Narrative:
The aircraft was on approach to Runway 26L at London Gatwick Airport and was being configured to land. After flaps 1 was selected, there was a progressive deterioration in normal flight controls, landing gear lowering and nosewheel steering capabilities. The crew performed a go-around and actioned the relevant checklists. The aircraft landed safely with flaps 20 set but with the nosewheel steering inoperative.
The cause of the system degradation was a failure of the Nose Landing Gear Isolation Valve (NLGIV). Following this event, the manufacturer changed its procedures in relation to the manufacturing and testing of the NLGIV.
