Accident Details
A single-engine aircraft departed a remote area located 250 km west of Tura, carrying five passengers and two pilots who were returning from a fishing camp. Shortly after takeoff, at a height of one meter, the engine began to vibrate and the crew noticed a 'pop' noise. The airplane descended and the crew positioned the flaps to 40°. The aircraft passed over a river then impacted the opposite bank and crashed. The aircraft was damaged beyond repair.
Occupants and Injuries
All seven occupants evacuated safely, except the pilot who was slightly injured. The nature of the pilot's injury was not further specified.
Probable Cause
According to the official investigation, the probable cause was failure of the exhaust manifold tube due to fatigue cracks, which caused a loss of engine power after hot gases went through the carburetor that was open at 30%.
