Circumstances:
While cruising at an altitude of 1,300 meters en route to Kramatorsk, Ukraine, the left engine failed. Shortly later, the right engine overheated and lost power. In such situation, the pilot attempted to make an emergency landing when the aircraft crash landed onto a hillside. All five occupants were unhurt while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the failure of the left engine was caused by the failure of the intake valve, resulting to the rupture of the second cylinder. The ignition system also failed, which contributed to the engine failure.
