British final report from incident in January, Global Express N618WF The aircraft was on final approach to Runway 26 at Luton Airport with the autopilot engaged. At about 210 ft above the touchdown zone, the aircraft suffered a disturbance probably due to a gust of wind.
The autopilot was disengaged below a radio altitude of 10 ft but there was insufficient time for the pilot to prevent the left wingtip hitting the runway, marginally before the left landing gear. It was possible that the unusually high rate of decrease of radar altitude, a feature of the approach to this runway, contributed to the late disconnection of the autopilot.
