The pilot was unable to restore the fuel supply to the engine and landed the aircraft in a field but impacted a fence and hedge. The pilot was uninjured. The UK CAA advised that a Service Bulletin relating to the failure of the fuel selector lever is to be issued. History of the flight The aircraft is equipped with two fuel tanks which are selected within the cockpit by a three position lever. The intermediate lever position is fuel off. Whilst routing within the northern boundary of the Yeovilton MATZ at a height of about 500 ft, the pilot tried to select the left fuel tank, but as he moved the selector lever from the right tank, through the fuel off position, the lever detached from the valve assembly. The pilot attempted to reattach the lever and also move the valve with his fingers, but he was unsuccessful and the engine stopped several seconds later. At this time Yeovilton ATC contacted the pilot and he declared a PAN, whilst also positioning the aircraft to land in a field ahead. Shortly after, the pilot realised that he would not make the selected field and repositioned to land downwind in a field to his left. The aircraft landed longer than expected and struck a fence and hedge before coming to a stop. The pilot was restrained by a full safety harness and exited the aircraft normally. The pilot stated that in hindsight, he had been distracted from concentrating on the forced landing when responding to ATC. 42© Crown copyright 2012 11/2012 AAIB Bulletin: G-EECC EW/G2012/07/07 The UK CAA advised that a Service Bulletin relating to the failure of the fuel selector lever is to be issued.
