The aircraft departed with full fuel tanks and had been airborne for approximately 25 minutes when the engine lost power. The pilot sustained back injuries in the subsequent forced landing. The investigation revealed that a threaded union which connected a drain line to the bottom of the carburettor fuel bowl had unwound, causing the bowl to drain. The engine then lost power due to fuel starvation.
