Just as I was leaving a large Irish airline, they were in the process of banning switching off Flight Directors unless required by SOPs on a Non-Precision or Visual approach.
This was in response to a number of incidents from a small group of pilots in one particular base. Unfortunately these were all seriously unstable approaches leading from switching everything off above 10k in marginal weather. As I haven't worked there for a while, I don't know how things are these days.
