Narrative:During the descent for landing in Tucumã, Brazil, there was a loss of engine power associated with high temperature (TIT) and vibration. The crew performed the "Emergency Power Lever" procedure, trying to provide power to reach the runway, but the engine continued to idle.
Due to the low height of the aircraft, a forced landing was attempted. The aircraft suffered serious but all four occupants were unharmed.
