Narrative:After a short flight starting from the airfield of Cerfontaine (EBCF), the engine suddenly began to sputter and lost power. The pilot determined he could not fly back to the airfield and decided to land the plane where he could. Just before landing, the aeroplane hit the top of a tree, pitch nosed down and violently hit the ground. Location is between Dailly and Baileux.
Direct cause:
The collision of the aeroplane with the top of a tree when performing a forced landing caused by a significant loss of engine power.
Indirect cause:
- The engine loss of power was most probably caused by the internal corrosion of the carburettor which partially blocked the fuel flow at the pressure regulator valve. The corrosion of the magnesium alloy casing of the carburettor was likely caused by water contamination.
- The limited height above ground level when the engine loss power occurred and the limited maximum lift to drag ratio did not leave the pilot much time to prepare the landing.
Contributing factors:
- The schedule used for the last maintenance dated June 2016 did not require the cleaning of the fine fuel filter.
