| Executive Summary: | The accident occurred when the aircraft, which was on a scheduled flight from Southampton to Guernsey, overran Runway 27 whilst landing on a wet runway in strong crosswind conditions. Both propellers were reportedly selected to ground fine pitch after touchdown. The commander was not aware that the crosswind component at the time of landing was 34 kt, which was 5 kt above the maximum allowed by the company operations manual. Consequently he had difficulty in maintaining directional control whilst attempting to apply maximum braking. The two pilots and two of the passengers sustained minor injuries as a result of the overrun and subsequent evacuation. The remaining passengers were uninjured. The aircraft sustained substantial damage to the landing gear, the right wing, right engine and propeller. The investigation identified the following causal factors: (i) The commander decided to continue with the landing knowing that touchdown was beyond the normal point. (ii) The commander was not aware at touchdown that the crosswind component of the surface wind affecting the aircraft exceeded the Flight Manual limit. (iii) The commander could not apply maximum braking to both main landing gear brakes at the same time as maintaining directional control through differential braking and full rudder application. One safety recommendation was made during the course of the investigation. |
