AAIB investigation to Yakovlev YAK C11, G-OYAK

Total loss of engine power, field near Little Gransden Airfield, Cambridgeshire, 21 June 2018.


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.
