It would appear that Airbus have this matter now under control.
Jet Blue A320 Nose Landing Gear Incident at LAX
"The investigation into the Jet Blue event will be clearly focused on the Nose Landing Gear. Whilst it is premature to draw any conclusions concerning this event; two incidents have previously been reported where a landing was carried out with the nose landing gear (NLG) wheels at 90 degrees to the aircraft centerline. Both events occurred a few days after a NLG shock absorber dynamic seal replacement.
The checks performed after the events revealed an incorrect installation of the NLG shock absorber in the NLG leg. The upper cam was rotated from its original position by one dowel creating an offset of 20 to 30 degrees. Therefore, the lugs of the piston of the shock absorber were not properly engaged by maintenance into the slots of the shock absorber backplate, to compensate the cam offset.
On landing, the NLG tyres quickly deflated and were torn apart. Both wheels were worn away up to the wheel axle.
Maintenance Manual procedures have been amended adding additional steps to ensure correct cam alignment.
Airbus has reviewed the NLG shock absorber backplate design and has introduced a full proof device (modified upper support) which aims to avoid the possibility of errors in maintenance installation".
