Perhaps Concorde, although I don't know if the emergency grounding was mandated by the authority or voluntary.

As I recall one of the problems with the Concorde was that the existing fleet was getting quite old and spare parts were hard, if not impossible to come by.

The incident in Paris may have sped up the process of decomissioning the plane, but it would have happened anyway eventually.

All was not lost. A lot of the more visionary aspects of that plane, were implented into later Airbus models (i.e. the glass cockpit derives directly from the Concorde).
