The Islander had operated on an ambulance flight to Inverness and was ferried back to its base at Tingwall Airport. The pilot manoeuvred the airplane for an approach to runway 02. While turning to finals the aircraft was blown through the centerline, forcing the pilot to abandon the approach. He climbed to 550 feet and positioned the airplane for another approach. For this second attempt the pilot extended the downwind leg by approximately 800 metres before turning towards the airfield. A rapid turn to finals with a steep bank angle was performed during which the aircraft descended. In a right wing low attitude of some 70øand a nose low attitude of approximately 20ø the aircraft collided with grass covered gently rising terrain, 1,5 km South of the runway. Its groundspeed at this time was estimated at 125 kt. The investigation report did not contain a ‘probable cause’.
