Beechcraft 58TC Baron, N6751W
The pilot reported that the cloudbase was broken at 1,000 ft, so he conducted a visual “bad weather” circuit, to land on Runway 29. As the aircraft touched down, the pilot realised it had landed both deeper into the grass runway, which was wet from recent rain, and faster than normal. After applying the brakes he “did not notice good retardation”. A go-around was considered but being uncertain of its success, the pilot elected to remain on the runway.
The aircraft overran the runway and entered an adjacent field at low speed. In the process, it encountered a mound and ditch, which caused significant damage.
The pilot had considered the aircraft’s landing performance, applying a factor of 1.3, and recalled that, touching down at the appropriate point on the runway, there would be about 200 metres to spare. He commented that an earlier decision to go-around would have prevented the accident.
The CAA’s Safety Sense Leaflet 7c, ‘Aeroplane Performance’, provides guidance on performance planning and the factors to consider for take-offs and landings. It advises that very short wet grass on a firm soil base may be slippery, adding up to 60% to the landing distance required.
