AAIB investigation to Yakovlev YAK C11, G-OYAK
Total loss of engine power, field near Little Gransden Airfield, Cambridgeshire, 21 June 2018.
Summary:
The engine started to misfire as the pilot joined the downwind leg at Little Gransden Airfield for a landing on Runway 28. The pilot flew a tighter circuit, but late during the final approach the engine lost power. As the aircraft could no longer reach the runway, the pilot made a successful wheels-up landing and the aircraft touched down 150 m short of the runway threshold. The loss of engine power was most probably due to the magneto coils starting to break down.
