"Scheduled 7 day stretches happened for a month or two last year, but were technically legal with the way 117 is written. Basically, if your report on day 7 is earlier than your report on day 1 by six hours, it's legal, because you only need a 30 hour rest period in the last 168 hours AT THE TIME OF REPORT. Enough of a stink was made that we never saw it again, thank God, but the company could still feasibly do it again in the future."
I heard the bwi fsdo came down hard on that interpretation. They read it as any 168 hour period independent of being legal at report. That being said there are many people scheduled with 7 day stretches here.
