Executive Summary:Following selection of landing gear down during an approach to Runway 26L at Gatwick Airport, the nose landing gear indicator displayed a red unsafe indication. The main landing gears both showed green 'down-and-locked' indications. At 2,000 ft and 160 kt the landing gear was cycled again; the nose gear indicator continued to show red, with the two main gear indications showing green. A fly past of the Control Tower was made, during which it was visually confirmed that the nose gear was retracted, with both mains extended. Despite further cycling of the landing gear, the nose gear failed to extend. The emergency landing gear extension system was therefore activated, and the landing gear then extended fully with three greens being displayed. However, during the subsequent landing roll, following an uneventful approach and touchdown, the main landing gear doors were damaged by contact with the runway surface, and associated debris was ingested by the N 2 engine causing minor damage.
