AAIB investigation to Aviat A-1B Husky Pup, G-OGGY
Loss of directional control on landing, Sleap Airfield, Shropshire, 21 May 2014.
Summary:
The pilot was undergoing a tail wheel conversion training course. Runway 23 was in use at Sleap and the weather was fine, with a surface wind from 230° at 7 kt. The pilot successfully completed an exercise with his instructor, during which he flew four approaches and landings, described by the instructor as being to a high standard. The instructor then briefed the pilot to fly two solo circuits and vacated the aircraft.
The pilot described flying a normal approach and three-point touchdown but, during the ground roll, the aircraft ground looped. It yawed left through 360° before coming to a stop, during which time the right-hand wing touched the ground and was damaged.
The pilot could not explain the ground loop, which followed a normal approach and landing. His instructor suggested to him that he may have opened the throttle after landing, although the pilot had no recollection of so doing.
