That all depends if the information has been disseminated all the way down the food chain so to speak in the airline concerned.
Who fitted the pin, what level of competency/training they have and which way it was inserted(from the left or from the right)also has a bearing on the outcome due to the differing diameters of the offending hole.
The FAA AD and it's subsequent rectification was raised because it is a known issue.
Not all airlines have embodied the mod yet.
You might like to read up on the EVA B744 nose leg collapse at LHR or a similar occurrence which happened to Lufthansa at FRA.
The nose gear pin was fitted in the correct location in both those incidents.
Also, the B747-100 incident at BAMC where HF came into play big time and resulted in the main body gear partially collapsing.
However before the gear checks began, the U/C pins had been checked by an experienced engineer.
