On 4 December 2014, directional control of an ATR 72-200 was compromised shortly after touchdown at Zurich after slightly misaligned nose wheels caused both tyres to be forced off their wheels leaving the wheel rims in direct contact with the runway surface. The Investigation found that the cause of the misalignment was the incorrect installation of a component several months earlier and the subsequent failure to identify the error. Previous examples of the same error were found and a Safety Recommendation was made that action to make the component involved less vulnerable to incorrect installation should be taken.
