Narrative:

Approximately early afternoon; august 2014. I (as maintenance controller X) received verbal information from the assistant chief pilot (acp) on duty that a dassault falcon 2000 had landed at ZZZ1 and had a situation with their nose landing gear (nlg) wheels. He informed me that they had stopped the aircraft on the taxiway; removed the passengers; and were having the aircraft towed to the ramp. Approximately 15 minutes later I received a call from the PIC of the aircraft and he explained what had transpired. He said that they had a normal and uneventful landing and while taxiing back to the ramp; they heard a grinding/vibration type sound coming from the nose gear area of the aircraft. They informed the tower that they were going to stop on the ramp; exit the aircraft; and investigate. He said that he exited the aircraft and from what he could see the nlg wheels/tires and vicinity looked normal. He returned to the aircraft discussed the situation with his co-captain and they continued their taxi to the ramp. Immediately after attempting to taxi for the second time they received a call from the tower informing them that they had what seemed to be smoke coming from the nlg area. They immediately stopped the aircraft; removed the passengers and had the aircraft towed the remaining way to the ramp. Once on the ramp and after closer inspection; the captain noticed that it looked as if the outer wheel bearing on the left-hand (lh) side nlg wheel assembly was missing. Maintenance control researched for any maintenance that had previously been accomplished to the nlg components and found that both nlg wheel assemblies had been replaced three days earlier. The aircraft had operated for three days and flown seven cycles since the wheels were installed. The aircraft was immediately taken out of service and a repair plan initiated. No recommendations at this time; pending causal findings. Nose landing gear wheel assembly bearing failure.
