Am I legal to fly a four man crew 12+hr block
 

I flew a 3 man crew,
then a 4 man crew,
then four 2man crews at 20 + hours,
then a 3 man crew again.

I would belive that 121.525 a and c would apply. this refers to 121.521 (a) which limits me to a 12hr scheduled flight time in 24hours. My scheduled trip is over 12 hours block in 24. How can this be legal if I fall under 121.521 (A)!!! Which limit me to 12hrs

My flights
3 man
4 man
2 man x four flights totalling more than 20 hours
3 man

Now I am scheduled to fly a 4 man flight that blocks MORE than 12 hours!!. 121.525 a and c refer to 121.521 a which limits flight time to 12 hours.

What am I missing??

Please reply soon, I need help this.

121.525 a refers to Flight Deck Duty (which is different than Scheduled Flight Time) under Supplemental Operations for FEs and Navs, are you an FE?

I think you're legal. You will be subject to a limit of 100 block hours in 30 days based on your schedule so far. Once you mix 2-man operations AND augmented crew ops, you are limited to 100 hours for 30 consecutive days.

I am legal according to the ALPA lawyers, but I still don't see why.

According to my issue, I would think I would be governed by 121.525 (a, and c). which refers to 121.521 (a) that would make me limited to 12 aloft.

"Not so" says the attorneys,
According to their interpretation, I am governed by 121.525 (a-b). Which refers to 121.503, and 121.509. 509 applies.

Thanks for the backup, I think I will go try to find the rest of my hair I have pulled out trying to figure this out.

Just call in sick and have a beer. :)

You cannot figure out most of these things just by reading the regs, you need to look at the legal interps and case law. The lawyers have done that.
