On final approach to Netherthorpe’s Runway 24 the pilot reported experiencing a ‘huge lump of turbulence’ that caused his aircraft to roll left to approximately 45? of bank. He rolled the wings level and now a little low on the approach he also applied some power. As the aircraft crossed the runway threshold the aircraft experienced more turbulence and sank. The pilot applied full power but it was insufficient to arrest the high rate of descent resulting in a heavy landing that caused the left main landing gear leg to collapse. The engine continued to run with no damage to the propeller but the aircraft came to rest quickly. The pilot and his passenger were able to exit the aircraft unassisted. The pilot described the weather as ‘thermic’ because during their flight they had experienced many updrafts and downdrafts. The turbulence and sudden left roll experienced by G MYMI during the approach was, therefore, probably caused by a thermal induced updraft or downdraft. The high sink rate and heavy landing were probably a result of a loss of airspeed, possibly aggravated by the turbulent conditions.
