Mike, not relevant eh? You know, 76% of light aircraft crashes in the US are down to alcohol. But at any rate, no fatalities attributed to alcohol in the UK on aircraft under parts 23 and 25.. what does that say? No need for the legislation since we all got by nicely without it, or sheer luck?
Considering the high percentage of pilot error involved in fatal aircraft accidents, and considering the propensity of alcohol abuse by British pilots (goes hand in hand with the thrill seeking nature of being a pilot), I would find it incredibly hard to believe that alcohol never once played a part in a fatality in the UK (commercial ops of course).
In any event, the very belief that no accidents have occurred yet in the UK as a result of alcohol consumption is neither here nor there. They have happened elsewhere.
HD's citation of his AME says it all. And with that in mind, it takes a HEALTHY liver an hour to process a unit.
And whatever happened to adhering to the ANO section 1 part 5 article 65 para 1? Seems to be a very funny attitude towards alcohol in this industry.
Furthermore it is very clearly stated in Finnish law that only a zero blood-alcohol level is tolerated whilst acting as a crew member. See Ilmailulaki 1995/281 38 §, paragraph 1, "Tehtävää ilma-aluksessa ei saa suorittaa se, jonka veren alkoholipitoisuus on alkoholin nauttimisesta kohonnut tai joka on käyttänyt muuta huumaavaa ainetta niin, että sitä on hänen elimistössään havaittava määrä."
