The safety statistics might indicate that there are many more events on a range of aircraft due to NWS problems than would be expected; IIRC a CAST group investigated the maintenance aspects re runway excursion (off the side).
Many years ago the BAe146/Avro RJ suffered a spate of incidents, but diligent safety investigation by both the gear manufacturer and BAe identified contributory issues, many as above.
The 146 problems generally occurred during landing, but with a temporary procedure of checking the NWS tiller position after lowering the gear the hazard could be contained – centre the tiller.
Even so these manufacturers did not write the problems off to statistics, they took action.
IIRC, set-up / maintenance changes cured the problem.
