Depends. Personally, I wouldn't release the aircraft without knowing what was causing the vibration. But if the vibration was corrected by the engineers, i.e., no vibration felt prior to this flight, then one would assume the disc was fixed. Until we know this part, it will remain a guessing game. Some seemingly routine discrepancies end up leading to unforeseen failures, like in one case where a random xsmn chip light led to the loss of the upper xsmn case and rotor system in flight. No one saw that coming either.
