When applying full power, following a descent at idle power there was a sudden bang and heavy vibration. The vibration eased on reducing power but increased again as power was applied. The pilot declared a MAYDAY and initiated a forced landing. At 50 ft, the pilot realised that his selected field was unsuitable so he veered left and landed in a harrowed field. The wheels dug in and the aircraft flipped inverted. The cause of the engine problem could not be determined.
