Lets try again so you don't get busted....you're actually violating the "look back" part of the reg in that you haven't had 10 consecutive hours of rest in the last 24 hours upon completion of your duty period. 135.267(d) doesn't contain an explicit duty time limitation BUT crewmember MUST meet the rest requirements of 135.267(d). You'll notice the only allowance for anything to be exceeded "beyond the control of the operator" in all of 135.267 is ONLY flight time.
Even though your POI may be in agreement with you violating a rule, you won't have to answer to your POI when something happens, you will have to answer to an ALJ or the Board...your POI will also have to answer to them as well (at least you won't be alone). Again, there's a legal interpretation from the FAA's General Council that specifically talks about this. Just because you've been doing it this way for 17 years doesn't mean it's correct. Be careful, your hanging yourself out there.
Can you post the legal interpretation? I'd like to read that, perhaps I have had it wrong all these years.
