A Let L-410 aircraft operated by South Sudan Supreme Airlines crashed shortly after departure from Pieri Airstrip, South Sudan. All ten on board, two pilots and eight passengers, have reportedly died. The aircraft operated on a flight to Yuai and Juba.
The Jonlei State Government stated the aircraft involved was registered "HK-4274".
HK-4274 matches the registration of a Colombian Agusta-Bell AB-205A helicopter. This helicopter was sold and this Colombian registration mark is no longer in use. It was used as a fake registration on a Let L-410.

The South Sudan Civil Aviation Authority reported that one of the aircraft's engines failed about ten minutes after takeoff. While turning back to Pieri the second engine is also reported to have failed.
