The pilot reported that he had flown from RAF Weston-on-the-Green for the short flight to South Cerney. Runway 24 was in use; it was a grass runway, some 920 m in length and described as wet. The weather was good, with a surface wind from 240ø at 5 kt and the temperature was 16§C. The pilot reported that he landed long and that, when applied, the brakes locked. The aircraft slid along the runway, before over-running the end and passing through the perimeter fence, causing damage to the nosewheel, propeller and wing leading edges. The pilot reported that he sustained minor injuries. In his brief report, the pilot did not offer any information about the type of approach, aircraft configuration, the decision to continue the approach or why the aircraft may have landed long (a photograph of the accident scene showed the wing flaps apparently only partially extended). Thus, the circumstances of the accident and possible causes remain unclear Nature of Damage sustained to airframe: Per the AAIB report “Damage to the nosewheel, propeller and leading edges of both wings”.
