Circumstances:
The 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 started to vibrate and the crew noticed a 'pop' noise. The airplane descended and the crew positioned the flaps to 40°. The aircraft passed over the river then impacted the opposite bank and crashed. All seven occupants evacuated safely, except the pilot who was slightly injured. The aircraft was damaged beyond repair.
Probable cause:
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%.
