I think (but not sure) that Renslow slept in the crew room...I'm sure that was quality rest.

The FO definitely spent all night commuting on multiple legs to start a day shift which ended with a fatal crash late that evening. She failed to do the right things (backup the CA and take control when he failed catastrophically) and she did do about the worst thing she could have: raised the flaps in a stall.

Would the new rules have prevented the crash? Hard to say. But it's easy to see why some people think we need the rule in light of circumstances surrounding that accident.

The problem is that the rules does not allow for a reasonable commute without impacting duty time...and is absolutely inconsistent given that it singles out pilots who commute by air, without accounting for the guy who rides his motorcycle three hours in freezing weather to save gas (yes I know this guy, he arrives 30 minutes early to warm up before check-in). Or the guy who stays up all night and parties.

If pilots are not to be trusted, then make it consistent...all pilots check into a company rest facility at the airport (private sleeping rooms) ten hours prior to block out...and get paid block the whole time of course.

The million dollar question is how are airlines going to deal with this? Will they allow you to eat into your max duty as long as you leave a couple hours padding above your scheduled duty? Or will they require you to always be available for the full legal duty period from scheduled check-in? That would essentially forbid commuting. In that case I would probably ignore the rule until I got caught, then find a new job.
