The flight approached Batagay (situated in mountainous area) at night. The crew decided to use a track that is allowed only for visual approaches. Intentional deviation from the approved procedure caused the GPWS to sound. The GPWS was switched off and the An-12 eventually collided with a mountain at 537 metres above the runway level.
