AAIB investigation to Bombardier BD700-1A10, CS-GLD
Right wing tip touched the runway on landing, Biggin Hill Airport, Kent, 17 September 2020.
Summary:
The aircraft was on a positioning flight from Edinburgh Airport to Biggin Hill Airport in Kent and, having completed a circle-to-land procedure, carried out the final approach to land. The aircraft was fully configured for landing, established at the approach airspeed of VREF with the autothrottle engaged but being ‘hand flown’ by the pilot. There was a crosswind component from the right.
During the flare, a large amount of right rudder and right roll control was applied with the aircraft in a high nose-up attitude, causing a roll to the right. Although the roll was countered immediately with a large application of opposite roll control, the aircraft touched down before this input took effect, and the combination of nose-up pitch attitude and right wing down caused the wingtip to contact the runway.
The landing technique just before touchdown was not in accordance with the manufacturer’s crosswind landing technique. However, a simulation by the manufacturer showed that the roll rate achieved was not accounted for by roll control alone, and it appeared likely that it was increased by localized wind or gust effects.
