TDK mk2 Rather flippant response. If you are serious I would explain it thus: "Fatal" in the sense of permanent loss of certificate. "Zero tolerance"? In this case, yes.
I would recommend all who are convicted appeal the conviction if so disposed. If convicted of impairment, and there are unknown circumstances "to overturn the conviction", be heard, by all means. There are thousands of jobs available to skilled pilots other than piloting, if alcohol is a problem. If it is a problem, seek help, I could help you find a way out. Don't make it the Public's problem or pilots at large, please.
