No, the rules are about running a safe operation. I don't believe a blood alcohol level of .02 would have placed ANYONE in danger. The FAA allows commercial pilots to fly with up to .04.
I kind of doubt that pilots can fly with a .04
.04 is the legal limit for any one with a C.D.L
if you have a passenger endorsement it is .02
and if you are carrying passengers and you blow ANYTHING over .00 you are sidelined for 24 hours
