Incident
A crew was conducting a mosquito spraying mission in the region of Jagodina. After a 50-minute successful operation, the engine began to vibrate, smoke emanated, and an oil leak occurred. The crew decided to divert to the nearest airport.
Emergency Landing
As the aircraft proceeded towards the diversion airport, oil spread onto the windshield, causing the crew to lose all visual contact with the ground. They attempted an emergency landing, during which the aircraft's left wing struck a tree. The aircraft subsequently crashed in a field.
Aftermath
All three occupants evacuated the aircraft uninjured. The aircraft sustained damage beyond repair.
Probable Cause
The official investigation found the immediate cause of the accident to be engine failure due to the breakage of the connecting rod of the 6th cylinder, which caused breakages in the 1st cylinder and further damage to the engine. An indirect cause was a hydro shock the engine experienced during a previous cold start.
