The aircraft was an amateur-built monoplane of composite construction powered by a two-cylinder two-stroke engine. The pilot was flying from Deanland to the PFA Rally at Kemble. The wind was light and the pilot used Runway 26 for takeoff. At about 300 feet agl, the engine ‘popped’ abruptly and then stopped completely. The pilot attempted a re-start and the engine appeared to start but then promptly stopped. At 150 feet the pilot trimmed for landing into a large field, containing a tall crop. The descent rate and approach speed into the field were reasonable but, as the wing contacted the crop, the aircraft decelerated rapidly and pitched nose down, stopping within a few metres. There was no fire and the pilot was uninjured. Both carburettor float bowls contained sediment, sufficient to restrict the supply of fuel into the engine. Larger items of sediment appeared to be small flakes of red paint, matching the fuel supply cans. The pilot noted the fuel filter element had not been fully screwed home and could therefore ‘rock’ in place. The pilot also considered that he should have refuelled through a proper external strainer to filter the fuel into the tank.
