During an otherwise normal landing at Cardiff, a failure in the right landing gear freed the axle to oscillate about a vertical axis, leading to severe damage and deflation of both tyres. The original failure was the result of the corrosion induced weakening of a threaded attachment. Consequent overload fracture of another component appears to have taken place before the Cardiff landing. The landing gear manufacturer is introducing a new Service Bulletin to address the deterioration of the corroded and failed area in service and amending the build procedure to obviate the possibility of surface damage during component assembly creating an origin for a corrosion process. A further problem noted during the fleet inspection following the original event has been addressed in the final Service Bulletin.
