A firefighting Kamov Ka-32S crashed under unknown circumstances in Çardak district, Denizli province.
Two occupants died in the crash and five were injured. The helicopter was destroyed.

The aviation accident involving the Ka-32S helicopter with registration RA-31591 occurred during an emergency landing, necessitated by the auto-shutdown (engine stoppage) of both engines in flight due to complete fuel exhaustion. The contributing factors, most likely, were as follows:
- Failure of the crew to initially plan for an intermediate landing to refuel;
- Errors by the crew in calculating the required amount of fuel for the flight, associated with not accounting for increased fuel consumption during terrain-following flight instead of flying at a constant altitude;
- Failure to make a decision to select a landing site and perform an emergency landing upon activation of the low fuel warning, followed by the self-shutdown of one of the engines;
- Unjustified selection of the flight mode (altitude, speed), practically excluding a safe transition to autorotation mode in the event of engine failure;
- Individual-psychological characteristics of the captain, who made decisions and actively piloted during the final stage of the flight, characterized by a lack of criticality and disregard for the risks that, in emergency flight conditions, led to unjustified (risky) decisions taken contrary to the provisions of the flight manual.
