Incident Overview
Description
Viscount G-ALWE (the first Viscount 701 type to be manufactured) approached Manchester-Ringway Airport following a flight from Amsterdam. After a GCA (Ground Control Approach) approach, the aircraft broke through the lowest clouds and the crew continued the approach visually. The approach was uneventful until it was about 1 mile short of the runway. The aircraft was seen to enter a shallow right descending turn with a steepening bank angle. The right wingtip touched the ground and the aircraft crashed into houses 85 yards further on. It appeared that the aileron became locked when the no. 2 flap unit of the starboard wing moved away from the trailing edge member following failure of a lug and bolt of the flap fitting. PROBABLE CAUSE: “The fracture, due to fatigue, of he 9/16 inch bolt holding the bottom of the No2 starboard flap unit.”
