a fuel spill which caused a fire on the wing.
The airport emergency services managed to control the fire and evacuate the crew and passenger on board.


PROBABLE CAUSE
Runway Excursion due to loss of directional control of the aircraft after landing by disengaging the propeller stops for aerodynamic braking at a higher than established speed, which generated an uncontrollable leftward turning moment of the trajectory, due to asymmetric thrust of the propellers.

CONTRIBUTING FACTORS
1. Performing a landing on an Unstabilised Approach, not executing the established Go-Around procedure.
2. Performing a failed landing due to asymmetric thrust of the propellers, not applying the procedure established in the Operator's QRH to shut down the failed engine.
3. Probable failure of the KTA Fuel Regulator of the Automatic Engine Rotation Frequency and Power Regulation System, which blocked the reduction of the power of the N°2 engine to established operating regimes for the approach and landing.
